The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout Jan 1939

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout

Bulletin of the University of Nebraska State Museum (1924–2023)

The rich and varied nature of the mammalian faunas of the White River Oligocene has been recognized for many years, but the exact geologic succession is only now becoming known. In these faunal assemblages the rodents and lagomorphs appear to have been important elements, perhaps numerically as abundant in the Oligocene as are these same groups at present.


The Spiders Of South Dakota, Allan G. Peterson Jan 1939

The Spiders Of South Dakota, Allan G. Peterson

Electronic Theses and Dissertations

Spiders constitute the order of Araneida, which is one of the principal divisions of the class Arachnida. The Arachnida also includes scorpions, whipscorpions, pseudosscorpions, harvestmen, mites, and ticks. Some of the distinguishing characteristics of the Araneida are as follows: The head and thorax are consolidated into a cephalothorax. The abdomen is unsegmented and joined to the cephalothorax by a short narrow stalk. There are six pairs of appendages on the cephalothorax: chelicerae, pedipalps with heir basal masticulatory endites, and four pairs of walking legs.

Report Of Progress Of The Nebraska State Museum, Erwin H. Barbour Jan 1938

Report Of Progress Of The Nebraska State Museum, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

The history and development of the Nebraska State Museum since 1891 have been summarized in a preliminary manner up to 1925 in the first number of Volume I of the Bulletin of the Nebraska State Museum.1 Since 1927, the collections of the Nebraska State Museum, The University of Nebraska, have been housed in a new building, Morrill Hall, on the city campus of The University of Nebraska. It now seems fitting to report upon the exceptional progress of the past few years, and to acknowledge the fine cooperation of those who have helped to make it possible.


The Life History Of The Dewberry Fruit Worm Cacoecia Rosaceana (Harr.) In Utah, Merlin W. Allen May 1937

The Life History Of The Dewberry Fruit Worm Cacoecia Rosaceana (Harr.) In Utah, Merlin W. Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study has been to determine the identity and the life history of certain larvae attacking dewberry fruits and foliage in a few sections of Utah. The dewberry fruit worm as it was called until it was definitely identified the oblique-banded leaf-roller, was first observed by farmers at Granite and Butlerville in 1932. Since 1934 it has been found affecting dewberries in other parts of northern Utah.

This investigation was begun in the spring of 1935 and continued until the fall of 1936, being made possible through the Utah Agricultural Experiment Station, Department of Entomology, and with …


The Gizzard Worm And Its Transmission To Chickens In Hawaii, Joseph E. Alicata Jan 1937

The Gizzard Worm And Its Transmission To Chickens In Hawaii, Joseph E. Alicata

Harold W. Manter Laboratory of Parasitology: Library Materials

Gizzard-worms of poultry, Cheiloapirura hamulosa, are nematodes occurring in the gizzards of chickens and turkeys.

Summary and Conclusions

Previous to this report the carriers for the gizzard-worm in Hawaii were unknown. Recent investigations by the writer have shown that the flour beetle, Tenebroides nana, and the sand hopper, Orchestia platensis, collected from poultry farms in the Territory of Hawaii have been found naturally infested with the infective larvae of the poultry gizzard-worm, Cheilospirura hamulosa. Out of 8 laboratory-raised chickens to which there were fed about 2,300 grasshoppers that had been collected in an endemic gizzard-worm area, …


A Further Study Of Utah Asilidae, D. Elmer Johnson May 1936

A Further Study Of Utah Asilidae, D. Elmer Johnson

Theses and Dissertations

This study is based on a similar study made by Claudeous J. D. Brown in 1928, and published in 1929. The species he used have been rechecked, and additional ones have been studied. The species considered in this study represent three of the four subfamilies of North American Asilidae. These three subfamilies are Dasypogoninae, Laphriinae, and Asilinae. This study is limited to those species in the Brigham Young University Collections, and to species recorded in print. No claim is here made that all the forms inhabiting the state have been discovered, in fact the writer is well aware of the …


Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1936

Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

There has been much discussion recently relative to the geologic age of Yuma and Folsom artifacts. The writers submit the following palaeontological and geological data which may aid in a better interpretation of the subject. This paper deals with three localities in Nebraska where Yuma and Folsom implements have been found with extinct mammals; namely, the Scottsbluff Bison Quarry, the Sand Hill blow-out sites, and the Sioux County artifact sites.


A Key To The Nebraska Cutworms And Armyworms That Attack Corn, Don B. Whelan Jun 1935

A Key To The Nebraska Cutworms And Armyworms That Attack Corn, Don B. Whelan

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The following key to the Nebraska cutworms and armyworms injurious to corn is based upon structural characters supplemented in some instances by color. Not all of the species in this key have been found in Nebraska; some are included because they are to be found in near-by states to such an extent that they probably are present in this state.


A New Fossil Peccary, Prosthennops Niobrarensis, From Brown County, Nebraska, Edwin H. Colbert Jan 1935

A New Fossil Peccary, Prosthennops Niobrarensis, From Brown County, Nebraska, Edwin H. Colbert

Bulletin of the University of Nebraska State Museum (1924–2023)

During the summer of 1929, the writer, accompanied by Mr. Paul O. McGrew of the University of Nebraska, discovered during the course of excavations for fossil vertebrates in northern Brown County, Nebraska, a fairly complete peccary skull referable to the genus Prosthennops. This skull, due to its several unusual characters, as well as to its fair degree of completeness, would seem to warrant a special and a rather detailed description. Consequently the specimen has been kindly turned over to me by Dr. E. H. Barbour, Director of the Nebraska State Museum, not only for the purpose of the present …


A New Miocene Dog, Mesocyon Geringensis, Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1935

A New Miocene Dog, Mesocyon Geringensis, Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

A field party from the Nebraska State Museum consisting of Messrs. E. L. Blue, Frank Crabill, Loren Eiseley, and C. Bertrand Schultz, on August 28, 1931, was fortunate in finding the remains of a new Mesocyon. This specimen, number 4-28-8-31, the Nebraska State Museum, was found in the Gering formation (lower Miocene), fifteen feet above the Brule, 400 feet west of the road in Redington Gap, near the center of the S. 1/2, sec. 14, T. 19 N., R. 52 W., west of Bridgeport, Morrill County, Nebraska.


Gnathabelodon Thorpei, Gen. Et Sp. Nov. A New Mud-Grubbing Mastodon, Erwin Hinckley Barbour, George F. Sternberg Jan 1935

Gnathabelodon Thorpei, Gen. Et Sp. Nov. A New Mud-Grubbing Mastodon, Erwin Hinckley Barbour, George F. Sternberg

Bulletin of the University of Nebraska State Museum (1924–2023)

In February, 1932, while opening a gravel pit to get material for highway construction, the skull, tusks, and mandible of a new longirostral mastodont were found by Robert Arnold on his ranch, Sec. 24, T. 12 S., R. 22 W., 1 1/2 miles due east of Ogallah, Trego County, western Kansas. This point is located about 20 miles west and three miles north of Hays, the seat of the Fort Hays Kansas State College, in the museum of which the above mentioned specimen is mounted and exhibited. When unexpectedly exposed by Mr. Arnold and his associates, the great skull was …


Forest Fire Damage Studies In The Northeast--I. Bark-Beetles And Fire Damaged Hardwoods, Paul W. Stickel Oct 1934

Forest Fire Damage Studies In The Northeast--I. Bark-Beetles And Fire Damaged Hardwoods, Paul W. Stickel

The Bark Beetles, Fuels, and Fire Bibliography

In reporting the damage to trees scorched lightly at the base by fire the average fire warden and even the technically trained forester is given to stating that little harm has been done providing the tree crowns remain green. Such a statement is far from being correct, failing as it does to take into account the aftermath of insect and fungus damage which invariably follows even the lightest of surface fires. In the case reported herein, over 50 per cent of the fire-scorched hardwoods showed signs of the presence of ambrosia-beetles, whose work, even if the trees continue to live, …


A New Giant Camel, Titanotylopus Nebraskensis, Gen. Et Sp. Nov., Erwin H. Barbour, C. Bertrand Schultz May 1934

A New Giant Camel, Titanotylopus Nebraskensis, Gen. Et Sp. Nov., Erwin H. Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

The purpose of this bulletin is to figure and describe a .amel brought to light in the field season of 1933, which seems to be the giant of all camels found in the State. The specimen consists of the right ramus with the symphysial portion. The mandible is 26% inches long, or about the length of one's outstretched arm to the finger tips. This jaw is nine inches longer than that of Camelops kansanus. Such an extraordinary jaw indicates a camel nearly twice as large as Alticamelus altus. In reference to its unusual size we are proposing for it the …


A New Rhinoceros Mount, Trigonias Osborni, Erwin H. Barbour May 1934

A New Rhinoceros Mount, Trigonias Osborni, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

On February 9, 1934, a pair of rhinoceroses, Trigonias osborni, was installed in the Founder's Room in Morrill Hall, the Nebraska State Museum. They are figured and accorded brief consideration here in order to maintain the printed records of such acquisitions in the Nebraska State Museum. The two skeletons, carefully posed, were put in the south wall case to be associated with a pair of Diceratherium from Morrill County. and the mounted skeletons of two Brown County Te leo ceras. In this gallery two long built-in wall cases insure ample facilities for the proper installation of six rhinoceroses, for each …


A Study Of The Oviposition And Nymphal Development Of Paratrioza Cockerelli (Sulc) Upon Various Host Plants, Wylie L. Thomas May 1934

A Study Of The Oviposition And Nymphal Development Of Paratrioza Cockerelli (Sulc) Upon Various Host Plants, Wylie L. Thomas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The potato psyllid, Paratrioza cockerelli (Sulc) as stated by E. O. Essig, (1917) is a native of the western states.

Since the great outbreak of psyllid yellows in Utah potato fields in 1927 much interest has been given to this insect. The close relationship between the nymphs of P. cockerelli and the disease, psyllid yellows, is a well known fact, but as yet the causative factor by which this disease is produced still remains unknown.

Because of the severity of the disease to potatoes and the importance of knowing something of the host plants of P. cockerelli, the writer, …


A New Ovibovine, Symbos Convexifrons, Sp. Nov., Erwin H. Barbour Feb 1934

A New Ovibovine, Symbos Convexifrons, Sp. Nov., Erwin H. Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

In Bulletin 25, entitled The Musk-oxen of Nebraska, the writer figured and briefly catalogued the ovibovines of this State as known at that date. In the meantime an interesting new form unlike that of any species falling within our experience presents itself from the Pleistocene of Cherry County, Nebraska. The new specimen cannot be assigned a place in any of the four following genera: Preptoceras, Euceratherium, Ovibos, or Bootherium, but may possibly be referable to the genus Symbos, to which we are assigning it provisionally. It is so unlike Symbos, however, that it may be a distinct genus. …


The Nebraska Meteor And Meteorite Of August 8, 1933, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1934

The Nebraska Meteor And Meteorite Of August 8, 1933, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

At approximately 10:30 a. m., mountain standard time, on August 8, 1933, a large meteor, traveling in a westerly direction, exploded over the panhandle of Nebraska. The phenomenon was witnessed by many citizens throughout the region, and by a number of students from the University of Nebraska, who were engaged at the time in palaeontological field work in northwestern Nebraska .


A Mounted Skeleton Of Megabelodon Lulli, Erwin Hinckley Barbour Jan 1934

A Mounted Skeleton Of Megabelodon Lulli, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

A skeleton of Megabelodon lulli, partly composite, was mounted in the laboratory May 31, 1933, and was formally installed and placed on exhibition in Elephant Hall, June 7, 1933.


The Geology And Mammalian Fauna Of The Pleistocene Of Nebraska Part I Outline Of Pleistocene Geology Of Nebraska Part Ii The Pleistocene Mammals Of Nebraska, A. L. Lugn, C. Bertrand Schultz Jan 1934

The Geology And Mammalian Fauna Of The Pleistocene Of Nebraska Part I Outline Of Pleistocene Geology Of Nebraska Part Ii The Pleistocene Mammals Of Nebraska, A. L. Lugn, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

The object of the present paper is to provide a suitable brief statement of the present state of knowledge of the Pleistocene geology of Nebraska, for an adequate understanding of the Pleistocene Mammal list, by Mr. C. Bertrand Schultz, which forms Part II of this report. The "outline" is necessarily brief and does not contain many detailed sections, nor lengthy discussions of controversial points. It is lacking in adequate detailed descriptions of new formations and may not be entirely convincing to many readers. The only excuse which the writer can offer for the shortcomings of the following pages is the …


A Study Of The Sculpture Of The Chorion Of The Eggs Of Eighteen South Dakota Grasshoppers (Acridiidae), Raymond Cecil Bushland Jan 1934

A Study Of The Sculpture Of The Chorion Of The Eggs Of Eighteen South Dakota Grasshoppers (Acridiidae), Raymond Cecil Bushland

Electronic Theses and Dissertations

The most destructive grasshoppers that occur in South Dakota are those belonging to the genus Melanoplus. Of those, the common and harmful species are Melanoplus bivittatus (Say) and Melanoplus differentialis (Thomas). Other species that are of considerable economic importance, and, at times, fully as important as the two species mentioned, are Melanoplus femur-rubrum (Deg.) and Melanoplus mexicanus (Sauss.). Before attempting to work out a plan for grasshopper control, it is desirable at times to know what species are to be encountered. The control may vary to some extent for the different species. It has been found that Melanoplus differentialis hatches …


Contributions To The Anatomy Of The Mature Larva Of Papilio Polyxenes Fab. (Lepidoptera: Papilionidae), Ernst J. Dornfeld Apr 1933

Contributions To The Anatomy Of The Mature Larva Of Papilio Polyxenes Fab. (Lepidoptera: Papilionidae), Ernst J. Dornfeld

Bachelors’ Theses

Thia study was undertaken with the purpose of gathering more comprehensive information on the larval anatomy of a typical member of the lepidopterous family Papilionidae. Except for investigations dealing with the osmeteria, literature on the general anatomy of this otherwise well known family is very scant. Because of the relatively small number of speci­mens that were available for study, this paper has been limi­ted to a discussion of the external anatomy and of the gross . morphology of the digestive tract, the urinary system, the silk glands, and the mandibular glands. Important papers in which these structures have been …


A Key To Differentiate Nymphal Stages Of Melanoplus Differentialis (Thomas) From Those Of Melanoplus Bivittatus (Say), (Orthoptera); Also, Descriptions Of Instars And A Key For Identification Of Nymphal Stages Of These Two Species, Gerald Bishop Spawn Jan 1933

A Key To Differentiate Nymphal Stages Of Melanoplus Differentialis (Thomas) From Those Of Melanoplus Bivittatus (Say), (Orthoptera); Also, Descriptions Of Instars And A Key For Identification Of Nymphal Stages Of These Two Species, Gerald Bishop Spawn

Electronic Theses and Dissertations

During the past few years South Dakota and neighboring states have been confronted with serious outbreaks of locusts. Whole crops of small grain and corn have been destroyed by the voracious insect hordes which at times left only bare ground where once had stood waving fields of grain. Chief among the aggressors have been the two species, Melanoplus differentialis (Thomas), the Differential Locust, and Melanoplus bivittatus (Say), the Two-Striped Locust. The contents of this paper include studies of these two species.


The European Pine Shoot Moth (Rhyacionia Buoliana Schiff.): With Special Reference To Its Occurrence In The Eli Whitney Forest, Roger B. Friend, Allen S. West Jr Jan 1933

The European Pine Shoot Moth (Rhyacionia Buoliana Schiff.): With Special Reference To Its Occurrence In The Eli Whitney Forest, Roger B. Friend, Allen S. West Jr

Yale School of the Environment Bulletin Series

The European pine shoot moth has been recognized as a pest .in Europe for over a century. It was first discovered in the United States in 1914, since when it has become a serious enemy of red pine. The insect is becoming increasingly abundant in this country and is known to be present in Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, West Virginia, Illinois, Ohio, Michigan, possibly Florida, and in the provinces of Ontario and British .Columbia in Canada. Some fifteen species of pines susceptible to injury in varying degree have been reported as hosts .of this insect, …


The Articulated Skeleton Of Titanotherium, Erwin H. Barbour Jan 1932

The Articulated Skeleton Of Titanotherium, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

The skeleton of a titanotherium, stored since 1894, was installed in the west corridor of Morrill Hall, April 28, 1931. In the meantime the specimen has been visited by many citizens, women's clubs, and especially by delegations of school children, boy scouts, and like organizations, from various parts of the State and elsewhere. Repeated requests for a popular report on this particular specimen actuates the writing of this leaflet. Titanotheres were by far the largest creatures of Oligocene time in Nebraska. In point of size they are called gigantic, elephantine, and titanic. The titans of Greek mythology were giants, and …


The Scottsbluff Bison Quarry And Its Artifacts, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1932

The Scottsbluff Bison Quarry And Its Artifacts, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

The association of artifacts with extinct bison bones in a quarry near Grand Island, Hall County Nebraska,1 and from one in Custer County, Nebraska, have already been reported.2 In the meantime, continued search has been rewarded, and a large bed of fossil bison with associated flint implements found. The discovery, if not of actual consequence, at least adds something to the accumulating evidence that Pleistocene man in America may have been a reality.


Association Of Artifacts And Extinct Mammals In Nebraska, Bertrand Schultz Jan 1932

Association Of Artifacts And Extinct Mammals In Nebraska, Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

During the past four years the Nebraska State Museum, under the directorship of Dr. Erwin Hinckley Barbour, has been making even more extensive palaeontological collections throughout Nebraska than heretofore. As work progresses, especially with fossil bison and mammoth, there is increasing evidence that man appeared in Nebraska much earlier than is generally believed. Two occurrences of artifacts associated with fossil bones will constitute the main theme of this paper.


The Mounted Skeleton Of Bison Occidentalis, And Associated Dart-Points, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1932

The Mounted Skeleton Of Bison Occidentalis, And Associated Dart-Points, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

A composite skeleton of Bison occidentalis was mounted and installed in its case on the lower floor of Morrill Hall, on April 22, 1932. The skeleton in itself is attractive because of its size and excellent preservation, and is rendered additionally interesting by two dart-points, one found under the scapula, and the other under the ribs.


A New Oreodont Slab, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1932

A New Oreodont Slab, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

A slab of pale, reddish-brown sandstone, exhibiting the articulated skeletons of two oreodonts, has been placed on display in the west corridor on the first floor of Morrill Hall. Apparently, a female and well-grown young one lay down together and perished, perhaps from disease, or from chilling winds. They must have been buried quickly, for all of the bones are present, are in perfect condition, and are in articulation, especially in the old one. In the adult the articulation is complete from the ungual phalanges of the two forefeet to the terminal caudal, even though in the figure the skeleton …


The Mandible Of Platybeldon Barnumbrowni, Erwin Hinckley Barbour Jan 1932

The Mandible Of Platybeldon Barnumbrowni, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

Platybelodon barnumbrowni was described originally as Torynobelodon barnumbrowni.1 The Nebraska State Museum was visited and this unique specimen studied by Dr. Henry Fairfield Osborn and Dr. Walter Granger, August seventeenth and eighteenth, nineteen hundred and thirty-two. It is the opinion of both that this specimen belongs properly to their Mongolian genus Platybelodon. With certain reservations the writer wishes to defer instantly to their judgment, which is based on unequalled experience. It is perfectly apparent that this form makes a close approach to the remarkable Platybelodons found by Granger and Andrews in the Gobi Desert of Mongolia, later figured and …
