Diese Art tritt in 3 verschiedenen Formen auf: 1. einer Frühjahrsgeneration mit dunklem Hinterleib, A. Trimmerana K., 2. einer Frühjahrsgeneration mit teilweise rotem Hinterleib, A. spinigera K., und 3. einer Sommergeneration, A. Rosae Pz. Der erste, welcher die Zusammengehörigkeit dieser 3 Formen oder Rassen erkannte, war Edward Saunders. In seiner Synopsis of British Hymenoptora, P. I. (Trans. Ent. Soc. 1882, p. 243) zieht er A. spinigera K. als Varietät zu A. Trimmerana K., und in den Hymenoptera Aculeata of the British Islands 1896, p. 237, werden die beiden genannten Formen als Varietäten zu A. Rosae Pz. gestellt. Meines Erachtens dürfen …

I make a new name for our species without hairs on the metanotum, not knowing whether it will include the typical Ageuia or not. The type of Melanaporus Ashm. is a two-celled form of P. argenteus or a close ally.

New Elementary Agriculture, Charles E. Bessey, Lawrence Bruner, Goodwin D. Swezey

School of Biological Sciences: Faculty Publications

This is an agricultural nation. The products of the soil are the basis of her industries and her prosperity. The children of our great Commonwealths should be familiar with our crops, our grains and grasses, our flowers and fruits, our trees and shrubs and weeds, our domestic animals and birds and insects. Our children should have a practical knowledge of the management of a farm, of the composition of the soil, and of the adaptability of the farm and its soil for the cultivation of certain plants and the counter effect of such plant growth upon the soil. They should …

The Aspens: Their Growth And Management, William Grant Weigle, Earl Hazeltine Frothingham

Aspen Bibliography

The aspens, or "popple," as they are often collectively termed, occupy a peculiar position in the forests of North America. Growing up rapidly and in great abundance over areas which have been deforested, usually by fire, they attain only a small size, produce a soft, weak wood, extremely valuable for a limited number of uses, and die at a relatively early age.

Present Methods Of Teaching Entomology At The University Of Nebraska, Lawrence Bruner

Department of Entomology: Faculty Publications

'When our Secretary sent out his preliminary notification of this meeting and asked me to take part in a discussion of "present methods of teaching Entomology," the matter at first seemed of little importance so far, at least, as the speaker was concerned. However, after giving the subject some thought I have decided that it might be well at least to take the time and trouble to attempt to explain briefly a few of the methods by which the student in Nebraska is enabled to absorb some entomological information. In order to do this with an unbiased feeling it might …

Botanical Teaching, Charles E. Bessey

Discussion And Correspondence Coupling Vs. Random Segregation, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

To the editor of science: The suggestion offered by Morgan, in SCIENCE of September 22, to account for the coupling and repulsion of factors for various characters in inheritance in such forms as Abraxas, Drosophila, fowls, sweet peas, etc., incites this note.

Briefly Morgan's hypothesis is (1) that the materials representing factors that couple are "near together in a linear series" in the chromosomes; (2) that, when pairs of parental chromosomes conjugate, "like regions stand opposed "; (3) that "homologous chromosomes twist around each other," but that the separation of chromosomes is in a single "plane"; (4) that, thereby the …

Bulletin No. 111 - The Reclamation Of Seeped And Alkali Lands, C. F. Brown, R. A. Hart

UAES Bulletins

In the year 1905, Drainage Investigations were begun in the State of Utah by the Office of Experiment Stations of the United States Department of Agriculture, in co-operation with the Utah Experiment Station. Appropriations have been made by the Utah State Legislature for irrigation and drainage investigations on condition that the United 8tates Department of Agriculture contribute an equal amount, and that the work be conducted jointly by the Federal department and the experiment station of the Agricultural College of Utah.

Bulletin No. 113 - The Influence Of The Combined Harvester On The Value Of The Wheat, Robert Stewart, C. T. Hirst

UAES Bulletins

The extension of the dry-farming area in Utah and the bringing of many thousands of acres of virgin land under wheat cultivation, in large farms, has, in recent years, caused much improvement in the use of farm machinery. One great improvement has been the adoption of the Combined Harvester, which cuts, threshes and sacks the grain in one operation in the field at a minimum of cost. This has been an important factor in the success of the dry-farming movement.

Bulletin No. 112 - A Report Of Seven Years' Investigation Of Dry Farming Methods, Lewis A. Merrill

UAES Bulletins

The permanent settlement of Utah was made possible because of the introduction of irrigation methods but the growing of crops without irrigation was successfully practiced soon after the settlement of the territory. From the existing records and from the words of many of the veterans still living it is evident that many attempts were made to grow wheat in the early 50's without irrigation. Most of these attempts failed, because they were made on irrigated lands. In 1865, however, an experiment on a much more extended scale was made.

New Studies Of The Arrhenuri, Ruth Marshall

School of Biological Sciences: Faculty Publications

Since the publication of "The Arrhenuri of the United States," in 198, the author has been fortunate enough to secure enough more material to justify the publication of a supplementary paper on this large genus of water-mites. This material consists of collections from new localities in the United States, and of additional material from old collecting grounds, together with a few specimens from other countries. The author's own collections were made in Wisconsin and Illinois. A few new places were visited, as the lakes about Milwaukee ; and more extensive collections were made in previously known bodies of water, as …

Bulletin No. 110 - The Alfalfa Leaf-Weevil, E. G. Titus

UAES Bulletins

The alfalfa leaf-weevil (Phytonomus murinus Fab.) which has during the last three years been doing considerable damage in the central part of this State, is a European insect which by some means unknown has been introduced in to Utah. The species appears to be not uncommon throughout Europe and parts of Asia and Africa. It belongs to the large order of hard-shelled insects called beetles (Coleoptera) and in a group generally called snout-beetles (Family Curculionidae). To this same group belong many of our most serious pests, such as the plum curculio, cotton boll-weevil and strawberry weevil.

It occurs over all …
