Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson
Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson
Conservation and Survey Division
The purpose of this study is to describe and correlate rocks of Mississippian age within the state of Nebraska. Shales, generally classified as "Chattanooga" and commonly referred to as Devonian or Mississippian in the northern Mid-Continent, have been included in this study, although these shales are more generally believed to be Devonian and not Mississippian by most stratigraphers and paleontologists at the present time. Since rocks of Mississippian age are present only in the subsurface of Nebraska, the basic information for this report is derived from the microscopic study of cuttings and cores from test wells drilled within the state.

The Bdellidae (Acarina) Of The Australian Realm, Warren T. Atyeo
Bulletin of the University of Nebraska State Museum
Although primarily a systematic study, variations in the integumental striae and chaetotaxy of the legs are discussed. The genus Octobdellodes Atyeo, 1960 is synonymized with Bdellodes Oudemans, 1937 and the sugenus Cytobdella Mihelcic, 1958 is synonymized with Cyta von Heyden, 1826. The genus Bdellodes is divided into the subgenera Bdellodes and Hoploscirus Thor, 1937 (=Thoribdella Grandjean, 1938, new synonymy). Twenty-two species are now known to occur in New Zealand and the outlying islands. These include four known species: Bdella iconica, Bdellodes (Roploscirus) lapidaria, B. (R.) reticulata, and Cyta latirostris, and eighteen new species: Bdellodes (Bdellodes) harpax, B. (B.) oraria, …

Bulletin of the University of Nebraska State Museum
Two new species from Mexico, Melissodes (Tachymelissodes) sonorensis and M. (Melissodes) tescorum, are described in this paper. The previously undescribed males of M. cerussata LaBerge and M. baileyi Cockerell are described. Notes concerning the key to species of the subgenus Callimelissodes are given. New records of the following poorly known species of Melissodes are included: M. opuntiella, M. sphaeralcea, M. fimbriata, M. baileyi, M. apicata, M. mitchelli, M. intorta, M. flexa, M. maesta, M. cerussata, M. expolita, M. fasciatella, M. floris, M. …

Bulletin of the University of Nebraska State Museum
A third genus in the tribe Anthophorini in the vI/estern Hemisphere, genus Deltoptila, is described in this work. Previously described species included in the genus are as follows: D. melanopyrrha (Dours), D. elefas (Friese), D. fulva (Smith), D. bombyformis (Smith), D. montezumia (Smith), D. aurulentocaudata (Dours), D. agilis (Smith), D. costaricensis (Friese). New descriptions and records are given for D. montezumia, D. aurulentocaudata, D. agilis and D. costaricensis. Two new species are described: D. afimbriata and D. pexata.
