On The Status Of Some Species Of The Genus Panurginus, J. C. Crawford Dec 1912

On The Status Of Some Species Of The Genus Panurginus, J. C. Crawford

Co

In a paper on the bees of Nebraska, Messra Swenk and Cockerell say that a comparison of cotypes of Panurginus nebrascensis with specimens of P. ornatipes shows that the two are synonyms and that P. boylei is a subspecies. The types of all of the involved species being in the collections of the U.S. National Museum has led to a re-examination of them and the characters given show them to be abundantly distinct. In view of these characters, what Messrs. Swenck and Cockerell has under the name ornatipes is somewhat of a mystery.

The North American Digger Wasps Of The Subfamily Scoliinae, Oscar C. Bartlett

Ba

This contribution to our knowledge of the sub-family Scoliinae (digger wasps) found in North America, Central America and the West Indies, is the result of work done at the Massachusetts Agricultural College under the direct supervision of Doctor H. T. Fernald, and forms a portion of a thesis for the degree of doctor of philosophy. In it, an attempt has been made to place before those interested, a paper in which our present knowledge of these wasps is systematically arranged and the identification of the species facilitated.

Descriptions Of New Hymenoptera No. 5, J. C. Crawford Sep 1912

Descriptions Of New Hymenoptera No. 5, J. C. Crawford

Co

Many of the species herein described were received from the Bureau of Entomology, United States Department of Agriculture, having been reared by its various branches in economic investigations as parasites of injurious insects. In this connection attention is especially called to the interesting and varied series reared from Agromyza. In this paper, as in all previous papers published by me, the sex first described is to be taken as the true type and the second as the allotype.
