Below is given a table of the American genera, exclusive of Crelioxys, assigned by Ashmead to his subfamily Crelioxyinre. As Prof. Cockerell has long ago pointed out, these are not all closely related and must be split up into several groups, so my table is one of convenience only.

Als H. Stichel im Jahre 1899 den mitteleuropäischen Parn. apollo von der nordischen Rasse unter dem Namen geminus abtrennte, hat diese Teilung nicht die uneingeschränkte Anerkennung der Entomologen gefunden und als er dann später im Jahre 1906 noch die Unterart melliculus aufstellte, bedeutete diese Neuerung „ einen Stich ins Wespennest", wie er sich selbst ausdrückte. Der Grund hier-für ist jedoch kaum in einem Mangel der Zweckmäßigkeit begründet, sondern der ungenauen vom Autor selbst nur als relativ brauchbar bezeichneten Diagnose zuzuschreiben. Für SticheI bedeutete geminus einen Kollektivbegriff für „ die Gesamtheit der den europä-ischen Hoch- und Mittelgebirgen" angehörigen Formen mit Ausnahme …

In this paper are included, in addition to the descriptions of new parasites of economic importance, records of some North Dakota bees from O. A .

Bulletin No. 138 - How To Control The Grasshoppers, E. D. Ball
UAES Bulletins
There is no longer any reason why a farmer or a community of farmers should allow their crops and meadows to be destroyed by swarms of grasshoppers. Our knowledge of their habits has increased and better methods of destruction are known, so that at the present time the grasshopper takes its place in the list of crop pests that can be controlled by those who desire to do so. In the old days when countless numbers of the Rocky Mountain locusts (M. spretus) settled down on the crops of the few scattering settlers of the plains or Intermountain region, there …

The Bee Genus Holcopasites Ashmead, J. C. Crawford

This genus was established by Dr. Ashmead in Trans. Amer. Ent. Soc., vol. 26, p. 82, 1899, but no species was included. The material on which he based his description is in the U. S. National Museum and bears his manuscript name H. pratti. This, however, is the species described by Robertson as Philerenius illinoiensis, which species I select as the genotype. To this genus also belong Phileremus pulchellus Cresson, P. heliopsis Robert., and Neopasites robertsoni Cwfd. as well as the new species described below.
