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 . Stevens, a series of specimens having been given to the United States National Museum. All the illustrations, with the exception of those of G. hagenowi, were made with a camera lucida.

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
The Bee Genus Holcopasites Ashmead, J. C. Crawford
Co
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.

Andrena Angustior W.K., Eine Duetsche Biene, J. D. Alfken
A
Eine Biene, dercn Vorkomrnen in Deutschland bisher noch nicht festgestellt, und die wahrscheinlich mu verkannt wurde, ist Andrena angustior W. K. Sie ist nahe verwandt mit A. gwynana W. K., mit der sie, wie aucb ilue noch naheren Verwandten A. rufula Schmied. und A. symphyti Schmied., in der Grofse und in der Farbung des Haarkleides fast ganz ubereinstimmt. Von A. gwyana unterscheiden sich die 3 genannten Arten sofort durch das wenigstens teilweise hell behaarte Gesicht, welches bei A. gwynana schwarze Haare tragt.

Problem Des Hummelstaates, Ludwig Armbruster
Problem Des Hummelstaates, Ludwig Armbruster

Die Honigbienen, dieses Paradigma der Biologie, geben trotz aller "Apistik" uns noch manche Rätsel auf. So wichtige Aufschlüsse wir für eine richtige Bewertung der Bienenbiologie aus einem eingehenderen Studium der Hummeln erwarten dürfen, so lückenhaft ist - freilich relativ gesprochen - andererseits das, was wir genaueres von deren Leben und Treiben wissen.

Die Fig. 18 ist, wie sich bei einem nochmaligen Vergleich mit dem Original herausstellt, durch die bei dem Stück allein vorgenommene Retouche der roten Flügelteile diesem so unähnlich geworden, daß es am besten ist, sie als nicht vor-handen zu betrachten. Als Type für die ab. interrupta hat dann die Figur Romanoff's in Rom. Mem. Lep. 1. (1884) pi. IV, f. 4 zu gelten.

This paper discusses only species occurring in America north of Mexico and no table to separate the males has been included since Prof. T. D. A. Cockerell published a table for this sex in the Canadian Entomologist for June, 1912, pp. 167-170. The key to the females includes all the species for the region under consideration in which the female sex has been described. In the table here presented the characters used for separating rufitarsis Sm. from comstockii Cress. and lucrosa Cress. from moesta Cress. are the characters used by Prof. Cockerell in a table to separate the types of …
