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.

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 …

The material here listed came, unless otherwise stated, from the island of Dominica and was collected during June and July, 1913, by Mr. H. W. Foote. As almost nothing has been recorded in the Hymenoptera from this island, the collection is of especial interest.

While collecting Ichneumonoidea in New Brunswick, Mr. A. Gordon Leavitt also collected a number of other Hyrnenoptera, and below is given a report on most of the Apoidea. Some of the material, mostly Megachilinae, Sphecodes and male Halictus, has not been identified, and is not included. A few of the determinations were made by Mr. H . L. Viereck, and credit is given in the proper places.

In this paper where both sexes of a species are described, that last described is the allotype. Comparative measurements where given in figures were made with the Zeiss binocular microscope equipped with No. 2 eyepieces and the a3 objective and an eyepiece micrometer.

Most of the species described in this paper are of economic importance, and for reference in economic literature their early description is desirable. The series from the species of Agromyza is noteworthy in view of the number of species previously described as parasites of the species of that genus. In this paper, in all cases where both sexes of a species are described, that last described is the allotype.
Notes On Some Species Of The Genus Prosopis, J. C. Crawford
Notes On Some Species Of The Genus Prosopis, J. C. Crawford

This is a valid species, and not a form of P. cressoni as it is given by Metz. Externally the two are easily seperable. P. cressoni has the propodeum coarsely sculptured, while Mesilla has it, very finely wrinkled. The eighth ventral plates of the males are quite different, and are therefore figured. In cressoni the apical lobes are much shorter than the pedicel attaching them to the plate; in Mesilla they are longer than the pedicel.
