Professor Cockerell has recently (Psyche, XXIII, 176- 178, 1916) published on the synonymy of this group, and at present it seems best to treat Zacesta and Panurgomyia as synomyms of this genus. Z. rufipes is very similar to the genotype of Hesperapis and is probably the male of a very closely allied species. Panurgomyia fuchsi belongs to the group of H. eumorpha and (Panur-gus) H. regularis Cress. and is very close to regularis. The type of fuchsi is in bad condition and the identification is, therefore, somewhat' uncertain.

There are many facts in the taxonomy and still more in the life-histories of the common American wasps (Vespa) which need a thorough revision. The following small contribution is made with the hope of interesting other entomologists in the subject. During the last summer, the .writer made a point of capturing all the specimens of wasps he met with on his collecting trips, but the result as a whole was very poor, 1916 apparently not being a wasp-year. However, amongst the catch were found two females which he was unable to refer to any of the species previously known from …

In the course of investigations of Dinocampus americanus (Riley), a common Braconid parasite of many of the larger species of Coccinellids, conducted in relation to cereal and forage crop insects, several interesting features have developed, not the least important of which is the discovery that parasitism is not invariably fatal to the beetles.
