The male has unusually long antennae, these being very nearly as long as the whole body, 10-jointed with one ring joint, the first flagellar joint fully twice as long as the scape, following joints subequal to the first, the two apical ones very slightly shorter. The head and thorax in both sexes are rather coarsely shagreened with some indistinct umbilicate punctures, the face with convergent striae. ON THE SYSTEMATIC POSITION OF THE GENERA COLLYRIA SCHIODTE AND ISCHNOCEROS GRAVENHORST (HYMENOPTERA). By R. a. Cushman, U. S. Bureau of Entomology . In a paper on the "Holarctic Tribes of the Ichneumon-flies of the Subfamily Ichneumononinae (Pimplinae) " ' Cushman and Rohwer eliminated the genus Collyria Schiodte from the subfamily Ichneumoninae and expressed the opinion that it should form a distinct subtribe in the tribe Mesoleptini, sub-family Tryphoninae. Further critical study of the genus, how-ever, indicates that this conclusion is wrong and that the genus should more properly be restored to the Ichneumoninae. In the tribal keys of Cushman and Rohwer, both in that based on females and in the general key, Collyria runs best to the tribe Odontomerini. In several of the key characters it resembles the Labenini: the form of the propodeum and first abdominal seg-ment and the position of the insertion of the latter on the pro-podeum and the form of the hind coxae; but otherwise apparent-ly has little in common with that tribe. The Odontomerini, on the other hand, it resembles in the swollen head with the eyes nonemarginate and distant from the mandibles, in the strong notauli, in the lack of the areolet and in the venation of the wings generally, in the stout hind femora, and somewhat in the form of the abdomen beyond the first segment. But, in addition to the characters by which it resembles the Labenini, it differs from the Odontomerini in the incompletely areolated and mutic propodeum, the normal tibiae in the female, the form of the ovipositor, and the hairy eyes. Were Collyria to be included in the Odontomerini it would destroy the homogeneity that characterizes that group; and I believe that the best disposition to be made of it is to erect a new tribe for its sole reception. Tribe Collyriini, new tribe. The keys of Cushman and Rohwer cited above will have to be modified as follows for the inclusion of this tribe. Under the iProc. U. S. Nat. Mus., vol. 57, 1920, p. 395.
