NATIONAL MUSEUM Vol. 92 Washington : 1942 No. 3150 THE GENOTYPES OF SOME OF ASHMEAD'S GENERA OF ICHNEUMON-FLIES By R. A. CusHMAN In the keys to his Classification of the Ichneumon Flies, Ash-mead ' proposed 21 genera with so-called manuscript species desig-nated as genotypes. That is, these genera and their genotypes were described only by the key characters leading to the genera. Some of these have since been more fully described by Ashmead or by other authors, but several are still in their original status. One genus, ostensibly of this sort, was described by Ashmead prior to 1900. In the foUow'ing pages I shall indicate the relationships of these genera and redescribe the genotypes that have not already been redescribed. Genus ZONOCRYPTUS Ashmead Zonocryptus Ashmead, Proc. U. S. Nat. Mus., vol. 23, p. 40, 1900. (Genotype, "Cryptus sph'mgiH Ashmead, manuscript," monobasic.) The genotype was said to be from Africa. The only specimen in the collection in the United States National Museum that ful-fills all the requirements of character and habitat is a male labeled "Ex sphinx chrysalis from Central Africa, I. Helen Moffat (Den-ton)" and bearing the name label '■'•Cryptus formosus Br." in Ash-mead's handwriting. There can, I think, be no doubt that the genus Zonocryptus was based on this specimen. 1 Proc.
