In H. juglandis, among 5 cases of thely-toky, 3 showed orange daughters from heterozygous mothers. One of these mothers was Oo Dll dll Ww, the daughter oo Dll Dll Ww. Five males with mosaic eyes were produced from heterozygous mothers. 1 bred as black, 1 as orange, and 1 from mother, Oo Dll dll Ww Dx dx, had mosaic gonads producing sperm, (309) o Dll W Dx and (11) O Dll W dx as indicated by daughters. One male and 1 female with mosaic wings are reported. Among 12 gynandromorphs, 1 indicates paternal influence on female parts (eyes), 2 maternal influence on male parts, and 1 that male parts are exclusively maternal. The evidence is consistent with the hypothesis that the 1st oocyte division may be either reductional or equational, that in thelytoky the 2nd division is omitted, that in formation of mosaic males 2 ootids take part, and that in gynandromorphs male parts are formed from one ootid, female parts from fusion of another ootid with sperm nucleus. In H. brevicornis 2 gynandromorphs and 4 inter-sexual males are described. Gynandromorphs are grouped with respect to their reactions as typically or predominantly male, typically or predominantly female, or sexually indifferent. Responses are appar-ently governed by head, but conflicting tendencies of abdominal origin are evident.
