Kinsey: Gall Wasp Genus Cynips

with the mesonotum very smooth and shining, the hypopygial spine 
rather slender, blunt, and without any broadened area, and the eyes of 
the male prominently enlarged. The galls and life histories differ from 
true Cynips. 
Yaecinii Ashmead, 1887, Trans. Amer. Ent. Soc. 14: 127, 136. Acras- 
pis in orig. publ. Acraspis, Zopheroteras, Trigonaspis , and Philonix of 
later authors. I have studied the holotype and the paratype in the 
U.S. National Museum. The tarsal claws are simple, the wings entirely 
lacking, and the hypopygial spine long, very slender, with scattered 
hairs but without a tuft terminally. These are not Acraspis characters. 
Vacciniifoliae Ashmead, 1896, Proc. U.S. Nat. Mus. 19:130. Cal- 
lirhytis in orig. publ. Diplolepis in Weld 1926: 36. I have seen the 
National Museum holotype and numerous paratypes. The thorax of the 
insect and the oak-apple type of leaf gall are similar to those of true 
Cynips; but the insect differs materially from Cynips in its rather fine 
wing venation, its radial cell which is very long, straight, and narrow, 
and its hypopygial spine which is very slender, sharply pointed, slightly 
curved, and without a terminal tuft of hairs. 
Vesiculoides Ashmead, 1896, Proc. U.S. Nat. Mus. 19: 114. Dry- 
ophanta in orig. publ. Dryophanta and Diplolepis of later authors. I 
have seen the holotype at the National Museum. The bisexual insect 
has a blunt hypopygial spine which is not fine but which does not show 
any of the broadening characteristic of true Cynips.
