which is not fine but which does not show any of the broadening char 
acteristic of true Cynips. 
Compressus Gillette, 1891, Bull. 111. Lab. Nat. Hist. 3: 197. Acraspis 
in orig. publ. and later authors. I have seen the National Museum 
type. The tarsal claws are simple, the wings entirely lacking, and the 
hypopygial spine long, very slender, with scattered hairs but without a 
tuft of hairs terminally. The gall occurs on black oak. All of these 
characters disagree with those of true Cynips. Weld (1926, Proc. U.S. 
Nat. Mus. 68 (10) : 55) considers this insect a Zopheroteras. 
Confusa Ashmead, 1881, Trans. Amer. Ent. Soc. 9: XVIII. Cynips 
in orig. publ. Neuroterus, Dryophanta, and Diplolepis of later authors. 
The National Museum types are lost. From the original description, 
this black oak insect appears to belong to the palustris group, and it 
would be ruled out of true Cynips on the same basis as palustris (q.v.). 
Corrugis Bassett, 1890, Trans. Amer. Ent. Soc. 17: 71. Dryophanta 
in orig. publ. Dryophanta or Diplolepis of later authors. I have seen 
the types in the Philadelphia Academy. The thorax is largely smooth 
and shining but transversely wrinkled, the wing veins are very pale and 
almost colorless, and the hypopygial spine, altho rather stout and well 
developed, is not broadened and does not have the terminal tuft of hairs 
of a true Cynips. 
Cressoni Beutenmiiller, 1913, Trans. Amer. Ent. Soc. 39 : 248. Dryo- 
phanta in orig. publ. Not known except from the holotype which is in 
the Beutenmiiller collection and inaccessible at this time. Unless the 
description is correct in recording the radial cell as closed, I can see no 
warrant in this original publication either for including or excluding 
this apparently bisexual insect from true Cynips. 
Discalis Weld, 1926, Proc. U.S. Nat. Mus. 68 (10): 24. Diplolepis 
in orig. publ. I have seen the holotype at the National Museum and 
several paratypes. The insect belongs to the discus group and is ruled 
out of true Cynips on the same basis as discus (q.v.). 
Discularis Weld, 1926, Proc. U.S. Nat. Mus. 68 (10): 25. Diplolepis 
in orig. publ. I have seen the holotype in the National Museum and 
several paratypes. Belongs to the discus group and is ruled out of true 
Cynips on the same basis as discus (q.v.). 
Discus Bassett, 1900, Trans. Amer. Ent. Soc. 26 : 326. Dryophanta 
in orig. publ. Dryophanta and Diplolepis of later authors. I have seen 
the holotype and paratypes in the Philadelphia Academy. The insect 
is quite small, the hypopygial spine is long, very slender, without a 
terminal tuft of hairs, and very different from true Cynips. The gall 
is a small, thin, and flattened disc bearing no resemblance to any Cynips 
gall except that of guadaloupensis. The agamic insects emerge early 
in the spring, several months after most Cynips. 
Dubiosa Fullaway, 1911, Ann. Ent. Soc. Amer. 4: 339. Diplolepis in 
orig. publ. and later authors. I saw the Stanford types some years ago, 
and now have large series of collected material. This bisexual insect
