 Parvula Bassett, 1900, Trans. Amer. Ent. Soc. 26: 326. Dryophanta in orig. publ. Dryophanta or Diplolepis of later authors. I saw the holotype at the Philadelphia Academy and concluded at that time that the insect was not a Cynips. The gall occurs on a black oak, which is not a Cynips character.

Patelloides Weld, 1926, Proc. U.S. Nat. Mus. 68(10): 60. Acraspis in orig. publ. Not an Acraspis but an Antron of the present monograph.

Pedicellatus Kinsey, 1922, Bull. Amer. Mus. Nat. Hist. 46: 284. Andricus in orig. publ. Dryophanta acc. McCracken and Egbert, 1922. I have re-examined the paratypes. The radial cell is long and narrow, the hypopygial spine is blunt and not slender, nowhere broadened, and without a terminal tuft of hairs. The gall of this bisexual insect is a precisely formed leaf gall. These are not Cynips characters.

Pedunculata Bassett, 1890, Trans. Amer. Ent. Soc. 17: 72. Dryophanta in orig. publ. Dryophanta and Diplolepis of later authors. I have seen the holotype, in the Philadelphia Academy, and several paratypes. This bisexual insect has a hypopygial spine which is slender, nowhere broadened, and without a terminal tuft of hairs. The gall is a precisely formed structure on the edges of the leaves of black oaks. These are not Cynips characters.

Perditor Bassett, 1900, Trans. Amer. Ent. Soc. 26: 313. Andricus in orig. publ. Incorrectly placed in Acraspis in Dalla Torre and Kieffer, 1910: 412, because Bassett's specimen had wings which were "not fully expanded." I have seen the holotype in the Philadelphia Academy. The wings are of full length altho crumpled. The thorax is transversely rugulose, the foveae are well separated, the second segment covers most of the abdomen, and the gall occurs on a black oak acorn. No one who has seen the insect has ever considered it an Acraspis.

Polita Bassett, 1881, Canad. Ent. 13: 99. Cynips in orig. publ. Dryophanta or Diplolepsis of all authors since Mayr, 1881, Gen. gallenbew. Cynip.: 36. I have seen the holotype, in the Philadelphia Academy, and several paratypes. The antennae are too short and the mesonotum is too smooth, shining, and naked for an agamic Cynips. The hypopygial spine approaches that of an Atrusca, and the galls bear a similar resemblance. The agamic insects, on the other hand, emerge in the spring, a month or two later than true Cynips, and we have incomplete data on an alternate generation of the genus to which polita belongs. This bisexual form is very different from true Cynips.

Politus Bassett, 1890, Trans. Amer. Ent. Soc. 17: 85. Acraspis in orig. publ. and later authors. Weld (1922: 8) considered this a Xystoteras. I have studied the holotype in the Philadelphia Academy. The hypopygial spine is rather long, very slender, and without a terminal tuft of hairs. It is certainly not an Acraspis.

Porterae Cockerell, 1900, Canad. Ent. 32: 91. Dryophanta in orig. publ. Diplolepis of later authors. I have studied the holotype in the
