 has the hypopygial spine rather fine, blunt, and nowhere broadened, without a terminal tuft of hairs. The galls occur on black oaks. These are certainly not true Cynips characters.

Eburneus Bassett, 1890, Trans. Amer. Ent. Soc. 16: 70. Dryophanta in orig. publ. Dryophanta or Diplolepis of most later authors. I have seen the holotype in the Philadelphia Academy and several paratypes. The antennae are too short and too stout, the mesonotum too smooth, shining, and naked for an agamic Cynips. The hypopygial spine is somewhat broadened at base, but it is more slender and elongate than in Cynips. Incomplete data indicate a bisexual generation which is very different from true Cynips.

Emoryi Ashmead, 1896, Proc. U.S. Nat. Mus. 19:115. Dryophanta in orig. publ. Dryophanta or Diplolepis of later authors. I have seen the holotype in the National Museum and several paratypes. Originally described from the black oak, Q. Emoryi, but leaves with the types belong to the Q. undulata group of white oaks. The insect belongs to the eburneus group and is ruled out of Cynips on the same basis. See eburneus in this list.

Flavipes Fourcroy, 1785, Ent. Paris: 393. Diplolepis in orig. publ. and still maintained by Dalla Torre and Kieffer, 1910. The orig. descrip. obviously insufficient for identification of any cynipid.

Fuscus Fourcroy, 1785, Ent. Paris : 392. Based on Diplolepis No. 5 Geoffroy, 1762, Hist. Ins. 1: 311. Diplolepis in orig. publ. and still maintained by Dalla Torre and Kieffer, 1910. Orig. descrip. insufficient, and does not mention the gall, so the name is unrecognizable.

Glabra Gillette, 1894, Canad. Ent. 26:237. Dryophanta in orig. publ. Dryophanta or Diplolepis of most later authors. I have studied the holotype in the U.S. National Museum. The insect is close to eburneus Bassett and is ruled out of true Cynips on the same basis. See eburneus in this list.

Guadaloupensis Fullaway, 1911, Ann. Ent. Soc. Amer. 4:363, pl. 23 fig. 4. Acraspis acc. Weld 1926: 59. Not an Acraspis but an Antron as treated in the present monograph.

Hakonensis Ashmead, 1904, Journ. N.Y. Ent. Soc. 12:81. Dryophanta in orig. publ. Diplolepis of later authors. I have seen all of the type series in the National Museum. The mesonotum is smooth and shining and the hypopygial spine is slender, pointed, nowhere broadened, and without a terminal tuft of hairs. These are not true Cynips characters.

Ignota Bassett, 1881, Canad. Ent. 13:106. Cynips in orig. publ. Andricus, Dryophanta, and Diplolepis of later authors. I have seen the holotype in the Philadelphia Academy, and numerous paratypes thsre and in other collections. The insect bears little resemblance to a true Cynips. The mesonotum is prominently coriaceous and nearly naked, the scutellar foveae are well separated, the wing veins are rather fine and quite light in color, the hypopygial spine is slender, in no place
