 broadened, and without a terminal tuft of hairs. The gall is a wool-covered larval cell attached directly to the leaf. The agamic insects emerge in March or April. None of these are Cynips characters.

Japonica Ashmead, 1904, Journ. N.Y. Ent. Soc. 12:79. Dryophanta in orig. publ. Diplolepis of later authors. I have seen the holotype in the National Museum. The mesonotum is smooth and shining, the hypopygial spine is short, not fine but pointed, and except for its terminal tuft of hairs, the spine is not like that of true Cynips.

Lanata Gillette, 1891, Bull. 111. Lab. Nat. Hist. 3:198, pi. 9 fig. 5. Dryophanta in orig. publ. Dryophanta or Diplolepis of most later authors. I have studied the National Museum types. The insect has simple tarsal claws, wing veins which are light in weight and color, and a hypopygial spine which is long, slender, somewhat curved, sharply pointed, and without a terminal tuft of hairs. The galls occur on black oaks. The adults emerge in the spring of the second year. These are very different from the characters of true Cynips.

Laurifoliae Ashmead, 1881, Trans. Amer. Ent. Soc. 9: XVII. Spathegaster in orig. publ. Dryophanta and Diplolepis of later authors. 1 have studied the National Museum types. They belong to the palustris group of insects and are ruled out of true Cynips on the same basis. See palustris in this list.

Liberaecellulae Gillette, 1889, Iowa Agric. Exp. Sta. Bull. 7:283, fig. 27. Dryophanta in orig. publ. Dryophanta or Diplolepis of later authors. I have studied four of the types at the National Museum. They are ruled out of true Cynips on the same basis as the other insects of the palustris group. See palustris in this list. Longicomis Bassett, 1900, Trans. Amer. Ent. Soc. 26:327. Dryophanta in orig. publ. Dryophanta or Diplolepis of later authors. I have studied the holotype and paratypes in the Philadelphia Academy. It is never easy to recognize a bisexual Cynips and the available material of this bisexual insect offers only one female and two males which are not sufficient for a precise generic assignment. The hypopygial spine of the one female specimen is not slender but not distinctly broadened as in Cynips. The spine has hairs at the tip, but the hairs hardly seem as long or as abundant as they are in bisexual Cynips.

Mitsukurii 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, the hypopygial spine is rather short, fine, nowhere broadened, without a terminal tuft of hair, and thus very different from true Cynips.

Nawai Ashmead, 1904, Journ. N.Y. Ent. Soc. 12:80. Dryophanta in orig. publ. Diplolepis of later authors. I have seen all the types in the U.S. National Museum. The mesonotum is smooth, naked, and
