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.

orig. publ. Not an Acraspis but an Antron of the present monograph. 
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 ter- 
minal tuft of hairs, the spine is not like that of true Cynips.

Dryophanta in orig. publ. Dryophanta or Diplolepis of most later au- 
thors. 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. Spathe - 
gaster in orig. publ. Dryophanta and Diplolepis of later authors. I 
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. 
Longicornis Bassett, 1900, Trans. Amer. Ent. Soc. 26:327. Dryo- 
phanta 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. Dryo- 
phanta 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
