with H. hordei Harris, stating that he had reared hordei from 
Elymus at Champaign, 111. The writer has examined these speci- 
mens and they are very clearly rufipes. The species resembles hordei 
somewhat in that the legs are reddish brown, but it is much larger 
than hordei and other characters very readily distinguish them. 
Rufipes is apparently a strictly western species, never having been 
reared any farther east than Champaign, 111. It has been reared 
from Elymus sp. collected in Kansas, Nebraska, New Mexico, and 
Utah. It has never been reared from any grass other than Elymus 
sp. Eepeated attempts were made by the writer to rear it in confine- 
ment at both La Fayette, Ind., and Charlottesville, Va., upon its host, 
but it has steadily and persistently refused to breed. It apparently 
would oviposit, but no larvae ever developed. It forms galls in the 
stems of Elymus sp. Nothing is known of its life history further 
than that it has a single generation during the year, hibernating in 
the usual way and emerging in May. Both sexes occur. 
HARMOLITA HESPERUS Phillips and Emery. 
Earmolita hesperus (10, p. 457) was considered by the writer for 
quite a while to be rufipes. The two species can be distinguished, 
however, very readily. H. hesperus is apparently a strictly western 
species, having been reared from Elymus sp. collected from Kansas 
and Utah, but it has never been found east of the Mississippi Eiver. 
H. hesperus forms galls very much as does elymicola. It has not 
been reared from any plants other than Hordeum jubatum and 
Elymus sp. Nothing is known of its life history further than that it 
hibernates in the usual way and emerges in May. Both sexes occur 
normally. The writer has never been able to rear this species in con- 
finement, though repeated attempts have been made to rear it in 
Elymus sp., both at La Fayette, Ind., and at Charlottesville, Ya. 
The egg is shown in figure 7 at a. 
HARMOLITA ELYMOPHTHORA Phillips and Emery. 
Earmolita elymophthora (10, p. 465) appears to be a strictly west- 
ern species also, having been reared only from Nebraska and North 
Dakota. It was first brought to the writer's attention by C. N. Ains- 
lie, who sent in galls on Elymus sp. from which was reared this 
species. It forms galls in Elymus sp. (PI. VI, D, E), though it is 
not known whether it has other hosts or not. It has refused to breed 
in confinement at Charlottesville, Va. It has one generation a year 
and both males and females normally occur. 
HARMOLITA OVATA Phillips and Emery. 
Harmolita ovata (10, p. 458) has been reared only from Kansas. It 
was sent to the writer in the fall of 1914 by E. O. G. Kelly, who was
