than the prominent eyes; abdomen slender, dorsally carinate, 
tipped with coarse white spines; entire body covered with fine 
white pubescence; thorax and abdomen sparsely set with curved 
black hairs pointing backward. Length of full-grown larvae 
5.50 mm. 
Larvae and adults were taken the first week in July; adults 
continuing to be found throughout the month. Swept from a 
woody pasture in which numerous compositce abounded. Larvae 
in cages fed indiscriminately on a variety of plants taken from 
similar situations. 
Although not hitherto recorded specimens of the other Euro- 
pean species, Euacantlms interruptus L., have been represented 
in American collections but have been placed with Fitch’s orM- 
tails. Those at hand are from South Carolina, but it doubtless 
has much the same distribution as acuminatus here, as it does in 
Europe. 
The position of the ocelli in this genus is strongly suggestive 
of the Acoceplialince^ while in some other respects it appears to 
be more closely related to the Tettigonince. This and the fol- 
lowing genus, which seem very closely allied, may very probably 
represent generalized or intermediate forms connecting the two 
sub families.

The male of this species was described in “Hemiptera of 
Colorado,” page 104. The female taken at Ames this season 
differs considerably from the male description, and may be 
characterized as follows: 
Female. —-General aspect of Euacantlms; light yellowish- green 
above, no dark markings visible on the scutellum. Below, yel- 
lowish-green with rostrum, oviduct and spines on legs orange. 
Vertex furrowed and nearly parallel margined next the eye as 
in Euacantlms, but lacking the carinae, then convexly conically 
rounding to the front; length on middle twice that next the 
eyes, width between eyes equaling length. Ocelli small, on 
the rounding margin of vertex as in Xestocephalus, about one- 
third the distance from the eye to tip. Front at ocelli one-half 
wider than at lorae. Antennee inserted beneath a ledge, nearly 
as long as body; first and second joints large; pronotum very 
short on the middle, continuing broadly behind the eye and 
around back of the gen^ as in Euacantlms. Elytra about 
equaling the abdomen; spines on the hind tibiae very strong,
