than the prominent eyes; abdomen slender, dorsally carinate, 

 tipped with coarse white spines; entire body covered with fiae 

 white pubescence; thorax and abdomen sparsely set with curved 

 black hairs pointing backward. Length of full-grown larvae 

 5.50 mm. 



Lirvse and adults were taken the first week in July; adults 

 contiQuing 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, Euacanthus interruptus L., have been represented 

 in American collections but have been placed with Pitch's orhi- 

 talis. Those at hand are from South Carolina, but it doubtless 

 has much the same distribution as acuminatus here, as it doas in 

 Europe. 



The position of the ocelli in this genus is strongly suggestive 

 of the AcocepJialince , while in some other respects it appears to 

 be more closely related to the Tettigonime. 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 101. The female taken at Ames this season 

 differs considerably from the male description, and may be 

 characterized as follows: 



Female. — General aspect of £'uaca«t7<ti.s; 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 Euacanthus, but lacking the ciriEa3, 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 XestocepJialus, about one- 

 third the distance from the eye to tip. Front at ocelli one-half 

 wider than at lorse. Antennae 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 as in Euacanthus. Elytra about 

 equaling the abdomen; spines on the hind tibias very strong,
