406 TRANSACTIONS OF THE 



sunken black pits, the posterior side and the margins each 

 side deeply sinuated; the mesonotal tablet large, distinctly 

 carinated, with a black dot on each side posteriorly. 

 Hemelytra narrow, with very few veins, two forks of 

 unequal length running back to the tip, veins obsoletely 

 and very sparingly flecked with brown, the apex narrow, 

 having four or five small apical areolets mostly caused 

 by forking of the veins, costal border often broadly white, 

 very moderately curved. Legs narrow, of medium length, 

 but little marked with brown, or obsoletely clouded, Meso- 

 and metasternum whitish, the latter deeply emarginate. 

 Base of venter also whitish. Anterior femora flattened, 

 posterior tibiae with five stout, piceous spines. Rostrum 

 reaching almost to the apex of the venter, as usual black 

 at tip. 



Length from eyes to tip of abdomen 4-43^ millims. : to 

 apex of hemelytra 4j^-5 mm. Width of pronotum 

 iy^ mm. Length of process i^ mm. Inhabits Arizona, 

 Colorado, New York and Massachusetts. 



Most of the specimens that I have seen were dull straw 

 color, with onl}^ faint markings on the hemel^^tra. The 

 fully developed specimens have the hemelytra about one- 

 fourth longer than the abdomen, and their color a dull 

 pale smoke brown, broadly bordered with white.

This species is closely related to the preceding, but has 

 a very short and slender cephalic process, the head is 

 closely set on the pronotum, the stout rostrum extends to 

 the posterior coxae, the legs are distinctly irrorated with 

 dark brown, and the mesopleura have a dark stripe on 

 the sides. 



This species has been taken in Dakota, Nebraska, 

 Minnesota, Connecticut, Massachusetts, Maryland, and
