UHLER ON INSECTS. 437 



yellow, lacking the raised chevron in front of them, and having traces 

 only of the obliqne grooves and central line ; front moderately flat, the 

 tylus prominently raised, polished, bald, cylindrical ; the labrum much 

 broader, acutely angular at tip, a little longer than the tylus, and of 

 the same testaceous color, or both black. Eyes large, prominent, 

 brown, placed very obliquely. Rostrum reaching to the posterior coxae, 

 piceous, paler at base and tip. Autenute black, remotely bristly, the 

 first two joints often paler above; the basal joint stout, increasing in 

 thickness beyond the base; the second joint more than twice as long 

 as the first, a very little enlarged at tip ; the third and fourth longer 

 than the basal, subequal, the third a little thicker, both slender on the 

 ends. Prouotum subcampanulate, narrow, very much rounded in front, 

 the lateral margins flattened and a little reflexed, but tapering very 

 slenderly in the direction of the collum, before reaching which it turns 

 downward and fades out ; the anterior lobe very narrow, but strongly 

 convex, indented on the middle and constricted in front, more or less 

 golden pubescent, and punctate in the depressed lines ; the posterior 

 lobe flattened, transversely a little wrinkled, shagreened, and some- 

 what pubescent ; the posterior margin deeply concavely sinuated, the 

 humeral angles produced, broad, flat. Scutellum densely shagreened, 

 sparingly pubescent, a little convex at base, and depressed before the 

 tip. Prosternum either black, or broadly margined each side behind 

 with white, and, together with the disks of all the pleural pieces, pu- 

 bescent and rugulose. Coxse terminated with piceous or testaceous, the 

 femora pale piceous or yellowish, darker at the knees, and sometimes 

 with a few brown dots on the sides; tibise yellow, infuscated at tip, and 

 with the spines piceous; tips of the tarsal joints dusky or piceous, 

 with the nails paler. Hemelytra highly polished coal-black, reuiotely 

 set with shallow punctures, faintly golden pubescent, the costal margin 

 strongly arcuated, at base broadly expanded, and a little upturned, the 

 edge recurved, and the area very broad, the upturned margin continued 

 tapering to near the tip of corium ; the clavus bounded on the inner sub- 

 margin and outer suture by impressed punctate lines; membrane almost 

 as thick as the corium, black, tinged with piceous, sometimes with 

 about three pale brownish spots in the longer areoles. Yenter brilliant 

 black, closely, minutely punctate, coated with sparse, fine pubescence. 

 The hemelytra are Vider at base than the pronotum, and they gradually 

 widen in their curve posteriorly. 



Length to tip of venter 5-6 millimeters; to end of membrane C-7 

 millimeters. Width of base of pronotum scant to full 2 millimeters. Full 

 width across the corium 3-3i millimeters. 



The greatest number of specimens thus far acquired have been from 

 Eastern Massachusetts. Mr. Sanborn collected several near Andover ; 

 Mr. Scadder secured one in the vicinity of Lake Winnipeg ; Robert Ken- 

 nicott found it in British America, near Mackenzie River; other speci- 

 mens have been sent to me from Northern Illinois ; and the Museum of
