elevation very narrow, but punctate. Legs pale rufo-piceous. Length .05 — .08 

 inch. ; 1.25 — 2 mm. 



This species varies in the manner indicated for melanocephalas. 

 The discal space of the elytra may cover fully half the entire area 

 or it may be reduced to an indistinct cloud around the scutellum. 



Resembles in general appearance and coloration inelanocephahis, 

 but is always smaller and with pale epipleurre. The punctuation of 

 the elytra is much less distinct than that of the thorax. 



AVidely distributed over the eastern United States from Canada 

 to Maryland. In the eastern hemisphere it is spread throughout 

 Europe, northern Africa and northern Asia. It seems to have a 

 tendency to become cosmopolitan. 



C. iligriceps Marsh. — Oval, morlerately convex, piceons. shining, sides of 

 thorax indefinitely paler; elytra reddish testaceous, with a common fuscous spot 

 behind the middle. Antennae and palpi pale testaceous. Head distinctly, not 

 closely i>unctate. Thorax regularly convex, sides arcuately narrowed from base 

 to apex, basal marginal line distinct at the s^des, a slight impression in front of 

 scutellum, surface finely not closely punctate. Elytra moderately deeply striate, 

 the tenth obliterated, striae relatively coarsely punctate, the intervals slightly 

 convex, scarcely distinctly punctate; epipleurse pale. Body beneath, opaque 

 black, raetasternal area shining, punctate, prolonged by an elevated line to the 

 anterior angles. Prosternum distinctly cariuate, mesosternal elevation linear, 

 smooth. Legs rufo-testaceous. Length .05 — .08 inch. ; 1.25 — 2 mm. 



In many specimens the metasternal area is pale. In the majority 

 of the native specimens examined the median fuscous cloud of the 

 elytra is very indistinct, but when distinct it forms a broadly cres- 

 centic transverse band, while specimens often occur with the elytra 

 entirely pale. 



From its small .size this species cannot be mistaken for any other 

 except, possibly, pygmceus, which, apart from color, differs in the 

 absence of a basal marginal Hue. 



In our country this species is widely diffused, and is known to me 

 from Canada to Louisiana and Indiana, also from Los Angeles, Cal. 

 In its distribution in the eastern hemisphere Bedel remarks that it 

 is almost cosmopolitan. 



C. Iiigubris Payk. — Oval, convex, narrower behind, piceous black, sub- 

 opaque, entire surface finely alutaceous ; elytra at apex with a well defined pale 

 space extending along the side margin. Autenupe rufo-testaceous, club slightly 

 darker, palpi testaceous, last joint darker. Head moderately, finely, closely 

 punctate. Thorax piceous, near the side margin indistinctly paler, sides regu- 

 larly arcuate and narrowed to apes ; basal marginal line wanting, a faint basal
