Elongate (twice as long as wide) , uniformly dark brown to reddish 

 brown, strongly shining (when not covered with foreign matter), 

 the palpi and antennal club slightly paler. 



Head transversely depressed behind clypeus, coarsely, confluently 

 granulose or tuberculose, rather densely clothed with short, semi- 

 erect, yellowish hairs; clypeus broadly truncate or feebly, arcuately 

 emarginate in front. Antenna extending to base of elytra, rather 

 densely clothed with short, semierect, yellowish hairs; eighth segment 

 rounded. 



Pronotum strongly, irregularly convex, slightly wider at base than 

 at apex, widest behind middle ; sides slightly flattened, strongly mar- 

 gined, oblique anteriorly, and broadly rounded posteriorly, the mar- 

 gins coarsely uniformly crenulate ; anterior margin strongly lobed at 

 middle; base broadly subtruncate; surface feebly, longitudinally de- 

 pressed at middle, densely, uniformly granulose, the granules elevated 

 and distinctly separated, sparsely, irregularly clothed with erect, arcu- 

 ate, yellowish hairs, which are denser along lateral margins. 



Elytra at base subequal in width to pronotum behind middle ; sides 

 parallel, conjointly broadly rounded at apices; disk strongly convex, 

 sometimes with an obsolete longitudinal elevation on each elytron near 

 apical declivity and parallel with suture; surface sparsely, coarsely, 

 irregularly granulose, sparsely, irregularly clothed with long, erect, 

 arcuate, yellowish hairs, the hairs forming a dense fringe along lateral 

 margins, and each arcuate hair on disk having a distinct spur. 



Body beneath finely, densely, uniformly granulose, rather densely 

 clothed with long, recumbent, yellowish hairs. 



Length 3-5 mm., width 1.5-2.5 mm. 



Type locality. — Maine; type probably lost. 



Distribution. — This species occurs everywhere in the region east of 

 the Eocky Mountains. Material has been examined from Delaware, 

 District of Columbia, Illinois, Indiana, Iowa, Kansas, Long Island, 

 Maryland, Massachusetts, Michigan, Missouri, New Jersey, New York, 

 North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, and 

 Manitoba. 



Host. — Adults have been reared from the woody fungus, Polyporus 

 gilvm Schw. Blatchley (1910) records it on woody fungi beneath 

 bark of trees and shrubs and also at maple sap in spring. 



Dejean (1835, 1836) listed this species under the genus Cis from 

 "Amerique Boreale," without giving any description. Randall (1838)
