Description. — Piceous to rufopiceous, pronotum and elytra gen- 

 erally more rufous. Head about six-sevenths as wide as pronotum; 

 eyes scarcely at all prominent; clypeus feebly broadly emarginate, 

 angles somewhat prominent; labrum very short, a little emarginate 

 above declivity, alutaceous; outer antennal segments about as wide 

 as long; with rather coarse punctures especially at sides; obsoletely 

 alutaceous, Pronotum one-twelfth wider than long, rather strongly 

 narrowed behind, base three-fourths as wide as apex ; lateral margin 

 not at all widened posteriorly; with an impressed midline set off by 

 irregular rows of punctures; with very coarse punctures sometimes 

 united longitudinally, separated transversely by less than twice their 

 width; alutaceous ground sculpture almost completely obsolete. 

 Elytra about as wide as ijronotum, a little longer than wide, parallel ; 

 finely coriaceous; with very coarse and irregular punctures, more 

 or less serial; not alutaceous. Abdomen not alutaceous, except 

 vaguely apically; very coarsely but not muricately punctate. An- 

 terior face of front tibia with a few very fine scattered setigerous punc- 

 tures. Length, 4 to 6 mm. 



Type locaUty. — ''America septentrionali." 



Types. — Presumably in the Zoologische Museum, Berlin. 



Records. — The following are the records known to me: 



Cuba: Soledad (Darlington, 1937). 



North America: Flobida, Alabama, Virginia, District of Columbia, Maryland, 

 Pennsylvania, Ohio, Kentucky, Indiana, Iowa, Nebraska, South Dakota, 

 Kansas, Missouri, Arkansas, Texas (Gravenhorst, 1800; Say, 1834; Nolman, 

 1925; Darlington, 1937; etc.). 



8pecime7\s examined. — I have examined many examples from 

 North America, but from the West Indies I have seen only the 

 example collected by Dr. Darlington. 



Remarks. — The only West Indian specimen known was collected 

 by Dr. Darlington in Cuba. He records that it has the head more 

 strongly alutaceous than is usual in this species. The above de- 

 scription was taken principally from specimens collected near 

 Washington, D. C. 



It lias been collected in the United States from South Dakota 

 to Texas and from Florida to New England.
