Two new Silphids (Col.). 

 By (the late) FREDERICK BI,ANCHARD. 



The two new species of Cholcva in the Horn Collection 

 bearing my Mss. names of gratiosa and horniana, are sepa- 

 rated as follows : 



Thorax and elytra coarctate ; antennae with joints four and five 

 subquadrate, fourth a little longer, sixth slightly wider than long, 

 longer than the eighth, which is short transverse ; male hind 

 trochanters toothed ; fifth ventral female entire. clawcorms Lee. 



Sides of thorax and elytra nearly continuous; antennae with 

 joints four to six transverse, gradually wider, sixth equal to 

 eighth; fifth ventral of the female emarginate at middle of apex; 

 hind trochanters simple in the male. Tyngsboro, Massachusetts, V. 

 19. horniana n. sp. 



Gratiosa and alsiosa have the antennae longer than in the 

 other species, third joint longer than the second, fourth as 

 long as second; fifth ventral female entire. 



Eighth joint of ant-ennae longer, equal to the sixth or nearly so; an- 

 terior tibiae of male more slender, not curved or sinuate within ; 

 tarsi narrow in the same sex ; elytra paler. Rangeley Lake, Maine, 

 Aug. ist. gratiosa n. sp. 



Eighth joint of antennae very short, anterior tibiae of male stout, 

 curved; front tarsi broadly dilated; first joint of middle tarsi 

 wider ; color at maturity piceous or black. alsiosa Horn. 



[The above is an extract from a letter in reply to a request 

 for information pertaining to these species. 



The occurrence here at Chestnut Hill, Philadelphia, Penn- 

 sylvania, of both these Silphids and their incorporation under 

 the manuscript names in a list of the Coleoptera of Pennsyl- 

 vania soon to be published, makes it advisable to place the 

 above descriptions on record. CHAS. LIEBECK.]
