Mannerheim says that this species is allied to his C. brunni- 

 pennis, but is shorter, and is besides distinguished by having 

 the antennae thicker, the thorax shorter, its sides more rounded, 

 and the elytra rounded at the apex. 



Collected in carcases in the months of July and August by 

 M. Frankenhauser on the banks of the Tschunuktnu in the 

 Peninsula of Kenai : not frequent.

 " Piceus, fulvo-sericeus, dense punctulatus ; thorace an- 

 trorsum subangustato, lateribus rotundatis, basi late 

 rotundato ; elytris obsoletissime striatis, stria suturali 

 profundiore ; antennis basi testaceis ; tibiis calcaribus 

 mediocribus armatis. 

 " Long. If lin. 



" The anterior tarsi and first joint of the middle tarsi of the 

 male are moderately dilated ; the antennae are as long as the 

 head and thorax, moderately thickened ; the seventh joint is a 

 little larger than the sixth, and equal to the ninth ; the eighth 

 is about one-half smaller *." 



The above is Dr. Leconte' s description ; the following is Say's : 



" Pale brownish, sericeous ; terminal and five basal joints of 

 the antennae rufous. Inhabits Arkansas. Head dark ferru- 

 ginous; antennae dark ferruginous, the five basal joints and 

 terminal joint rufous ; palpi and mandibles ferruginous ; thorax 

 rather paler than the head, quadrate, a little transverse, sides 

 regularly arcuated ; posterior margin not wider than the ante- 

 rior ; posterior edge rectilinear ; angles rounded ; elytra paler 

 than the thorax, light brownish, with obsolete striae, more ob- 

 vious towards the tip; very numerous minute punctures fur- 

 nishing minute hairs ; beneath piceous ; feet rufous ; thighs yel- 

 lowish beneath. Length nearly /^ths of an inch. This species 

 occurred on dungf." 



Dr. Leconte in speaking of his species remarks, that he is not 

 positively certain that it is Say's species, which was found in 

 Arkansas, while his was from New York. He adds, "The thorax 

 is more narrowed in front than described by him ; although the 

 legs are in reality black, the lustre of the fulvous hair is such, 

 that one might readily be tempted to describe them as testaceous 

 at base/'
