The sides of the thorax are less rounded, the disc less convex, and the margin more 

 evident, especiall) near the hind angles. The elytra arc more elongate, more nearl) par- 

 allel, lis- convex, and more coarsel) punctured and opaque. 



Length .16-.20 inch.

('. el on gat us, elongate, sub-parallel. Head reddish brown, coarsely and rather closely punctured. Tho 

 Bub-quadrate, somewhat broadei than long, sides rounded anteriorly, straight and sub-parallel behind, distinctly mar 

 gined, margin slightly reflcxed; apex feeblj emarginate, angles obtuse; base stronglj sinuous, angles prominent back- 

 wards; disc moderately convex, coarselj I at not closelj punctured. Elytra i ub-parallel, denselj muricatelj 

 punctured, faintly sub-striate. Under surface and legs brownish or ferruginous. Length .11 .18 inch. 



As in the other species, the body is ferruginous or brownish in color, the elytra alone 

 being black and more or less opaque. The thorax at base i- strongly sinuous, especially 

 within each hind angle, the latter being rendered therebj more prominent behind. The 

 sides of the bod) are also more parallel. The muricate punctures of the elytra are fur- 

 nished each with a very short coarse, curved hair. The elytra of seriaiits are entirely de- 

 void of hairs, they are probably found on recent or well preserved specimens of parallelus, 

 while in this species the) are probably permanent and undoubtedl) more dense than it is 

 possible for them to be in the latter species. The females are larger and rather more ro- 

 bust than the males, while the latter have the anterior and in less degree the middle tarsi 

 feebly dilated. 



Occurs rather abundantly under stones in Owens' Valley, California.

The differences between this genus and the preceding have already been adverted to, 

 and need hut little additional mention. In this the npper portion of the eye is larger and 

 broader transversely, occasionally sub-angulate within. The antenna' are more slender 



than in Conibius, and graduall) thickened toward the tip. 



Our species are numerous and may be distinguished by the characters in the following 

 table: 



Thorax w ith a broad flattened margin. 



Alternate interspaces of elytra elevated. sordidus. 



[nterspai es equal, elytra deepl) striate. sulcata-. 



Thorax convex from the edge. 



Elytra black or brown, without metallic lustre ; stria' continuous. 



Elytra with golden yellow hair-. auripilis . 



Elytra \\ ith greyish hairs.
