(J. parallelus, Lee, loo. oil. 



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

 evident, especially near the hind angles. The elytra are more elongate, more nearly par- 

 allel, less convex, and more; coarsely punctured and opaque. 



Length .1G-.20 inch. 



Occurs at San Jose, Cal. 



C. elongatus, elongate, sub-parallel. Head reddish brown, coarsely and rather closely punctured. Thorax 

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

 gined, margin slightly reflexed; apex feebly emarginate, angles obtuse; base strongly sinuous, angles prominent back- 

 wards; disc moderately convex, coarsely hut not closely punotured. Elytra elongate, sub-parallel, densely muricately 

 punctured, faintly sub-striate. Under surfaoe and legs brownish or ferruginous. Length .1.4-18 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 is strongly sinuous, especially 

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

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

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

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

 while in this species they are probably permanent and undoubtedly 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. 



BLAPSTINUS, Latr.

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

 and need but little additional mention. In this the upper portion of the eye is larger and 

 broader transversely, occasionally sub-angulatc within. The antenna; are more slender 

 than in Conibius, and gradually thickened toward the tip. 



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

 table : 



Thorax with a broad flattened margin. 



Alternate interspaces of elytra elevated. 

 Interspaces equal, elytra deeply striate. 

 Thorax convex from the edge. 



Elytra black or brown, without metallic lustre ; striae continuous. 

 Elytra Avith golden yellow hairs. 

 Elytra with greyish hairs.
