The above rather indefinite description i- really all that can he said directly of this 

 species. T have in my cabinet a long series, the sculpture and punctation varying to an 

 extent rendering it impossible to ti\ even a standard. Specimen 1 is sub-opaque, thorax 

 and elytra verj densely and rather coarsely aciculately punctured, the elytra are obscurely 

 tricostate, with the interstices obsoletely reticulate. From this point the sculpture be- 

 comes gradually less defined, and finally the species becomes as smooth and shining as 

 any specimens of viatica. As compared with viatica, it is more robust and obtuse. The 

 legs are also stouter and the tarsal joint- less -lender. Notwithstanding the rather coarse 

 punctation of the elytra, tin- sculpture is verj different from that seen in the next -roup, 

 where the -paces between the punctures are notably elevated and rounded. The larger 

 proportion of the specimen- of robusta are entirely smooth. The width of the species 

 between the humeri is equal to half the length. 



c. opaca, elongate oval, I. lack, sub-opaque, sides sub-parallel, bead finely punctured, thorax finely ami 

 rather densely punctured, int. n ry finely alutaceous, sides rounded, gradually nan-owing from the hind an 



elytra finely but less densely punctured; less frequentlj ferruginous brown. Length .36 .43 iuch. 



Net rare in Owen-' Valle) and at Fort Tejon, California. 



Similar in form to the preceding, but much -mailer. The legs and tarsi are more 

 -lender and resemble those of viatica and puncticcllis. Very distinct from any of our spe- 

 cie-, though hardly separable from the preceding by description.
