Species of the Pacific coast regions. 



Femora pale rufous, the extreme apex alone abruptly blackisli. 



Body slender, the vestiture less dense, the semi-erect hairs brown- 

 ish priiinosiis Lee. 



Body stout, more densely pubescent, all the hairs whitisli. 



incanus n. sp. 

 Femoi'a l)lack, slightly rufescent at base; til>ioe pale rufous. 



variipes n. sp. 



Femora and tibia- black throughout iiiclutlis n. sp. 



Head much smaller and narrower than the prothorax; body large and stout, 



the vestiture very dense throughout iiiiiiius n. sp. 



Vestiture of the elytra not uniform in distribution. 



Elytra closely and finely mottled with small irregular clusters of only 



slightly greater density; legs testaceous throughout rilflpej^ n. sp. 



Elytra more sparsely variegated with large spots of more condensed white 

 pubescence. 

 Legs completely black throughout. 



Pronotum scjircely at all impressed laterally. Wyoming to Oregon. 



SUttatii!^ Lee. 

 Pronotum strongly' impressed in the middle toward the sides.

 Legs rufous, the femora black except at base suballiicaiis n. sp. 



There can be no doubt whatever of the identity of CEdemei'a 

 vestita Say (Journ. Ac. Nat. Sci., Phila., Ill, 1823, p. 2T3) with 

 S. hadiijyennis Lee, and the species is closely allied to mellyi Laf., 

 though probably distinct. It is possible that Eurijgenius muri- 

 nus may be better placed in the present genus, but a renewed 

 inspection of the palpi would be necessary- to decide. 



The species of Stereopalpus are ver^- uniform in structure 

 throughout, and have comparatively feeble sexual characters ; 

 the male has a small terminal and densely punctate genital seg- 

 ment, which is but little protruded. The eyes are broadly and 

 feebh' sinuate anteriorly. 



S. iiicanus. — Slightly stout, black, densely clothed with stiff white pu- 

 bescence which, on the elytra, does not quite conceal the surface lustre, and 

 which as usual there consists of .'short semi-erect sparser hairs mingled with 

 recumbent pubescence. Head finely, densely rugo.so-i)unctate and dull; eyes 

 convex, prominent, separated by twice their own width, narrowly rounded 

 beneath, broadly above, obliquely truncate behind and surrounded, especially 

 behind, by a fine polished glabrous line; antennae black, the basal joint rufes- 

 cent, slightly longer than the head and ])rothorax combined; clypeus twice as 

 wide as long, rectangular and transversely truncate, not differing in sculpture. 

 Pro^/(a/7(.c sculptured like the head, rather longer than wide, rounded on the .sides 

 anteriorly, thence just percei)tibly narrowed and l>roadly, distinctly sinuate
