ately arcaately advanced ; aiitennis moderately stout, third and fourth joints 

 constricted slightly at middle ; thorax wrinkled all over but not deeply, median 

 line very fine ; the lateral margin tine and but slightly reflexed, attaining the 

 base ; sides of thorax feebly arcuate, moderately convergent to base ; elytra 

 elliptical, widest in front of the middle, moderately convex, closely not deeply 

 punctate, towards apex confusedly punctate. 



Hahifftt—M-dnposa, Co., Cal. (Coulterville). 



This species looks like Lecontei, but is smoother, and differs in the 

 form of the labrum and in the scidpture of the head. It occurs, 

 moreover, in the Sierra Nevada, while Lecontei is confined to the 

 Southern Coast Range. Its nearest relative in the Sierra is tiequoi- 

 arum, from which it differs by its more elongate form. It is probably 

 in many collections under the name of sequoiarum and in some cases 

 as Lecontei.

^afeitol— Vancouver Island, Washington, Oregon, Northern Cali- 

 fornia, Montana. April to July. Our largest species, easily distin- 

 guished by the irregular fovese of the elytra. Sometimes obtained in 

 numbers by breaking up rotten trunks of trees. Dr. Van Dyke tells 

 me there is no recent record of the occurrence of this species in Cali- 

 fornia.

Schaupp compares this species with Dejeani, which it does resemble 

 in being more depressed above than our other species and in being 

 larger, but otherwise it is more likely to be confused with some of the 

 following species. The nearly straight sides of the prothorax and the 

 comparatively smooth surface seem to me its distinguishing characters.
