 at sutura elytrorum omnino concolor. Corpus cinereum pedibus nigris. 



The description is worthless, as is indicated by the expression thorax 

 leevis. The specimen upon which it was based, should probably be re- 

 ferred to Rhinoncxs pericarpius, p. 284.

California, San Francisco. The detailed description gives no farther char- 

 acters for the recognition of this species.

 aninus}.

The reference to Centrinut seems to me doubtful, in view of the expres- 

 sion Coleoptera abdomine bremnra. I have seen nothing that could be 

 properly referred to this description.
