HOR1STONOTUS. 273 



Two specimens , San Diego , California. As in the other species 

 of this division of the genus (1) , the posterior angles of ihe thorax 

 are longer than in the species above described (2) , and project 

 directly backwards : the basal striae are tolerably long, but faint : 

 the disc of the thorax is obsoletely channelled posteriorly : the ely- 

 tra are more rounded at the humerus than in the other species , 

 and are not wider than the (horax.

Two specimens , San Diego. Independently of size , distinguis- 

 hed by the piceous antennce from the preceding , which it very 

 much ressembles in forme : the striae of the elytra are less impres- 

 sed than in C. aufflatus : the thorax is rufo-piceous in one spe- 

 cimen.

One specimen, San Jose, California. The species is allied to the 

 next (curiatus), but the thorax is much more rounded on the sides : 

 the basal striae are reduced to extremely short fissures , and the 

 space around them is broadly an tolerably deeply foveate : the hu-
