and is shaped much like that of the last described species (S. 

 angulicolUs) , with the exception of the anterior angles which are 

 square and sharp. The elytra are profoundly striated, and thi-re 

 are several irregular depressions over their surface.

Length If lines. 

 Brassy black with a silken gloss on the elytra, legs and 

 antennae brown. The thorax has a shagreen appearance, is 

 finely canaliculated, is largely rounded at the apex and base, and 

 has both anterior and posterior angles very sharp and prominent. 

 Each angle is furnished with a long seta. The elytra are opaque 

 and striated, the interstices are somewhat rounded. There are 

 three shallow impressions along the third interstice.

I am not quite sure of the identity of this insect with the one 

 described by Count Castelnau.

Length 5 lines. 

 Of a short oval form, with the upper surface of a glossy black, 

 without puncturation or marking, and with only faint traces of 

 striee on the elytra. The under surface is of a pitchy red. 



I cannot find anything that answers to this insect among the 

 species of this genus described by Count Castelnau, but there are 

 so many of them almost exactly alike, that I am not at all con- 

 fident as to its being undescribed.
