prothorax (the former of which is large and round, whilst the latter 

 is considerably abbreviated and much narrowed behind) are almost 

 free 'from sculpture, but its elytra are rather distinctly punctured. 

 The only specimen which I have seen is due to the researches of Dr. 

 Crotch in Teneriffe, during the spring of 1862.

A single example of this beautiful Oclitlienomus was captured by 

 myself, during June 1858, at a high elevation in the island of Palma 

 — at the base of some damp, trickling rocks above the Pinal of the 

 Banda, close to the edge of the great Caldeira.

This beautiful XylopMlus, the elongated antenniB of which (with 

 their abbreviated second joint) and enlarged subconfluent eyes, in the
