JTahhat Teneriffam, a raeipso semel tantum repertus. 



The unique example from which the above diagnosis has been com- 

 piled was captured by myself in Teneriffe ; but I have unfortunately 

 no recollection as to its precise locality. I believe, however, that it 

 was probably found either in the vicinity of Orotava or else of S*" 

 Cruz. Luckily the species has such decided characters of its own 

 that a single individual is abundantly sufficient for distinguishing it. 

 Perhaps its most remarkable feature is the comparatively immense 

 length of its second fnniculus-joint, which is almost (if not indeed 

 qiate) twice as long as the basal one. But apart from this, the L. 

 ohscurus may be fiirther recognized by its black surface, which is 

 sparingly clothed with minute cinereous scales, or pubescence, but 

 which is free from additional erect hairs ; and by its rather opake, 

 subalutaceous, and Ijasally-trisinuated elytra. Its eyes are somewhat 

 small and round ; and its prothorax (which is a little convex) is 

 deeply and sharply punctured, but with the diminutive intermediate 

 punctules shallow and not very dense. Its male sex (of which I can 

 alone speak) is slender in outline ; but in all probability the females 

 would be broader and more ovate.

This is one of the most distinct Laparoceri hithei-to detected, and 

 apparently peculiar (so far at least as observed hitherto) to Gomera 

 — where, at the beginning of February 1858, I brushed it from off
