178 Ml'. T. Vernon Wollaston on the EttpJwrhia-infesting 



genus has yet been published, it must necessarily (if it cannot be 

 amalgamated with Deucalion) be cited as Leprosoma.

The L. gibbum is probably far from scarce if searched for in its 

 proper localities ; but as it is apparently peculiar to the rotten 

 Etipliorbia-stems, it might (like most of the species enumerated in 

 this Memoir) be easily overlooked by a casual collector in the island, 

 who might have but litile time for observation, and would not be 

 aware of the interesting fauna nourished by that singular race of 

 plants. I have seen the larvae, however, of this fine Longicorn in 

 considerable profusion, and have taken the perfect insect not un- 

 commonly, on the mountains above Santa Cruz of Teneriffe (in the 

 direction of Las Mercedes), as well as near Betancuria (in the 

 Rio Palmas) of Fuerteventura. It secretes itself beneath the loose 

 outer fibre, generally of the larger trunks, and makes a loud stridu- 

 lation when captured, Ijke the species of Deucalion, by the upward 

 and downward movement of its head and prothorax, — an operation 

 which causes the inner surface of the pronotum to slide over the 

 dorsal file with which its mesonotum is furnished.

The present genus, I am informed by M. Thomson, is identical 

 with Slenidea of Mulsant and Dcroplia of Dejean's Catalogue;
