 darker, its intermediate abdominal segments slightly blackened, and 

 with its hinder feet less elongate.

 Habitat in editioribus TeneriifaB et Gomerae, a DD. Crotch lectus. 



My original diagnosis of this Mycetoporus having been drawn out 

 from a single and rather immature example, which was captured by 

 Dr. Crotch (during the spring of 1862) in the higher elevations of 

 TenerifFe, I had no opportunity of perceiving that it varies consider-
