448 Mr. T. V. Wollaston on the Canarian Malacoderms.

As will be gathered from the diagnosis, this Haplocnemus differs 

 from the preceding one (which at first sight it much resembles) in 

 being densely beset all over (in addition to the decumbent imder- 

 pile of its head and prothorax) with very long, fine, and erect hairs, 

 of which there is no indication whatsoever in the H. sculpiuratus. 

 Its elytra are perhaps a trifle less deeply punctured ; and the 

 antennae of its male sex are somewhat longer and thicker. Hitherto 

 I have observed it only in Hierro, where, during February 1858, I 

 captured five specimens of it in the sylvan district of El Golfo, on 

 the western side of the island.

Habitat in montibus Canarise Grandis, ad floras (prsesertim Cytisomm et 

 Cistorum) in pineto quodani excelso Tarajanse mensa Aprili, a.b. 1858, 

 rapertmn. 



The intensely black hue of this Melyrosoma, combined with its 

 short, robust, and decumbent pile, its subcorneal prothorax, and the 

 three very elevated costse with which each of its elytra is furnished, 

 will sufficiently characterize it. It is allied to the Madeiran M. 

 oceanicum, but is rather larger and of a deeper black, its pubescence 

 also is darker and more decumbent, its prothorax is less abbreviated 

 and more conical, its elytral ridges are more distinct, its entire 

 sculpture is denser and coarser, and its antennae and palpi are a little 

 more elongated. Like that insect, it is strictly a mountain species ; 

 and the only region in which I have hitherto observed it is the lofty 

 Pinal of Tarajana, above San Bartolome, in the centre of Grand 

 Canary, where, during April 1858, 1 took it, not uncommonly, about 

 the flowers of the Gytisi and Cisti.
