3o4 CANARTAN COLEOPTERA. 



to judge from, nevertheless, since they certainly cannot be referred to 

 any of the other species here enumerated, I have ventured to treat 

 them as distinct — believing, in addition, that their mere habitat alone 

 would of itself tend to that conclusion. They were captured near 

 Las Palmas, in Grand Canary ; but whether in the sandy region im- 

 mediately to the north of the town or on the Isleta, I cannot now 

 exactly recall. Judging therefore from the specimens before me, I 

 may add that the L. senimlvs appears to be mainly characterized by 

 the o/w^r^o»s-metallie scales with which it is tessellated, and by its 

 surface being free from erect hairs except at the apex of its (oblong 

 and very deeply punctate-striated) elytra. Its prothorax is most 

 denselj' covered with minute but rather coarse punctules, and has 

 some larger but extremely shallow and distant ones intermixed ; 

 whilst a fine and obscure polished keel is traceable down its disc — 

 more especially behind.

The present Laixirocerus appears to be peculiar to Lanzarote and 

 Fuertcventura — though it is more particularly the former in which 

 I have hitherto observed it, since the single example which I have 

 yet seen from the latter has a few trifling characters of its own in 

 which it differs from the Lauzarotan type ; nevertheless I cannot re- 

 gard them as indicative, at the utmost, of more than a mere insular 

 variety, or phasis, of the species. On the hills above Haria, in the 

 north of Lanzarote, it was taken by Mr. Gray and myself, during 

 January 1858 ; and I subsequently met with it in the same locality 

 during March of the following year. It was likewise captured, by
