27C? CANARIAN COLEOPTERA. 



it would aj)pear to be very rare, two examples only, both of them 

 from Teneriffe, having as yet come beneath my notice, — one of which 

 I captured in a house immediately above the Puerto of Orotava, 

 during March 1858, whilst the other was found by the Eev. R. T. 

 Lowe, during April 1860, in a dead Euphorbia -stem, at Garachico. 

 Its convex, fusiform body, ajneous hue, and shining, lightly sculp- 

 tured surface, in conjunction with its obsolete eyes and 5-jointed 

 funiculus, will, apart from numerous secondary characters (fully 

 pointed out in my diagnosis), sxifRce to distinguish it.

In my Paper on the Cossonides I have stated that '' the present 

 large and beautiful Mesites (which, so far as I have hitherto ob- 

 served, appears to be peculiar to the island of Palma) may be known 

 readily from the following one by its broader outline, more depressed, 

 deeply sculptured surface, and darker hue. Its prothorax is wider, 

 and more rounded at the sides, than is the case in that iiisect, with 

 its punctures considerably larger and less dense, and its central keel 

 more evident ; whilst its elytral striae are much deeper, wider, and 

 more coarsely crenated, and the interstices proportionally narrower 

 and more costate. I took it, not uncommonly, beneath the loose 

 bark of the native laurels, in the dense sylvan ravines of Palma, at 

 rather a high elevation — especially the Barranco da Agua and the 

 Barranco de Galga — during May and June of 1858." 



445. Mesites persimilis. 



Mesites persimilis, Woll, Tram. Ent. Soc. Loud. v. 402 (1861). 



Habitat in locis similibus ac prsecedens,sed in TenerifFa (nee Palma). 



" The M. persimilis, which abounds in certain spots within the 



sylvan regions of Teneriflfe, is narrower, less depressed, more piceous, 



and (on the average) rather smaller than its Palman representative 5 



its prothorax, also, is less rounded, or widened, at the sides, more 



closely and less deeply punctured, and with its central keel less dis-
