799. Auletes anceps. 



Auletes anceps, Wott., Cat. Can. Col. 305 (1864). 

 Habitat Canarienses (Hierro), hactenus parcissime deprehensus. 



Two examples of this Auletes, taken by myself in Hierro of the 

 Canarian Group, are all that I have yet seen ; and although they 

 appear really to differ (even though slightly) both from the preceding 

 species and the following one, further material must decide whether 

 it be possible to regard them as representing any insular phasis of 

 those insects. 



In some respects indeed the A. anceps is intermediate between the 

 cylindricollis and convexifrons, though (so far as I can judge from 

 merely two individuals) I do not think that it would be safe to treat 

 it absolutely as a mere state of either of them. It differs from the 

 former in being of a paler hue, with its punctation altogether a little 

 denser and less coarse, in its rostrum being rather longer and more 

 lightly punctured, in its eyes being just perceptibly smaller, in its 

 prothorax being a trifle more expanded behind (or less cylindrical), 

 in its elytra being more elongated and less shining, in its antennal 

 club being perhaps (if anything) more abruptly denned, and in the 

 basal joint of its feet being somewhat shorter ; whilst from the latter 

 it recedes in its rostrum being longer, in its prothorax being less 

 abbreviated and less rounded posteriorly, in its forehead being less 

 convex, and in the last joint of its clava being rather less conical or 

 acute. Of the two species, I think perhaps that it is more allied to 

 the convexifrons than to the cylindricollis. 



800. Auletes convexifrons. 



Auletes convexifrons, Wall, Cat. Can. Col. 305 (1864). 



Habitat Canarienses (Can., Ten., Gom.}, in locis similibus ac A. cy- 

 lindricottis. 



Likewise a Canarian Auletes, and found amongst herbage in the 

 intermediate districts. I have captured it in Grand Canary and 

 Teneriffe, and it was taken by the Messrs. Crotch in Gomera. 



801. Auletes maderensis. 



Auletes Maderensis, WolL, Ins. Mad. 416, tab. viii. f. 7 (1854). 

 , Id., Cat. Mad. Col. 122 (1857). 



Habitat Maderenses (Mad.}, in herbidis intermediis haud infrequens. 



Widely spread over the intermediate elevations of Madeira proper,
