CANARTAN COLEOPTERA. 307 



same breadth posteriorly as the base of the elytra), but it is also more 

 opake, densely clothed, except on the hinder disc of its elytra, with 

 large, robust, snowy- white scales (which moreover are flattened, and 

 closely applied to the surface, instead of being narrow and piliform); 

 the female rostrum is verij much slenderer, brighter, paler, and com- 

 paratively unsculptured, as well as a little longer and more arcuated ; 

 its eyes are less widely separated, which causes the forehead to be 

 narrower ; its elytra are entirely pale, except the suture ; its legs are 

 shorter, robuster, and squamose ; and its antenna) are considerably 

 slenderer and of a moi'e paUid hue. The only two specimeiis which 

 I have seen were captured by myself on the mountains above S'" Cruz, 

 in the island of Palraa, during May 1858.

This common European insect, which occurs also (though sparingly) 

 in Madeira, appears to be extremely local at the Canaries. It wns 

 taken by Mr. Gray and myself, from off nettles, near the Puerto Oro- 

 tava of Teneriffe, during January 1 858 ; and during the following 

 month, by myself, in Hierro.

Habitat in TenerifFa, Palma et Hicrro, hinc inde baud infrequens. 



The A. delicatulum (which I first detected in the north of Madeira, 

 during August 1855) is widely spread, though apparently nowhere 

 common, over the Canarian Group. I have taken it near the Puerto 

 Orotava and Souzal, in Teneriffe (in the former of which localities it 

 was also captured by Mr. Gray) ; as well as in the Barranco da Agua 

 of Palma, and in Hierro. In Teneriffe it was likewise met with by 

 Dr. Crotch. It may be known from the A. vernale by its rather longer 

 and a little more arcuated rostrum (which is of the same breadth 

 throughout, and is oiot widened at its extreme base, behind the inser- 

 tion of the antennte, and which, moreover, is minutely alutaeeous 

 when viewed beneath a high magnifying power, instead of shining 

 and distinctly punctulatcd); by its elytra being a trifle more ovate (or 

 more expanded behind the middle), and less evidently subrecurved,
