APPENDIX. 



The single specimen from which the above diagnosis has bee 

 compiled was taken by the Messrs. Crotch on the mountains of 

 Gomera, during their late expedition to the Canaries. Although 

 perfectly distinct from them both, it is in some respects intermediate 

 between the L.ellipticus and lepidopterus', nevertheless I think perhaps 

 it is, in reality, nearer to the latter than to the former. From the 

 ellipticus it differs, inter alia, in its broader and less concave rostrum, 

 in its prothorax being wider, much more rounded at the sides, and 

 more deeply punctured, in its elytra being less elliptic (or wider at 

 the base) and beset all over with very elongate erect hairs, and in its 

 antennae being slenderer ; whilst from the lepidopterus it recedes in 

 its less opake surface, in its rather broader rostrum and more pro- 

 minent eyes, in its more deeply and sparingly punctured prothorax, 

 in its differently shaped, (posteriorly more acute) elytra, the erect 

 hairs of which are longer but more remote, and in its more elongated 

 and somewhat paler limbs.

This species has much the general character and sculpture of the 

 L. mendicus, from Hierro ; but it is considerably larger, with its 

 elytra more opake and deeply sculptured, with its scales more ful- 

 vescent (or less cinereous), and with its limbs, and especially the 

 second joint of its funiculus, more elongate. This last feature in- 

 deed would tend rather to affiliate it with the L. obscurus, from 

 Teneriffe ; though its larger bulk, less abbreviated prothorax, more 

 prominent eyes, more opake and deeply sculptured surface, coarser 

 and more fulvescent scales, and longer limbs will equally separate it 

 from that insect. Nevertheless I believe that the L. subopacus 

 (from Gomera), the obscurus (from Teneriffe), and the mendicus 

 (from Hierro), and possibly even the seniculus (from Grand Canary), 



ineis)
