350 CANARIAN COLEOPTERA. 



seem, therefore, to be the representative in that island of the Tene- 

 rifFan L. mce.qtiaUs ; for I think it would certainly be unsafe to treat 

 it as an insular modification of the same. It may be known from 

 its ally by the altogether darker colour both of its surface and clothing ; 

 and by its elytra being a little rounder or more ventricose, with the 

 punctures of their striae considerably larger, the hairs with which 

 they are studded somewhat longer, softer, and less fulvescent, and 

 with their alternate interstices less conspicuously imdulated with ob- 

 tuse tubercles — the tubercles themselves being not only less elevated, 

 or defined, but also less clothed (and more darkly so) with decum- 

 bent scales.

The unique example from which the above diagnosis has been 

 compiled was captured by myself, during February 1858, from amongst 

 vegetation on some wet rocks at a lofty elevation in the island of 

 Hierro — namely, on the wooded mountains above the district of El 

 Golfo. It may readily be known by its large size and only slightly 

 shining, obscure- (though scarcely brownish-) black surface ; by its 

 rostrum being somewhat flattened, and with the channel not much 

 impressed ; by its prothorax being regularly, evenly, and deeply punc- 

 tured, with the minute intermediate punctules close and distinct ; by 

 its elytra being thick, oval, and convex (the alternate interstices not 

 being tubercled as in the three preceding species) ; by its antennae 

 and legs (particularly the posterior pair) being rather short and ro- 

 bust (the former, also, having their scape a good deal curved) ; by 

 its scales being of a dull brownish-metallic hue ; and by its surface 

 being free from additional erect hairs, though beset on the elytra 

 (especially behind) with excessively abbreviated and minute decum- 

 bent seta;. The L. occidentalis, gJohtdipennis, inaqualis, and hirttis, 

 although most distinct inter se, belong to much the same fy2^e ; and 

 perhaps the oht riangularis might be included with them.
