ANOBIAD7E. 



it is to the female sex, therefore, that we must look for the true 

 characters of the species. But even the males of the cylindripennis 

 are usually a trifle broader than those of their more northern ally, 

 and have their elytra rather more decidedly granulated (or still freer 

 from shallow, somewhat longitudinally disposed, subasperated punc- 

 tures). The females however may readily be known from those of 

 the pectinicornis by being paler or more rufescent, whilst their an- 

 tennas are a little darker and have the serrated joints less produced 

 internally ; their pro thorax also is a little more rounded at the sides ; 

 and their elytra are less coarsely alutaceous, and almost free from 

 the rather large though very shallow and irregular punctures which 

 are tolerably evident in that species being merely roughened with 

 comparatively small transversely-subconfluent granules, which tend 

 to merge behind into obscure subasperated punctures. 



650. Ptilinus lepidus. 

 Ptilmus lepidus, Wott., Cat. Can. Col. 251 (1864). 



Habitat Canarienses (Ten., Gom., Palma), in intermediis lignum 

 antiquum perforans. 



A Canarian Ptilinus which 1 have captured at rather low and 

 intermediate elevations in Teneriffe and Palma, where it burrows 

 into old wood principally about houses and in cultivated grounds. 

 A single (dead, and greatly mutilated) example is now before me 

 which was, taken by the Messrs. Crotch, " out of its burrows," in 

 Gomera. Its elytra are rather rougher, and more strongly punctured, 

 than is the case in the Teneriifan and Palman specimens ; but I 

 have little doubt that it represents a mere local, or perhaps insular, 

 state of the lepidus though further material would be desirable, in 

 order to ascertain this for certain. 



The females of the P. lepidus have their entire surface more 

 shining than is the case in the corresponding sex of the Madeiran 

 cylindripennis, as also rather more rufo-ferruginous and quite glabrous 

 (instead of being densely, though delicately, pubescent) ; their pro- 

 thorax is finely punctulated behind (instead of being granulose) ; 

 and their elytra likewise are regularly, though very minutely, punc- 

 tulated (instead of being coarsely alutaceous, and roughened with 

 obscure, somewhat transversely- confluent granules, or shallow sub- 

 asperated punctures), and are apparently without even the faintest 

 tendency to be longitudinally subcostate. The two species, however, 

 are clearly the representatives of each other in their respective Groups.
