CANARIAN COLEOPTERA, 561 



punctulcs at the base of its pronotum (which are not situated quite 

 upon the edge itself), and its more numerously punctiu'ed three ely- 

 tral lines, will at once separate it from the B. luridus. In general 

 colouring, size, and aspect it is scarcely distinguishable, prima facie, 

 from the Mi/cetoporus soUdicornis ; nevertheless, on a closer inspec- 

 tion, the last joint of its maxillary palpi will show it to be a true 

 Bolitohins ; and its antenna? are very much longer, more filiform, 

 and less compact. When accurately examined it will be further seen 

 to be altogether a trifle narrower and less elliptic, with its abdomen 

 more piceous (or less black), its limbs a Httle paler, and its four an- 

 terior prothoracic punctules placed considerably nearer to the front 

 margin. 



Like the B. luridus, the present species seems to be very rare, and 

 to be confined to intermediate elevations — occurring, however, in sub- 

 sylvan as well as sylvan spots. I have taken it in the region of El 

 Monte in Grand Canary, as well as in Hierro ; and a single example 

 is now before me which was found by Dr. Crotch in Teneriffe.

Although the large size and excessively abbreviated, roughly sculp- 

 tured elytra of this fine StaphyUnid might be supposed at first sight 

 to assign it to a genus distinct from (however nearly aUied to) Eury- 

 porus, nevertheless the various details of its structure do not appear 

 to me (when carefully inspected) to present sufficient peculiarities to 

 warrant its isolation. Indeed in most of its essential features — such 

 as the approximation of its intermediate coxae, its deeply incised 

 upper lip, its filiform maxillary palpi and the securiform last joint of 

 its labial ones, the shape and proportions of its mcntuni, ligula, and
