CANABIAN COLEOPTERA. 387 



But, apart from minor characters, I may just add that the present 

 insect may at once be recognized from the B. spinicolHs by its paler 

 or more reddish-brown hue and less hairy (though pubescent) sur- 

 face, by its convexer and more even head and prothorax, larger and 

 more emarginated eyes, and by its antennae being more distant at 

 their base and with their third joint a trifle shorter (instead of longer) 

 than the fourth. Its prothorax, also, is more abbreviated — being 

 truncated at the apex, where its edge is drawn in and subsinuated 

 (instead of being slightly raised and, if anything, somewhat produced). 

 The only example of the 0. pinicola which I have seen was taken 

 by myself, dming the spring of 1858, from within a dried cone of a 

 Pinus canariensis in the island of Palma — high up in the Barranco 

 above S** Cruz. It will probably be found, therefore, to occur gene- 

 rally (though perhaps sparingly) in the Finals of intermediate eleva- 

 tions. It is closely allied to the 0. Nodieri of southern Europe ; 

 but is a little less pubescent ; with its prothorax altogether a trifle 

 narrower, more contracted behind (where the sides are rather 

 straighter, though very oblique), and with the lateral spine shorter 

 and more anyuliform ; and with its elytra almost free from the small, 

 rounded, punctiform, subglabrous spaces which are tolerably evident 

 (and have somewhat the appearance, prima facie, of tubercles) in that 

 species. From the Madeiran 0. Bewichii it may be known by its 

 prothorax being more coarsely punctured, less conspicuously margined 

 along the anterior edge, and with the lateral spine very much shorter 

 and more angidiform, and by its elytra being comparatively free 

 from subglabrous spaces.

Habitat in intermediis Teneriffse et Palma?, rarissimus. 



The European C. rusticus, which occurs in the pine-woods of com- 

 paratively recent introduction on the moimtains of Madeira, is appa- 

 rently rare at the Canaries — though perhaps it might be found more 

 abundantly if the ancient Pinals were diligently searched. Hitherto, 

 however, I have myself met with it only in Palma — where, during 

 June of 1858, I obtained a few specimens at the Banda, on the 

 western side of that island. Nevertheless a Teneriffan example, pur-
