CANABIAN COLEOrTEEA. 101 



scutellum being larger ; and by its elytra being perceptibly rounder, 

 or less acute, (and more rufescent) behind, more obliquely lopped-off 

 at their humeral angles, and furnished with an evident (though ante- 

 riorly evanescent) sutural stria on each. Apparently, too, it is a trifle 

 larger than the ghhulam. In its anteriorly unemarginated prothorax 

 it would seem almost to merit generic separation ; nevertheless its ex- 

 ternal features are so i)recisely those of an Ar/athidium that, until 

 further material has been obtained, and its limbs and mouth have 

 been carefully examined, I am unable to pass any opinion on its 

 purely structirral details.

164. Clambus complicans, n. sp. 



C. breviter ovalis, nitidissimus, impunctatus, fere glaber (pilis bre-

 tiusculis ; antennis pedibusque pallide testaceis, illarum clava ob- 

 scuriore. — Long. corp. lin. vix |^. 



Habitat in Canaria, Teneriffa et Gomera, sat rarus. 



The present Clambus is larger than any of the few European species 

 which have hitherto been detected ; and it is fiu'ther remarkable for 

 its more or less rufescent head and prothorax (the latter of which has 

 its edges broadly paler and subpellucid), for the excessively short, 

 minute, and remote pile with which it is sparingly beset, for its eyes 

 being small and considerably removed from the margin of the head 

 (the lateral angle of which is not quite so acute as in the ordinary 

 Clambi), and for its very pallid limbs. It appears to be rare, — the 

 only spots in which I have myself observed it being in the region of 

 El Monte in Grand Canary, and at Las Mercedes and the Agua Garcia 

 of Teneriffe. Specimens, however, have been taken by Dr. Crotch both 

 ia the latter island and in Gomera. It is scarcely possible, I think, 

 that it can be a geographical modification of any of the more northern 

 members of the genus.
