CANAEIAN COLEOPTERA. 125 



&c., in the thickest and dampest parts of the forest. I have taken 

 it at the Agiia Mansa, Ycod el Alto, the Agna Garcia, Las Mercedes, 

 and on the sylvan slopes ahove Taganana and Point Anaga. 



207. TarpMus camelus. 

 Tai-phius camelus, JFolL, loc. cit. 383. pi. 19. f. 2 (1862). 

 Habitat ins. Hierro, in sylvaticis occidentalibus regionis "El GoKo" 

 dictae, mense Februario a,d. 1858, repertus. 



The only two specimens which I have seen of this fine Tarphius 

 were captured by myself, during February 1858, in the island of 

 Hierro — in the dense sylvan region which forms the upper part of 

 the district of El Golfo. 



208. Tarphius canariensis. 

 Tai-phius canariensis, Woll, loc. cit. 383. pi. 19. f. 3 (18G2). 



Habitat Canariam, TenerifFam et Palmam, in sylvaticis sat vulgaris. 



The present Tarphius is apparently more widely spread over the 

 archipelago than any of the other species here enumerated. In the 

 wooded districts of Teneriffe it is universal — occurring, in similar 

 spots as its allies, at the Agua Mansa, the Agua Garcia, Ycod el Alto, 

 Las Mercedes, Taganana, &e. ; and I have likewise taken it, though 

 sparingly, at Osorio in Grand Canary, and (more abundantly) in the 

 various sylvan regions of Palma. The examples from the latter island 

 are just perceptibly narrower and less flattened than those from Tene- 

 riffe, and have their setae a trifle longer, darker, and less thickened, 

 their prothorax a little more seooped-out behind, their elytral nodules 

 but seldom diluted in hue, and their antennae perhaps (if anything) 

 somewhat shorter ; but I do not believe that they can be regarded 

 as specifically distinct. I have, however, in my paper already alluded 

 to, recorded them as a " var. /3 " of the T. canariensis. 



209. Tarphius erobus. 

 Tarphius erosus, Woll., loc. cit. 384. pi. 19. f. 4 (1862). 



Habitat in sylvaticis Teneriffae, una cum specie praecedente degens. 



It is just possible that this Tarphius may be but an extreme state 

 of the T. canariensis, in which the prothorax is much more suddenly 

 and deeply scooped-out behind than is the case in the ordinary type ; 

 nevertheless, since I have not been able to connect it with that in- 

 sect, I think it would scarcely be safe to treat it as such, — more 

 particularly since it possesses other minute distinctions of its own 

 (which are fully pointed out in my " Notes on the Taiphii " already
