CANARIAN COLEOPTERA. 103 



167. Acrotrichis Matthewsii, n. sp. 



A. breviter obovata, valde convexa, piibescens ; capite prothoraceqvie 

 nigris, hoc lato, augiilis posticis longe productis ; elytris fuscescen- 

 tioribus, apice dihitis truncatis ; antennis pedibiisque testaceis. — 

 Long. Corp. lin. vix i. 



Habitat Palmam, per regiones sylvaticas sub foliis dejectis vulgaris. 



The short, Avide, and convex body of this Acrotrichis, combined with 

 its obovate outline (it being broader in front than posteriorly), the 

 greatly produced hinder angles of its prothora-x, and its fuscescent 

 and apically paler elytra, will sufficiently distinguish it from the other 

 species here enumerated. I may add that it has been examined by 

 the Rev. A. Matthews, who considers it undoubtedly new ; and I 

 have much pleasure, therefore, in naming it after him. It appears 

 (so far as I have observed hitherto) to be peculiar to the island of 

 Palma, throughout the sylvan districts of which it is universal. I 

 have taken it on the ascent to the Cumbre above Buenavista, in the 

 Barranco de Agua, the Barraneo de Galga, and in several other lo- 

 calities. 



168. Acrotrichis fascicularis.

Habitat in Canaria, TenerifFa, Gomera et Hierro, praesertim per 

 regiones sylvaticas, vulgaris. 



This Acrotrichis (which occurs at Madeira) appears to be very 

 abundant throughout Grand Canary, Teneriffe, Gomera, and Hierro, 

 — particularly, however, in the sylvan districts of intermediate ele-. 

 vations. My Teneriffan examples are principally from beneath dead 

 leaves at Las Mercedes, La Esperanza, the Agua Garcia, Ycod el Alto, 

 &c. ; and the Hierro ones from the region of El Golfo. It has also 

 been captured, abundantly, in Gomera, by Dr. Crotch. It is regarded 

 by Mr. Matthews as identical with the common European A. fasci- 

 cularis. It may be known prima facie from the last species by its 

 more oblong outline, comparatively longer and flatter body and less 

 developed prothorax, and by its elytra (except the extreme hinder 

 margin) being almost as black as the rest of the surface ; whilst from 

 the following one its larger size and more produced thoracic angles, 

 in conjunction with its more finely punctured surface and paler an- 

 tennae, will equally remove it.
