CANARIAN COLEOPTERA. 509 



very porrect (causing the anterior margin, when viewed from above, 

 to appear as though deeply bisinuated), the basal ones more or less 

 right angles, and the sides not much rounded, will serve to distinguish 

 it. It was taken sparingly by Mr. Gray and myself, during January 

 1858, near Haria, in the north of Lanzarote ; and again, by myself, 

 in the spring of 1859, in the same district. 



761. Helops aethiops, n. sp. 



H. praecedenti similis sed ad staturam minorem descendens, saepius 

 obsoletissime (vix perspicue) subajneo-tinctus ; oculis vix majo- 

 ribus ; prothorace subconvexiore, ad latera magis rotundato, an- 

 gulis anticis minus porrectis, posticis obtusioribus, vix parcius pro- 

 fundiusque punctato, per basin minus arcuato-truncato ; elytrorum 

 iuterstitiis plerumque etiam subminutius punctulatis. — Long. corp.

Habitat Lauzarotam et Fuerteventuram, sub lapidibus, passim. 



In the large size of at any rate the larger examples, deep-black 

 hue, and shining surface, this species is at first sight scarcely separable 

 from the preceding one; nevertheless it appears to descend to a 

 smaller stature than that insect, and the shape of its prothorax is ex- 

 ceedingly different — being somewhat convexer and less quadrate, 

 with the sides rounder, the anterior angles less porrect, the posterior 

 ones more obtuse, and its basal edge rather less arcuated. Its eyes 

 are a trifle more developed (or longitudinally broader); its prothorax 

 is, if anything, a little less closely and more coarsely punctured ; the 

 punctules of its interstices are, if possible, even still more minute ; 

 and its surface has very often a just perceptible senescent tinge. It 

 seems to be confined to Lanzarote and Fuerteventura, in both of which 

 I have taken it, though especially the latter (where it was likewise 

 found by Mr. Gray and M. Hartung). My Fuerteventui'an specimens 

 are chiefly from the vicinity of Puerto de Cabras and Oliva ; and I met 

 with it even on the little island of Lobos, in the Bocayna Strait. 



762. Helops picescens, n. sp. 



£r. fusco-piceus, minus nitidus ; capite prothoraceque densissime 

 punctatis, hoc ad latera suba;qualiter rotundato (ante angulos 

 posticos obtusiusculos hand sinuato) ; elytris tenuiter punctato- 

 striatis, iuterstitiis minutissime punctulatis ; antennis pedibusque 

 plus minus clare rufo-ferrugineis. 



Variat in Fuerteventura prothorace vix levins parciusque punctato.
