58 CANARIAN COLEOPTERA. 



In its external contour this insect approaches so near to the ordi- 

 nary Harpali that, were it not for its slightly enlarged head and 

 anterior tibial spurs, and (still more) for the difficulty (indeed almost 

 the impossibility) of placing it in a different group from the preceding 

 species, it could scarcely have been regarded as a Cratognathus : never- 

 theless I am satisfied that to detach it from its allies on account of 

 lis prima facie aspect would be most unnatural ; and it must therefore 

 remain as a small, and not very typical, member of the present genus. 

 It is at once chai'acterized by its darker (or less piceous) hue, by the 

 more acute (in fact almost minutely-prominent) hinder angles of its 

 prothorax, and by the very opposite appearance of its sexes, — the 

 males being shining (though less so than in any of the foregoing 

 species), with their elytra very deeply striated and the interstices 

 convex ; wliilst the females are nearly opake, with their striae light, 

 and their interstices depressed. The only two examples which I 

 have seen were taken in the sylvan region above Taganana, of Tene- 

 riflfe, during May 1859.

Habitat in Lanzarota, Fuerteventura et Palma, sat rarus. 



The European H.tenehrosus (which occurs also in Madeira and Porto 

 Santo) is found sparingly throughout Lanzarote and Fuerteventura ; 

 and I have also taken it in the Banda, on the west of Palma. Although 

 a well-known insect, I have given a diagnosis of it in order to point 

 out its distinctions from the following species.

H. niger ; prothorace brevi, transverse subquadrato, ad latera postice 

 subrecto, angulis posticis subrectis, basi utrinque parce sed pro-
