506 CANARIAN COLEOPTEBA, 



always readily separable, at first sight, from the smaller ones of that 

 insect. Nevertheless I believe it to be truly distinct — differing from 

 it in its less intensely black hue (which is occasionally even subpi- 

 cescent), and in its less shining and less coarsely sculptured elytra, 

 the strioe of which are hoiYi. Jinet' and more lightly impressed, whilst 

 the interstices (which are generally rather flattened, and but sHghtly 

 rugose) are so minutely punctulated that the punctules are often 

 barely traceable. Its prothorax is a trifle longer, and convexer an- 

 teriorly, though somewhat more lateraUy -compressed on either side 

 before the posterior angles, its front angles are appreciably acuter and 

 more porrect, and the punctures on its disc are usually smaller and less 

 deep. The specimens from Palm a and Hierro have their prothorax 

 almost ^insinuated at the sides (in front of the basal angles), and their 

 elytra usually a little more coarsely sculptured. 



756. Helops aterrimus, n. sp. 



//. affinis H. carhunculo, sed aterrimus, nitidissimus ; prothorace ad 

 apicem quasi profundius bisinuato (angulis anticis valde et acute 

 porrectis), in disco levius subtiliusque sed versus latera densius 

 punctato ; pedibus masculis sensim crassioribus. — Long. corp. hn. 

 4-5^. 



Habitat Gomeram, sub lapidibus prope Sanctum Sebastianum vul- 

 garis. 



This is the common HeJops around, and above, San Sebastian in 

 Gomcra — where it was taken by Mr. Gray and myself, from beneath 

 stones, during February 1858. It may be known by its intensely 

 black hue and highly polished siu'face ; by its prothorax being lightly 

 and finely punctured on the disc, but densely and coarsely so at the 

 sides, with the anterior angles very porrect and acute (which causes 

 the apical edge, when viewed from above, to appear as though deeply 

 bisinuated) ; and by the thickness of its male legs. 



757. Helops nitens, n. sp. 



H. breviusculus, obsoletissime submetallico-ater, nitidissimus ; capite 

 prothoraeeque dense et profundc punctatis, hoc ad latera ante an- 

 gulos posticos argute obtusiusculos vix sinuato ; elytris leviter cre- 

 nato-striatis, interstitiis depressis, minutissime punctulatis ac paulo 

 transversim rugulosis, versus apicem obsolete seriatim tuberculatis ; 

 antennis pedibusque la^te rufo-piceis. — Long. corp. lin. vix 4. 



Habitat Teneriff'am, a W. D. Crotch semel repertus. 



A single example of this Helops was taken by Dr. Crotch in Tene- 

 riff"e (I believe, above Ycod el Alto), during the spring of 1862. It 

 has somewhat the shajie of (though a Uttle broader and shorter than)
