20 CANARIAN COLEOPTERA. 



wise taken it between Las Palmas and Puerto da Luz, in Grand 

 Canary. It is in Lanzarote, however, that it more especially abounds ; 

 where it was also captured by John Gray, Esq., and M. Hartung. 



31. Tarus marginellus. 



T. elongatus, nitidus, piceus, calvus ; capite distincte sed parce punc- 

 tulato ; prothorace vix rufescentiore et (in disco saltern) vix pimc- 

 tulato, cordato, angulis ipsis posticis acute exstautibus ; elytris 

 oblongis, subdepressis, crenato-striatis, intorstitiis minutissime et 

 parce punctulatis, limbo anguste rufo-testaceo ; antennis, palpis 

 pedibusque rufo-testaceis. — Long. corp. lin. 3|-4.

 infrequens. 



The comparatively elongate outline and shining, unpubescent sur- 

 face of the present Tarus, in conjunction with its almost unpunctured 

 prothorax (which has its extreme hinder angles acutely prominent), 

 and its rather depressed and finely crenate-striated elytra (the mar- 

 gin of which is narrowly nifo-testaceoxis, whilst the punctules of the 

 interstices are most minute and remote), will at once distinguish it 

 from the thi^ee following species. Hitherto I have observed it only 

 in the north of the island of Lanzarote, where in January 1858 it 

 was ta^en by Mr. Gray and myself (and subsequently, by myself, 

 diu'ing March of the following year), from beneath stones, between 

 the Salinas and the ascent of the lofty cliffs (known as the " Uisco") 

 which rise almost immediately behind them. I have compared it with 

 Brulle's types, in the Paris collection, and can vouch therefore for its 

 being correctly identified with his C. marginella. 



32. Tarus cinctus. 



T. nitidus, piceus, pilis mollibus erectis longiusculis parce vestitus ; 

 capite prothoraceque profunde sed parce punctatis, hoc cordato, an- 

 gulis ipsis posticis vix exstautibus ; elytris ovalibns, subconvexis, 

 levissime striatis, interstitiis profiinde punctatis, limbo anguste 

 rufo-testaceo ; antennis palpisque rufo-testaceis, pedibus testaceis.

Cymindis cincta, Brtdle, in Webb et Berth. (Col.) 55 (1838). 



Habitat in montibus Canariee Grandis, sub lapidibus, rarissimus. 



A remarkable Tarus, at once known by its curious sculpture, — the 

 entire upper surface being impressed with large and deep punctures, 

 whilst the elytral striae are so light as to be almost obsolete. In 

 common with the two following species, it is beset \^'ith very fine and
