Habitat in intermediis TeneriffaB, a DD. Crotch ad Ycod el Alto capta. 



A remarkable species, which, was taken by the Messrs. Crotch 

 (rather abundantly), during their late Canarian campaign, at Ycod 

 el Alto in Teneriffe. It is at once conspicuous for its very large, 

 broad, convex, laterally rounded, and deeply and closely punctured 

 prothorax, and for its elytra being more or less brightly (though 

 gradually) diluted in hue, or rufo- testaceous, towards their base. It 

 varies, however, a good deal in the intensity of its colouring, some 

 examples (particularly immature ones) being altogether reddish- 

 ferruginous. Its antennae, likewise, at any rate of the males, are 

 longer than is the case in the ordinary Atomarice. 



Atomaria venusta, n. sp. 



A. ovalis, parce sed distincte punctata, nitidissima et pube minutis- 

 sima brevissima albida parcissime irrorata ; capite prothoraceque 

 rufis, hoC subconico, basi vix constricto sed in media parte profunde 

 transversim impresso ; elytris convexis, nigris, ad apicem interdum 

 paulo dilutioribus ; antennis crassis, rufo-ferrugineis ; pedibus 

 rufo-testaceis. Long. corp. lin. |-. 



Habitat Gomeram, a DD. Crotch in intermediis lecta. 



Obs. A. rubricolli statura, colore habituque general! affinis, sed 

 nitidior, minus pubescens (fere pube carens) ac minus dense et 

 paulo minus profunde punctata ; prothorace subangustior, minus 

 transverse, magis conico, ad latera minus rotundato et minus crasse 

 marginato, per basin minus constricto, sed in media parte eviden- 

 tius profundiusque transversim impresso. 



Taken in Gomera, during the summer of 1864, by the Messrs. 

 Crotch. It is strictly the representative in that island of the Tene- 

 riffan A. rubricollis, which indeed in general colour and aspect it 

 so nearly resembles that at first sight it might almost be mistaken 

 for it. When closely inspected, however, it will be seen to possess 

 many characteristics of its own, which remain perfectly constant in 

 every specimen I have examined ; and I have not the least doubt, 

 therefore, that it is truly distinct from its Teneriffan ally. Thus, it 

 is more highly polished, much less pubescent (there being scarcely 

 any appearance of clothing at all except when viewed beneath the 

 microscope), and less densely and rather more finely punctured ; and
