138 Mr. T. V. WoUaston on certain Coleopterous Insects 



quadrate ; elytris leviter striato-punctatis, pallido-testaceis sed ad 

 apicem (necnon plerumque etiam per suturam et circa scutellum) 

 nigi-o-infuscatis ; pygidio valde retecto, nigrescente ; autennis piceo- 

 ferrugineis ; pedibus piceo-testaceis.

The naiTow outline, smaller size, more shiaing siu'face and shorter 

 elytra of the M. tricolor, in conjunction with its totally different 

 colour — the head, prothorax and abdomen being dark, with the 

 elytra (which, however, have their scutellaiy and apical regions 

 more or less darkened also) pale-testaceous, and the limbs piceo- 

 testaceous, — vnR readily separate it from the foregoing species. As 

 already stated, it was found by Mr. Bewicke in company with the 

 31. 2>attiduni. 



Fam. Cryptophagidae. 



Genus Atom aria. 



(Kby.) Steph., lU. Brit. Ent. iii. 64 (1830). 



Atomaria Capensis, u. sp. 



A. ovata, convexa, pallido-castanea, pares pubescens, nitida, profunde 

 sed remote punctata ; prothorace transverso-subquadi-ato, ad latera 

 paido rotuudato et ibidem distincte marginato, postice subtruucato, 

 margiue in media le^dter elevato ; elytris ad apicem ipsum vix pygi- 

 dium tegentibus ; antennis fusco-piceis, clava obscuriore ; pedibus 

 infuscato-testaceis.

Two examples of this little Atomaria were captured by Mr. 

 Bewicke at the Cape of Good Hope, but imder what ciixumstances 

 I cannot saj'. It is very nearly akin to the common European 

 A. apicalis, but certainly distinct therefrom., — as will be readily 

 seen when the species are placed alongside each other beneath the 

 microscope. It is of a more palhd-castaneous hue, and of a rather 

 more ovate (or less elliptic) form ; its punctation is deeper and 

 more distant, its surface less pubescent, its prothorax is less drawn- 

 in anteriorly (being a trifle more rounded at the sides and of almost 

 equal breadth before and behind), rather more truncated at its base, 

 and more evidently margined (particularly at the lateral edges), its 

 elytra are not quite so ample at their extreme apex (where they do 

 not cowpletehj conceal the pygidium), and its limbs (especially the 

 aiiteuual club) are altogether darker.
