new SofUh African Carabidrc. 171 



Nearly related to C. mnrlcijiy Brkr., but a very distinct 

 species. Coinpariiiij the two species " orhicitl'icoUis'^ is more 

 transverse ; the prothorax is wider with the lateral marj^ins 

 more evenly rounded and there is no trace (though it is 

 certainly very obscure in marteiji) of angulation near middle ; 

 the grooves within the reHcxcd margins are less deep, the 

 hind angles are broadly rounded and not sinuately reflexed 

 above. The head is shorter and broader, the puueturation 

 stronger, and there is no smooth space on the vertex, the 

 a'ntennro and palpi are less elongate, the coloration of the 

 legs different, and the ^ <$ are not less ovate than the ? ? , 

 ■whereas in "m«;7ry^" there is a consideral)le difference in 

 in this respect. 



l~)escril)ed fi'om one male and one female example. 



Hab. Salisburv, S. Rhodesia. Collected by the Rev. J. A. 

 O'Neil. 



Chlcenius o'neili, sp. n. 



Length 15 mm. ; width mm. 



Black ; head and prothorax seneous, the former broadly 

 suffused with metallic green frontally, the latter less con- 

 spicuously ^yithin the lateral margins ; outer margins of 

 prothorax, legs, labrum, mandibles, palpi, and three first 

 joints of antennaj reddish testaceous, the remaining joints of 

 the latter deep brown and pubescent. 



Head plane, irregularly, remotely punctate with some 

 inconspicuous plications posteriorly, frontal fovere obsolete, 

 represented by two impressions impinging on the clypeal 

 suture ; palpi sliort, terminal joints gradually widened to 

 apex and abruptly truncated. 



Prothorax transverse, one-fourth wider than long, apex 

 truncate, angles very declivous and briefly rounded : borders 

 at apex narrowly reflexed and grooved, the grooves gradually 

 widening towards and becoming obsolescent above hind 

 angles ; sides gently ampliate to near middle, theucc 

 straightly but with a slight upturned sinuation contracted 

 to the obtuse posterior angles ; base wider than apex, very 

 shallowly emarginate medially, and with some rather long 

 sparse pubescence basally and laterally; disc anteriorly very 

 finely vermiculate, becoming denser towards base and sides ; 

 median line distinct from apex to base, and with a seriate 

 row of punctures on either side of it ; basal foveae broad and 

 deep, rugosely punctate, as well as base between and to 

 angles. 



Elytra oblong-ovate, sparsely pubescent, denser mar- 

 ginally, forming a band, a little wider than prothorax at
