50 On new Species of South- African Carnblclffi. 



identical, judging by the description of tlie former and 

 conijjaring it \>itli three si)ecinieus of the latter in my 

 possession. Cliaudoir's description of his species, though 

 somewhat confusing, evidently applies to my examples, 

 uhieh all have the two distinctive infuseated thoracic hands, 

 though there is only the faintest trace of the frontal spot, 

 and then in one specimen only. The elytral pattern, which 

 varies a good deal between evanescence and extra develop- 

 ment of some of the spots is arranged exactly as in 

 C. elegans, and I tiiink it is highly probable that Cliaudoir's 

 insect will turn out to be a mere variety or at most a sub- 

 species of Bohemau's elegans. 



Tribe P l a t y x i n i . 

 Platynus i^Agonum ?) suturalis, sp. n. 

 Length 7\ mm. ; width 3 mm. 



Head, neck, and palpi deep reddish brown; protliorax 

 testaceous red, margins paler; antenn.'o, legs, and beneath 

 reddish testaceous : elytra brownish testaceous with dorsally 

 two obscurely defined fuscous bands covering the intervals 

 3 and 4 and reaching from below shoulders to near 

 apices, but becoming somewhat ditiused from above the 

 declivity. 



Head faintly longitudinally aciculate with a hardly per- 

 cepti])le median sulcus. AntenncB long, slender, joints with 

 the exception of the second of even length. 



Frothorax orbicular, a little wider than long, emarginate 

 in front, declivous and sharply rounded at angles, lateral 

 margins broadly reflexed, evenly rounded from apex to base, 

 no posterior angles, base sinuate and having a little above 

 it a narrow sulcus which reaches the lateral marginal 

 grooves on either side ; disc shining, convex, almost imper- 

 ceptibly transversely aciculated and with a narrow median 

 groove from apex to base. 



Elytra one-third wider than protliorax, shoulders broadly 

 rounded, sides very gently ampliated to beyond middle, 

 rounded and a little sinuated to apex ; strife faintly punctu- 

 late, intervals plane and smooth, with three punctures on 

 the third interval, the first a little below base, the second 

 and third somewhat near together, postmediau and subapical 

 respectively. 



In size and general outline it is not unlike P. velox, Per., 

 but the prothorax is much wider and rounder and the legs 

 are shorter. 



In colour and markings it is very distinct from any of 

 the South-African members of the genus known to me.
