50 On new Species of South-African Carabide. 
identical, judging by the description of the former and 
comparing it with three specimens of the latter in my 
possession. Chaudoir’s description of his species, though 
somewhat confusing, evidently apples to my examples, 
which all have the two distinctive infuscated thoracic bands, 
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 think it is highly probable that Chaudoir’s 
insect will turn out to be a mere variety or at most a sub- 
species of Boheman’s elegans. 
Tribe PLATYNINI. 
Platynus (Agonum ?) suturalis, sp. n. 
Length 74 mm.; width 3 mm. 
Head, neck, and palpi deep reddish brown; prothorax 
testaceous red, margins paler; antennze, 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 diffused from above the 
declivity. 
Head faintly longitudinally aciculate with a hardly per- 
ceptible median sulcus. -dntenne long, slender, joints with 
the exception of the second of even length. 
Prothorax 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 simuate and having a little above 
it a narrow sulcus which reaches the lateral marginal 
grooves on either side ; dise shining, convex, almost imper- 
ceptibly transversely aciculated and with a narrow median 
groove from apex to base. 
Elytra one-third wider than prothorax, shoulders broadly 
rounded, sides very gently ampliated to beyond middle, 
rounded and a little sinuated to apex ; strize 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, postmedian and subapical 
respectively. 
In size and general outline it is not unlike P. velox, Pér., 
but the prothorax is much wider and rounder and the Iegs 
are shorter. 
In colour and markings it is very distinct from any of 
the South-African members of the genus known to me.
