deeply punctured, and the intervals of the elytra are convex ; under 

 side piceous, iridescent. Length 12-12^ mm. ; width 5-6 mm.

Black, opaque on the upper side, piceous and slightly iridescent 

 underneath ; palpi, antennae, and legs reddish ; head smooth in the 

 centre, aciculated behind ; labrum faintly reddish ; prothorax sub- 

 trapeziform, a little attenuated towards the base, covered with 

 minute closely-set punctures and briefly pubescent ; elytra a little 

 broader than the prothorax at the base, elongated, narrowly 

 punctato-striate, with the intervals plane, very finely shagreened 

 and with a dense, very short pubescence. Length 12-1 2 J mm. ; 

 width 5 mm.

Chl^nius piceus, Chaud., 

 Monogr., loc. cit., p. 165. 



Black, moderately shining, or subopaque ; palpi, apical part of the 

 labrum, legs, and the three basal joints of antennae yellowish red ; 

 the other joints rufescent, and the tarsi infuscated, under side very 

 iridescent ; head faintly aciculated ; prothorax with the outer sides 

 nearly straight but slightly narrower at the apex than at the base ; 

 plane on the disk but slightly declivous in front and covered with 

 closely-set, moderately deep, conspicuous punctures, and hardly 

 pubescent ; elytra fitting against the base of the prothorax, nearly 

 parallel, narrowly punctato-striate, with the intervals almost plane,_ 

 shagreened and almost non-pubescent. Length 12-14 mm. ; width 

 4^5 mm. 



^Hah. Cape Colony (Port St. John), Natal (D'Urban). 

 Easily distinguished from G. dichrous by the more trapezoid 

 shape of the prothorax, the punctures of which are also much more 

 pronounced, the elytra are more parallel, the intervals more roughly 

 shagreened and the striae deeper.

Colour, shape, and size of C. piceus, but is more shiny on the 

 upper part ; the sculpture of the head and prothorax is identical, 

 but the elytra, which in piceus, are slightly ampliated outwardly 

 at a short distance from the humeral angle are here quite straight,
