Metallic green on the upper part, excepting the labrum, epistoma, 

 antennae and palpi, which are black ; head slightly punctulate in 

 the centre ;, prothorax nearly as long as broad, a little broader in 

 the anterior part than behind and faintly plicate ; elytra sub-

Hah. Cape Colony (East London), Transvaal (Leydenburg) . 



Peomecochila nigra. 



Totally black, shining ; head very slightly punctulate ; prothorax 

 with the outer sides nearly straight for three-fourths of the length, 

 the anterior angles slightly rounded and very faintly plicate ; elytra 

 subparallel, deeply striate, with the intervals plane and very finely 

 aciculate. Length 5 mm. ; width 2|- mm.

Hah. Natal (Erere). 



Gen. MATABELE. 



Mentum broadly emarginate, with the median part subdentate, 

 inner part of the lateral lobes nearly straight, ampliate in the middle 

 outwardly, the apical part slightly oblique ; ligula horny, subrounded 

 at the tip and bisetose ; the paraglossse united with it, equally broad 

 but a little shorter, the apical part plurisetose and slightly oblique ; 

 last joint of maxillary and labial palpi subcylindrical, a little attenuate 

 at the tip, which is truncate ; labrum moderately long, longer than 

 broad ; head straight, eyes very prominent ; prothorax rounded in 

 the anterior part, straight from there to the posterior angle, median 

 part of the base produced behind ; elytra elongato-quadrate, nearly 

 plane, deeply sinuate in the apical part, with the posterior angle very 

 sharp and projecting ; legs moderately long ; tibiae deeply grooved 

 in the inner upper part ; last joint of tarsi deeply incised ; claws 

 pectinate, with nine teeth on each side. 



The shape of the mentum, ligula, and paraglossae is almost the
