Chl^nius consobrinus. 



An intermediate form between C. angustatus and C. cylindricornis , 

 but more nearly related to the former, with which it agrees in colour ; 

 it is, however, more elongated ; the prothorax is a little broader and 

 somewhat more deeply punctured, but the distinctive specific 

 character is found in the shape of the intervals of the striae in the 

 elytra, which are raised, carinated with the ridge smooth, and deeply 

 punctured laterally ; from all these punctures spring short yellowish 

 hairs forming a thick pubescence ; lateral yellow margin as in 

 C. angustatus. Length 14 mm. ; width 5-|- mm. 



Hah. Delagoa Bay (Eikatla). 



Chl^nius cylindricollis, Dej., 

 Spec. Col., v., p. 637. 



Head and prothorax glowing red and bright green on the outer sides ; 

 labrum, palpi, antennae, and legs yellowish; head nearly smooth; 

 prothorax of the same shape as in G. angustatus, but slightly longer, 

 and with the same sculpture ; elytra broader than the prothorax, 

 elongated, narrowly punctato-striate, with the intervals smooth, 

 hardly raised, dark bottle-green, a little lighter laterally, and with a 

 marginal yellow band encroaching on the eighth interval, where it 

 reaches nearly the seventh stria, and broader behind, where the 

 upper edge of the posterior band is dented and invades the apical 

 part of the striae ; under side black, moderately shining ; abdomen 

 narrowly marginated with yellow. 



Examples from Delagoa Bay (Eikatla) and Middle Limpopo have 

 the elytra and also the median part of the prothorax greener than in 

 the Natal and Cape Colony specimens. Length 13-16 mm. ; width 

 5J-6 mm. 



Hah. Cape Colony (Grahamstown, Somerset East), Natal, 

 (Maritzburg), Delagoa Bay (Eikatla), Zambezia (Middle Limpopo 

 Eiver). 



Closely allied to both the preceding species, but differentiated by 

 a somewhat more elongated body, although G. consohriuus is a form 

 of transition in that respect between G. angustatus and the present 

 species, and also by the dilatation of the yellow margin in the pos- 

 terior part. 



Chl^nius angustatus, Dej., 

 Spec. Col., v., p. 637. 



G. cinctipennis , Bohem., Insect Caffr., i., p. 148. 



Head and prothorax bright green with a coppery tinge in the 

 centre ; labrum, palpi, antennae, and legs pale yellow ; head and pro- 

 thorax nearly smooth, the latter narrow, a little attenuated laterally in
