1896.] of the Coleoptera of South Africa. 513 



laterally in the middle, and very little sinuated behind, smooth, with 

 a few scattered punctures ; elytra elongated, subparallel, narrowly 

 punctato-striate, with the intervals convex, carinated, nearly hairless, 

 greenish black on the dorsal part, green on the sides, and with a 

 yellow marginal band reaching from base to apex and extending as 

 far as the eighth stria ; under side piceous, iridescent ; abdomen 

 marginated with yellow. Length 16 mm. ; width 7 mm. 



This species is not unlike G. cylindricollis , but it is more rol^ust, 

 the prothorax is much broader and the costae on the elytra are more 

 raised. In general facies and also in colouring it resembles G. 

 (Epomis) circumscriptics , but the last joints of the palpi of the male 

 are cylindrical, instead of being securiform as in G. capensis. Length 



16 mm. ; width 7 mm.

Closely allied to G. cajncola, from which it differs in the shape of 

 the prothorax, the outer sides of which are straight from the base 

 to four-fifths of the length, whereas in capicola they are a little 

 narrowed and slightly sinuate from the median part towards the 

 base ; the head and prothorax are duller green, darker on the elytra. 

 In general facies this species is also closely connected with G. 

 (Epomis) circumscriptus, but the same remarks on the shape of the 

 prothorax holds also good here, and the elytra have nearly plane 

 intervals instead of carinated ones as in circumscriptiis. Length 



17 mm. ; width 6J mm. 



The only example of this species I have seen is one of Chaudoir's 

 types, collected by De Castelnau, and very kindly communicated by 

 Dr. Gestro of the Genoa Museum. 



Chl^nius mendax, Chaud., 

 Monogr., loc. cit., p. 133. 



Also a very close ally of G. capicola, but much broader and longer ; 

 the prothorax is shorter in proportion, the colour of the head and 

 prothorax is brighter green, and only the median part of the elytra 

 is dark green, while the sides are brighter. Length 19-|- mm. ; width 

 8 mm.

Head and prothorax bright green ; labrum, palpi, and legs 

 yellowish red ; head closely punctulate ; prothorax hardly ampliated
