Gymnopleueus virens, Erichs., 

 Wiegm. Arch., 1843, i., p. 231. 



G. sniaragclinus, Fahr. pars. Insect. Caffrar., ii., p. 187. 



Bright metallic green, sometimes bluish green, and occasionally 

 green with a brassy tinge, clothed like G. ignitus, with a silky white 

 pubescence on the sides of abdomen and the outer part of the 

 posterior femora ; head shaped and sculptured as in G. ignitus ; the 

 prothorax is similar in shape, but it is moderately closely punctured 

 on the greatest surface of the disk, the curved patch and areolet on 

 the sides are not raised, and as often as not are quite obliterated, and 

 the median longitudinal impunctate line reaches from apex to base, 

 but is very inconspicuous and sometimes hardly visible ; the elytra 

 and under side are as in G. ignitus. 



Length 8^-11 mm. ; width 5i-7 mm. 



This species has a very wide range in South Africa ; the sculpture 

 of the prothorax is very variable and at times approximates that of 

 G. bicolor, but in some examples from Natal it is almost impunctate.

 base, ligula bi-lobate, sub-styliform, sub-membranaceous and cihate ;

 incurved, a little narrower at base than the basal part of the first 

 one, third one thin, subulate ; maxillae very robust, apical inner part 

 produced in a distinct hook, upper lobe very short, briefly fasciculate,
