Gymnopleueus wahlbeegi, Fahr., 

 Insect. Caffrar., ii., p. 183. 



Coppery green on the upper side, and very shining, legs and 

 under side shining metalHc green ; head and clypeus covered with 

 minute granules set moderately close to one another, and very 

 distinct, edge of clypeus slightly foveate ; prothorax covered .with 

 small granules set very close to one another, median part of the 

 disk with a faint, yet discernible, median line reaching from a short 

 distance from the base to about the median part, and on each side on 

 the base itself there is a very distinct linear impression ; the outer 

 margin is nearly straight from past the middle to the base, where it 

 is recurved and angular ; elytra very finely striate, with the intervals 

 plane and covered with small granules somewhat dense but not 

 touching one another ; the first and second, and also sometimes the 

 third intervals are slightly plicate at middle ; pygidium aciculate ; 

 metathorax produced in a sharp triangular process ; it has no longi- 

 tudinal line or impression, is very closely punctulate in front on 

 each side of the triangular process, and is sparingly granular 

 laterally. 



Intermediate in sculpture between G. cajfcr and G. iwofanus ; 

 from the former it is distinguished by the closely granular prothorax 

 and the presence of the two linear impressions on each side of the 

 centre of the base, and by the shape of the metasternum which 

 projects a good deal more in front and is not grooved ; it differs 

 from the latter in the more shining appearance, the sculpture of the 

 prothorax is nearly identical, but the intervals of the elytra are not 

 closely and uniformly shagreened, they are set w^ith minute, some- 

 what distant granules, and the triangular process of the meta- 

 sternum has no transverse impression nor is the metasternum itself 

 grooved. 



Length 13-17 mm. ; width 9-11 mm. 



Hah. Ovampoland (Omrromba), Southern Ehodesia (Buluw^ayo,. 

 Salisbury). 



The Ovampoland examples have a brighter coppery sheen than 

 those from Lower Ehodesia. 



Gymnopleueus consocius, n. spec. 



Size, shape, and colour of G. thalassinus, but with a different 

 sculpture except on the head and clypeus, w^iere it is similar ; the 

 prothorax instead of being granulose is finely shagreened except in 

 the anterior part and also along the outer margin ; the median 

 discoidal line is nearly similar, but it has on each side a basal linear
