POLYHIRMA EDAX, Per., 



Trans. S. Afric. Phil. Soc, vi., p. 13. 



Black ; head with a greyish tomentum ; prothorax elongato- 

 cordate, longer by one -fourth than broad, very broadly grooved in 

 the centre, with the groove filled with a greyish white tomentum ; 

 elytra with a small scutellary grey patch ; oblong, truncated 

 diagonally behind, very depressed, each one with seven entire sharp 

 costse and a lateral one reaching from the apex to three-fourths of 

 the length ; intervals with a regular series of shallow alveolae, 

 hardly shallower at the apex than at the base. 



Not unlike P. gracilis, this species is at once distinguished by the 

 more depressed elytra and the shallowness of the alveolae of the 

 intervals, which are of equal width from base to apex ; the general 

 size is also larger. Length 23 mm. ; width 7-8 mm. 



Hab. Ovampoland.

 prothorax elongato-cordate, one-fourth longer than broad, narrowly 

 grooved in the centre, the groove filled with a white, or whitish- 

 yellow tomentum ; elytra with a sutural white or yellowish band 

 reaching from base to apex, and a lateral marginal one, oblong, 

 truncated obliquely behind, convex, but depressed at the apex, with 

 eight acute costae on each side, the outer one reaching short of the 

 base, and the intervals deeply foveate, the foveae shallower at a short 

 distance from the apex. Length 21 mm. ; width 7 mm. 



Hab. Zambezia (Victoria Falls), Ovampoland. 



In the examples from Zambezia, the sutural bands are white, and

Head with a greyish tomentum ; prothorax slender, one-third
