PBAOGENA NATALENSIS. 



Colour, shape, and size of P. affinis ; the difference consists in the 

 absence of a median longitudinal impressed line on the prothorax, 

 the punctures of which are also deep but somewhat less closely set 

 in the discoidal anterior part ; the elytra have also the bluish tinge 

 on the median dorsal costse, but the latter are more plane and more 

 distinctly punctulate especially in the female. 



Length 15 mm. ; width 6 mm.

PRAOGENA CAPICOLA, n. sp. 



Chestnut-brown, with the prothorax fuscous and the elytra dark 

 chestnut with a metallic tinge turning to purplish with a faint 

 greenish dorsal band ; head irregularly punctate ; prothorax small, 

 rounded laterally in the anterior part and plainly sinuate above the 

 base, covered with closely set, round punctures, leaving a plain, 

 smooth, narrow longitudinal median line, slightly more obliterated 

 in the anterior than in the posterior part ; elytra punctato-striate 

 with the intervals costate, tectiform, and punctulate. 



Length 12-14| mm. ; width 4-5| mm.

PRAOGTENA BECHUANA, n. sp. 



Black, with the elytra alternately banded transversely with some- 

 what dull purple and green ; the head is closely and irregularly 

 punctulate, the prothorax is sub-parallel laterally, but slightly sinuate 

 above the basal angle, very closely punctate with the punctures deep 

 and having in the centre an impressed line very plain in the posterior 

 part, and obliterated in the anterior; the cost* of the elytra are 

 sharply tectiform and plainly punctate, and the purplish transverse 

 bands are narrower than the green ones on the dorsal part, but 

 broaden considerably towards the outer margin. 



I have seen one example only of this easily recognisable species . 



Length 12 mm. ; width 4 mm.
