PRAOGENA DITISSIMA, n. sp. 



Black, with a metallic tinge, shining, elytra having on each side 

 two coppery bands, the first of which extends on the second and 

 third costae and the other on the eighth and ninth, and also on the 

 outer margin ; head very closely punctate ; prothorax nearly parallel, 

 but slightly attenuate laterally towards the anterior angles, covered 

 with very closely set, somewhat deep, round punctures, and having 

 in the centre of the posterior part an elongated, narrow, smooth 

 space somewhat obsolete ; elytra striate, striae deeply and very 

 closely punctate, intervals narrow, sharply costate from base to apex, 

 and with the punctures of the striae slightly impinging on the sides 

 of the costae. 



Allied to -P. splendens, Makl., but narrower, the coppery bands on 

 the elytra are differently disposed ; the elytra are narrower ; the 

 prothorax is also narrower and more parallel, and closely punctate 

 instead of being nearly smooth. 



Length 14-15^ mm. ; width 4^-5 mm.

PRAOCJEXA AFFINIS, n. sp. 



Black, with the elytra purplish and the outer margin greenish, 

 oftener than not they have a slight bluish tinge on the third to sixth 

 intervals ; head covered with deep, round punctures separated by an 

 interval about equal in width to their diameter ; prothorax as broad 

 as long, plainly attenuate laterally in the anterior part and slightly 

 sinuate in the posterior, covered with very closely set, deep 

 punctures separated by a very narrow and very slightly raised 

 interval, and having a median longitudinal impressed line quite plain 

 in the posterior part but obliterated in the anterior ; elytra deeply 

 and narrowly striate, the strito finely, yet deeply punctate, and the 

 intervals narrow, tectiform on the disk and sides, and very faintly 

 punctulate. 



Allied to P. /estiva, and nearly similar in shape and colour, but the 

 prothorax is more attenuate laterally towards the apex, much more 

 deeply and roughly punctured, and the intervals of the elytra are 

 more sharply costate. 



Length 14-15 mm. ; width 5-5^ mm.
