0. eoNNBXA. new species. 



Size and sliape of 7nargimlla ; labrum of the male yellow narrowly 

 ed^Sfed with black, that of the female very broadly infuscated at the 

 apex J elytra elongated, nearly parallel in the male, ampliated past the 

 middle in the female, deeply and broadly punctured with the punctures 

 confluent, these punctures much more narrow behind, the suture 

 ending in two long spines, longer in the male, shining bronze, with a 

 broad, dorsal green band, and a narrow white supra- marginal band 

 reaching from the shoulder to the apex ; this white line is very narrow 

 from the shoulder to about the middle, and nearly twice as broad from 

 the median to the apical part, underside and legs bluish-black. 



Length, 12-ia ; width, 3-4™""* 



Very closely allied to marginella, differs mostly by the punctuation 

 of the elytra, which is much broader and deeper, and intermediate 

 between that of marginella and lateralis, the bronze sheen of the 

 prothorax and elytra is also brighter, and the supra-marginal white 

 band is also broader in the posterior part ; from lateralis it differs in 

 the punctuation of the elytra not being so broad, and in the shape of 

 the elytra of the female, which are much less ampliated in the middle. 



Natal (Frere).
