Promecolanguria was proposed as a genus by Fowler for 

 Languria dimidiata (Gudriii, Icon. R. A., Ins. p. 314), and is 

 also given in ray table of genera (P. Z, S. 1887, p. 361). 



There are no abdominal lines ; the eyes are not very coarse, 

 the facets being only just visible, but the depressed form and 

 the oblong and parallel-sided thorax, with finely neatly mar- 

 gined sides, the prosternal process rather long, truncate, and 

 margined with a thickened edge, give these insects a very 

 distinct appearance among the Languriides. I suspect that 

 Languria hjctoides, Fowler (Comptes rendus Soc. Ent. Belg.), 

 belongs to the genus. 



The species obtained by Mr. Marshall is very like an insect 

 1 have received from the Cape Colony, but has the thorax 

 quite differently shaped from the Langurias I have seen from 

 that Colony. 'J'he underside is not so coarsely punctured as 

 that of L. dimidiata] the abdomen is quite finely punctured. 

 Two specimens. 



Promecolanguria trogositoides^ sp. n. 



Sordide flava, capite prothoraceque, antennis pedibusque piccis ; 



iUo basi, his basi tarsisque fiavis. 

 Long, vix 6 millim.

This insect is similar in form to P. Marshalli, but is 

 smaller, the thorax is a little more contracted towards the 

 base and shows only a very faint trace of canaliculation 

 towards its base; the puncturing is fine and like that of 

 P. Marshalli. The head is either black with a metallic
