Promecolaiifjun'a was proposed as a genus by Fowler tor 

 Lanf/iin'a dinddiata (Gudriii, Icon. R. A., Ins. ji. 314), ami is 

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



'i'here 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 jjrosternal process rather long, truncate, and 

 margined with a thickened edge, give these insects a very 

 distinct a])pearance among the Languriidcs. I suspect that 

 Longuria lyctoides. Fowler (Comptes rendus Soc. Ent. B.dg.), 

 belongs to the genus. 



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

 1 have received from the Ca|)e Colony, but has the thorax 

 quite difhrently shaj)e<l from the Langurias I have seen troui 

 that Culuiiy. The underside is not so coarsely punctured as 

 that of L. dimidiatu ; the abdomen is quite finely j)unclured. 

 Two specimens.

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 jiuncturing is tine and like that of 

 P. MarshalU. 'i he head is either black with a metallic
