GRYPTIN.E. 



Osprynchotes ruficollis sp. n. — Rufescent(perhaps disco- 

 lonred) the pro- meso- and metathorax black ; the legs of a pale 

 rufescent colour, the basai two-thirds of the hind tibiae white as 

 are also the apical half of the basai joint of the hind tarsi and the

 the costa and stigma rufo-testaceous, the nervures black. The

Length 20 mill.; terebra 6 mill. 



Katanga (Weyns). 



Vertex depressed on eitherside of the ocelli, weakly, irregularly 

 transversely striated. Mesonotum clusely, distinctly punctured, 

 except round the edges. Propleurae smooth, with a few stout stria 3 , 

 on the lower apical part. Mesopleunc strongly, irregularly striated, 

 the striœ interlacing, weaker above. Metathorax closely, regularly, 

 somewhatstronglyreticulated. Malarspace half the length oftheeyes. 



The only example appears to be discoloured, or the colours are 

 not fully developed, probably the latter, for the wings appear not 

 to hâve had time to expand fully. The species is very différent 

 from any of the known forms.
