Junk River, Liberia (F. X. Stampfli). 



This species is allied to /. lineola Westw. , but besides 

 dissimilarity in colour and markings , it may be distinguished 

 from that species by the absence of the elevated point at 

 the apex of the clypeus. The only specimen I have seen 

 is the female belonging to the Leyden Museum ; the type 

 of lineola in the British Museum , with which I have com- 

 pared it, is also a female. 



Polyplast^is, n. g.
