dark triangulär spots in the marginal field of the tegmina are not 

 black in the specimen before us, instead being bluish gray but 

 clearly defined and of the pecuHar form found in this species. 



The only previous records of the species accompanied by 

 localities were from the Congo, but one of these with exact data 

 and that from Madimba, and one from Ruwenzori *). Our record 

 is another Hnk in the chain of evidence extending Congo forest- 

 land types into the Uganda region.

The ränge of this fine species is now known to extend from 

 Liberia (Rehn) to Gaboon (Westwood), and it seems probable 

 that there is a reduction in number and an increase in width of 

 the dark transverse bars of the wings southward. Our material 

 is not sufficient to establish this as a certainty, but the figures 

 given by Westwood**) of Gaboon specimens, which represent the 

 most extreme southern locahty from which the form is known, 

 shore the transverse bars to be fewer in number and individually 

 broader than in Liberian specimens of both sexes. The Cameroon 

 specimens are essentially the same as the Gaboon specimens in 

 this respect. The measurements of the present material are as
