For the distinctions o£ this race see Neumann's original 

 description. There are no specimens available from the 

 type-locality, except one at Tring, und the locality of that 

 is doubtful; it does not appear to differ from the last race. 



Specimens. None examined. 



Note. — There are in the British Museum two specimens 

 from the Manenguba Mts., Cameroon, which are more 

 sparsely marked below than in F. h. thornei. Material from 

 more localities in Cameroon would be of interest."
