The type is in the British Mnseuni, and is the si)ecies I have been 

 naming" timpida in collections, including that of the National Museum. 

 The type of I impida. also in the British Museum, is very dark, almost 

 black ; but with exactly the same marking as in nKo-ginidrns. 1 have no 

 doubt the two will prove varieties, as this kind of Nariation is not un- 

 common in Ooriyna. At all events all my liiitpida labels should be 

 changed to read )»<tniinidcn.s. as I have changed them in the National 

 Museum
