which the marginal borders more nearly resemble those of M. poppea 

 (Cramer). In these, however, the fore wings are either white or very 

 faintly laved with yellow. The females of this species are therefore 

 polymorphic. 



In the Lang-Chapin Collection there is only one female which be- 

 longs to the form M. donovani Holland. It was taken at Niangara in 

 November. There are twenty-seven males of typical spica, one captured 

 at Kwamouth in July 1909, another at Avakubi in October 1909, a couple 

 at Gamangui in June, and the rest at Medje in June, July, and August 

 1910.

Six males and two females, all taken at Medje, except one male 

 caught at Munie Katoto in September. The specimens from Medje 

 were taken from June 20 to August 24, 1910.

Six males and two females taken at Medje in June, July, and August. 

 Thiss pecies is not very far removed from M. bernice (Hewitson), from 

 which it differs in having the marginal border and spots of both wings 

 smaller, and the female not suffused so broadly with fuscous upon the 

 lighter areas of the fore and hind wings. I have a long series of M. 

 bernice from the Ogove, from which this form differs in the respects 

 noted, but I am not convinced that they are specifically distinct.
