Twenty-two specimens, of which all were captured at Medje 

 except two caught at Gamangui in February and one in June. The 

 specimens from Medje were mostly taken in June, but there are indivi- 

 duals labelled as captured there in every month from March to August 

 inclusive.

I refer to this species a single male, taken at Medje, August 24, 

 1910. It differs somewhat from the type, in that the blue-gray color 

 extends from the base of the fore wing almost entirely over the wing, 

 and is not restricted to its basal area. In other respects it agrees en- 

 tirely with the figures and descriptions given by the author of the species.

There has existed some confusion as to this species. I have in my 

 possession a long series of males and females collected for me by the late 

 Dr. A. C. Good in the valley of the Ogove River. A number of pairs 

 were taken in coitu. This series shows clearly that the insect, which was 

 in 1883 described by Mceschler imder the name spica, is the male of the 

 butterfly which Donovan in 1824 figured as the female of P. rhodope 

 Fabricius, which it is not. For the form figured by Donovan I now propose 

 the name donovani to distinguish it from other female forms of the same 

 species. Besides the females belonging to this varietal form there are 

 numerous other females, also taken iji coitu with males of M. spica, in
