Karsch described the male; the female was described by Wichgraf 

 in the Deutsche Entomologische Zeitschrift, 1914, p. 345. It is some- 

 what larger than the male, paler in color throughout, with the sub- 

 apical light area of the primaries enlarged and extending along the 

 costa as a light line to a point about opposite the end of the cell. On the 

 under side it does not differ materially in its color and markings from the 

 male. 



The collection contains a set of seven males and five females, taken 

 at Medje, one male and three females in April, the rest in July and 

 August.

I refer to this species a long series of males and several females 

 the general resemblance of which on the under side of the wings to M. 

 martins and M. golo recalls the remarks of the author of the species, 

 who says that M. obscura is very like the two which have been mentioned. 

 There are, however, structural differences which clearly separate this 

 species from M. martins. One of these is the absence in M. obscura of 

 the tuft of androconia, which is always found in M. martins between 

 veins 2 and 3 near the point of their origin on the fore wing, and 

 another is the fact that the hind wing is not produced or angulated at the 

 extremity of vein 4 as is the case in M. martins. From M. golo they 

 may at once be discriminated by their more uniform!}^ dark color on 

 the under side of the secondaries. The females which I associate with 

 the males have broader wings and are paler in color than the males, 

 but, like the males, strongly recall in the pattern of the markings the 

 corresponding sex of M. martins . 



Of M. martins I have before me, as I write, an enormous series of 

 males and females taken at various localities, ranging from the valley 

 of the Ogove River to Lolodorf in Cameroon and, while superficially 

 the twg species are very much alike, so that an untrained investigator
