merely a color-varietj', it occurs constantly, and I should say that it is 

 no exaggeration to affirm that at least two per cent of the specimens 

 collected belong to it.

All of the specimens in the collection belong to the varietal form 

 described bj^ Distant, which differs fi'om typical P. )nenesih€us in having 

 the transverse band of pale spots on the fore wing nearly straight, and 

 not curving inwardly near the costa in the direction of the base of the 

 wing. The typical form occurs in Sierra Leone and the northern parts 

 of the range of the insect, but the variety /orw7>r/is most prevalent from 

 southern Cameroon and the valley of the Ogove eastward into the hot 

 wooded interior of the continent and reaches as far south as Mashona- 

 land. 



There are seventy-five specimens of this insect in the collection, 

 including a couple of females. Most of them were taken at Medje, a 

 few in April, the rest from Jime to September, but chiefly in the months 

 of July and August, A small number are labelled as having been taken 

 at Niangara in November.

Twenty-three male specimens. Of these nine are labelled as having 

 been taken at Gamangui in February, six at Medje in June and July, 

 three at Bafwasende in September, four at Niangara in November, and 

 one "near Barumbu, July 31, 1909."

Plate VI, Figure 4, 9 

 P. ridleyanus is dimorphic. Two males from Medje and two from 

 Bafwasende belong to a variety in which the red color of both wings dis- 

 appears and is replaced by dull smoky gray. This is true also of a certain 

 proportion of the females of the species. I have before me as I write a 

 number of females taken by Antisdel in the Belgian Congo not far from 

 Leopoldville, some of which are colored like the typical males and are
