colour can be said to be white : some other cJcJ, from Warri, Niger, are also paler 

 than usual, but not white. 



In hifrncla the jiroportion between white and orange specimens is quite 

 different. We have infracta from Unyoro, Uganda, Nandi country, Eldoraa 

 Ravine, Abyssinia, Kondeland (uorth of Lake Nyassa), and Natal. Doherty did 

 not tind the species at the Kiknyu Escarjiment, nor did Dr. Ansorge meet with 

 it in Kikuyn and the eastern parts ot British East Africa ; it occurs, however, 

 in Usambara, according to Banmniui, and at the Kilimaudjaro. Of 38 cJcJ and 

 17 ? ?, no less than 21 $$ and 8 ? ? are white or nearly so — that is to say, 

 about half the number of specimens of iiifnicta belong to the white form. In 

 tiiis form which is not seasonal, occurring with the orange form dnring the 

 rainy and the dry seasons, the brown and black colours are intensified. This is 

 especially noticeable in the ? ?, the white ¥ ? resembling the $$ rather closely, 

 while in the orange ? ? the orange colour is, as a rule, much more extended than 

 iu the orange $$. 



The Abyssinian specimens are not different from the variable infracta.

The Abyssinian and Somaliland specimens agree with the West African 

 subspecies, not with the South and East African one. Angola is inhabited by 

 the latter, while in the Congo basin the West African subspecies occurs. The 

 blue and the orange-red forms occur both in the dry and wet seasons. The two 

 forms are structurally identical, while they differ considerably from their allies 

 in both sexes not only in the sexual armature but also in other organs, the last 

 segment of the mid- and hindtarsi, for instance, bearing four ventral rows of 

 spines instead of two, the ventro- lateral si)ines not being all reduced to hairs, as 

 is the case in most other Precis.

Our s]ieciraens from Angola (Rivers Bolumbo, Calweha and C'ubal) belong 

 to the South and East African subspecies P. octavia sesamus. As seaamus is the 

 first name given to specimens of the South and East African geographical variety, 

 it is the name for it, not natalensis, which is of a much later date.
