found only in forested, or at least well-wooded localities, 

 and usually settled on tree trunks, often high up on them, in 

 contradistinction to many other Asilidae which usually settle 

 on the ground. He thought that the great rarity of these 

 insects in collections was due partly to their actual scarcity 

 in nature, and partly to the fact that they were extremely 

 difficult to capture on account of their wariness and powerful 

 flight. 



He also exhibited a remarkable new Nymphaline Butter- 

 fly, probably belonging to the genus Pseudacraea, taken on 

 Mt. Mlanje, Nyasaland. He pointed out that it bore a 

 marvellous superficial resemblance to Amauris lobengula ivhytei, 

 Butler, the Danaine which occurred in the same place. 



He further exhibited a number of unnamed Lycaenidae, 

 principally from Uganda. Apart from the fact that many 

 rare or unknown species were included amongst them, their 

 chief interest was that they demonstrated the marked 

 dominance of the Liptenine section of the Lycaenidae from 

 that region, and thus accentuated the resemblance of the 

 Uganda fauna to that of the Tropical West Coast of Africa. 



Mr. S. A. Neave also referred to some interesting points, 

 to which Prof. Poulton had called his attention, occurring 

 amongst the butterflies recently collected by him in Eastern 

 Uganda, particularly in the neighbourhood of Mount Elgon. 

 The specimens of Pseudacraea hobleyi from this locality were 

 remarkable for the fact that a large proportion of the females 

 were coloured like the male, i. e. with an orange band in the 

 fore wing instead of a white one, as in the typical form of the 

 female common at Entebbe. He pointed out the extreme

 interest of this when coupled with the fact that one of the 

 two Planema models, P. macarista. which has a black and 

 white female, is not known to occur east of the River Nile, 

 whereas the other, P. poggei, which has an orange band in 

 both sexes, does so. It is true that in the present case no 

 Planema of any species was actually taken during three days' 

 collecting in a patch of forest on the Siroko River to the west 

 of Mount Elgon, where the majority of the male-coloured 

 females of Pseudacraea hobleyi were taken. At the same
