member of the same group, a species of L/ymmnias, almost 
certainly a form of #. phegea, Fabr. He had formed the 
group in the course of an investigation into the bionomics of 
a very fine set of butterflies from the north-eastern shores of 
Lake Victoria Nyanza, presented to the Hope Department by 
Mr. C. A. Wiggins. Still later Mr. Wiggins had captured 
and presented further consignments, including a small but 
very interesting set of specimens from Entebbe. Among the 
later series, and especially that from Entebbe, Mr. Neave had 
found additional members of the same group :—another 
Acrvine butterfly, viz. A. awrivillii, Staud., synaposematic 
with the principal model, Planema poggei; the Pseudacrea, 
exhibited by -Mr. Trimen, P. kiinowiti, Dewitz, var.; and a 
second probably undescribed species. All the above are 
obvious and strongly characterized members of the “ Planema 
pogget group”: a more outlying, but apparently distinct 
member was found in the female of Precis rawana, Grose- 
Smith.

The PrEsIDENT, who also exhibited some forms of W/. awrinia 
taken by Mr. A. H. Hamm at Basingstoke and elsewhere, 
and specimens of J. athalia, M. didyma, and M. phebe from 
Asia Minor and Persia, continued the discussion, in which 
My. M. Jacosy and other Fellows joined. 
The PRESIDENT inquired of any Fellow present whether it 
was the case that the dead leaves upon the ground in tropical 
countries tended to warp and curl in the dry season, but lay 
flat in the wet. He suggested that the remarkable tendency 
in the dry phases of many species of butterflies, with dead- 
leaf-like under-sides, to develop an elongated and hooked 
or bent apex to the fore-wing, and a greatly produced anal 
angle to the hind-wing, might thus receive its interpretation. 
The development certainly could not be explained by aftinity, 
occurring as it did in the Nymphaline genera Kallima and 
Precis, the Satyrine genus JMelanitis, and as Dr. Dixey has 
recently shown in the Pierine genus Pyrisitia. 
The Presipznt further stated that Mr. H. C. Robinson had
