The white patch which so commonly appeared, represented 

 a patch of variable size which seemed to be always present on 

 the under surface of the hind wing of the female. This under 

 surface marking again represented the central part of the 

 bx-oad white bar crossing the middle of the male hind wing with 

 which also corresponded the white patch on the upper Burface, 

 as might be seen by holding the insect up to the light. The 

 white patch of the female appeared therefore to represent a 

 marking that u,v very ancestral in the genus Hypolimna8 

 and common to many of its species, including the remarkable 

 //. 'hxithea of Madagascar.

 'I'm: TSBTSB-FLY Glossika caliginea. A imt.n, rejected by 

 a Monkey. — Prof. Poulton exhibited the fragments of a 

 Glossina identified by Mr. K. E. Austen as a female of 

 G. caliginea, Aust. Tin- specimen had been bitten and re- 

 jected by a monkey under the circumstances described by 

 Mr. W. A. Lamborn in the following paragraph written from 

 Oni, March 'J I, 1912:— 



"Good breezes are now blowing, and bo this afternoon we 

 ran across the lagoon in the sailing boat and had tea in one 

 of the creeks. Two Glossina were rather a nuisance, and one 

 sett ltd on the leg of one of the men, who killed it with a 

 sharp slap so that it fell into the bottom of the boat. I was 

 too busy to pick it up just then, but the female filona picked 

 it up, smell it and put it in her mouth. She took it out very 

 shortly, pulled off one wing and then bit the insect in two. 

 She dropped the thorax, but put the abdomen in her mouth. 

 It was only kept there a few seconds, aud then she took it 

 out, smelt it, deposited it on the seat, and ran away. I send 

 the specimen. The Mona is very fond of Tabanidae, and had 

 caught and eaten several in the house before we went out." 



Mr. Guy Marshal] had suggested to Prof. Poulton that the 

 presence of fresh blood in the fly may have been distasteful to 

 the monkey. 



Fa.mii.iks of Butterflies bred by W. A. Lamborn in the 

 Lagos District. — Prof. Poulton exhibited the following 

 families, and referred to the strong light which was thrown 

 by them upon different biological problems : — •
