The Tsetse-fly Glossina caliginea, Austen, rejected by 

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

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

 G. caliginea, Aust. The specimen had been bitten and I'e- 

 jected by a monkey under the circumstances described by Mr. 

 W. A. Lamborn in the following paragraph written from Oni, 

 March 24, 1912:— 



"Good breezes are now blowing, aud so 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 

 settled 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 Mona picked 

 it up, smelt 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, and 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 Marshall had suggested to Prof. Poulton that the 

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

 the monkey. 



Families 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 diffei*eut biological problems : — 



1. Salamis cacta, F. — The Qriental Kallimas were well known 

 to exhibit the most remarkable valuation in the colours and 

 patterns of the under surface. It was generally believed that 

 these individual differences, which appeared in the broods of 

 both wet and dry seasons, would be found in the butterilies 

 raised from the eggs laid by a single female, but so far as 

 Prof. Poulton was aware this conclusion had never been 

 tested by breeding. It was therefore very satisfactory that 

 Mr. Lamborn had succeeded in rearing from a batch of small 

 larvae found upon the upper surface of a single leaf, a family 

 of S. cacta, allied to Kallima and showing the same kind of 

 individual variation. The larvae were found in the forest
