in studying the cocoons of Porthesia similis, Fuessly. Although 

 he had been careful to touch the cocoons only with the tips 

 of the forceps he well remembered the irritation which had 

 been caused, especially on the neck beneath the collar.

"A very large company of these larvae was pointed 

 out to me by the native clerk, on the trunk of a tree 

 in the village 1£ miles away [from Oni] on October 18. I 

 had the tree felled and collected them and they formed 

 cocoons between October 20 and 24. The hairs on the 

 larvae are intensely urticating, and, as they come off readily, 

 float in the air if there is any draught. They get into one's 

 eyes and produce a troublesome conjunctivitis. The cocoons 

 are massed together side by side and are covered with the 

 downy hairs from the caterpillars so that an even surface is 

 produced, and the hair comes off them very easily too. As 

 I kept feeling skin irritation as a result of hairs blowing 

 about, I placed the boxes outside, and the female Mona must 

 have gone to investigate the cocoons, for I found one torn 

 open and lying on the ground, the pupa being there but 

 damaged. The monkey suffered very badly for her curiosity, 

 for her eyes became so swollen and inflamed that she could 

 hardly see out of them, and the hairs were so urticating to 

 her skin that she rolled on the ground trying to scratch 

 herself with all four feet at the same time, and it was some 

 days before she was herself again. I still left the boxes 

 outside but none of the other monkeys went near them. Nov. 

 17, 1911." 



The anal tufts of the female Glutophrissa protruded 

 during courtship. — Prof. Poulton drew attention to the 

 following observation recently made by Mr. Lamborn at 

 Oni:— 



" On December 27 I saw a male Glutophrissa saba courting 

 a female. She was resting on a leaf with wings expanded. 

 Her abdomen was raised to an angle of rather more than 

 45° to the thorax and two little tufts very similar to those pos- 

 sessed by male Danainae protruded from the anal extremity. 

 The male fluttered round her very closely, occasionally
