was but slight ; it appeared to be alike in both sexes. From time to 

 time I have attempted to describe this scent by such words as " some- 

 what unpleasant," " disagreeable," " ? like rue," " peculiar," " musty," 

 or " somewhat like musty straw, but less disagreeable." 



When examining the specimens at Oxford in July, 1913, five 

 months after capture, and again in October, eight months after capture, 

 the scent was still very distinct, even in the presence of naphthalin. 

 Mr. Bagnall thought it " musky," Mr. Hamm " musty," Dr. Carpenter 

 thought it " like smell of pepper, but mild pepper," while Dr. Dixey 

 suggested " the smell of the pepper-tree." The last comparison 

 struck me as apt. 



T. rumina has a striking pattern, similar on both upper and 

 undersides, it is slow in its movements and bold in its behaviour ; further 

 it is hard to kill ; when it is added that both sexes have a peculiar scent, it 

 will be seen that it has all the characteristics of a protected species. 



*Papilio cymochles, Dbl. (Trinidad, 1913). A J had a somewhat 

 unpleasant odour, described as " stuffy " ; a $ a scent described as 

 " like that of an old pipe." 



*Papilio machaon, L. (Spain, 1913). Two J $ had a strong dis- 

 agreeable odour of musty straw. 



*Papilio podalirius, L. (Spain, 1913). A ? had a decided odour 

 like straw, but not disagreeable. 



Yet once more I appeal to field naturalists to join in the investi- 

 gations of these interesting perfumes, which hitherto have attracted 

 the attention of so few.

"We are glad to be able to record the occurrence of the following 

 macropterous forms, hitherto unknown, and also a genus and species 

 which is an addition to the British List of Hemiptera-Homoptera : —
