" The scent of Belenois zochalia, Boisd., 3 , is not as a rule 

 very powerful. It seems to me to be of the sweetbriar order, 

 including the scent of the flower as well as of the foliage. It 

 was more distinct in a worn specimen than in two fresh ones 

 examined on the same day. Dr. Longstaff found a ' faint 

 flowery scent like that of G. brassicx ' in the single individual 

 he tested. 



" Pinacopteryx charina, Boisd., $ , has a perfume like a whiff 

 of mignonette, seldom strong and often absent. Of nine males 

 tested at different times by Dr. Longstaff, only one had a 

 decided odour, which he records simply as ' flowery.' 



"In Pinacopteryx ])igea, Boisd., <$ , the scent is distinct, in 

 some cases strong. It appears to me to resemble honeysuckle 

 — a comparison in which Dr. Longstaff concurs. One of my 

 specimens had an odour more suggestive of Philadelphia, and 

 the scent of one of Dr. Longstaff 's was noted by him as ' sweet 

 and spicy.' The female was found by me to be odourless. 



"The scent of Mylothris agathina, Cram., $ , though varying 

 somewhat in intensity in different individuals, is generally one 

 of the strongest and most distinct in the whole range of 

 Pierine odours so far as I am acquainted with them. To both 

 Dr. Longstaff and myself it appears to be exactly that of 

 sweetbriar. It is a pleasant and refreshing perfume, and is 

 easily perceptible even when the butterfly is held in the hand 

 unrubbed. The female was always found by me to be scent- 

 less ; but one tested, after death, by Dr. Longstaff, had a 

 strong ' mousy ' odour, like henbane ; an observation which I 

 can confirm. 



"The scent of Mylothris rilppellii, c?,is in the opinion of 

 both of us indistinguishable from that of M. ayathina, 3 • A 

 female specimen, when dead, was noted by Dr. Longstaff as 

 having a slight ' black-beetle ' odour ; this, however, I failed 

 to detect. 



" In nearly all the specimens of Mylothris trimenia, Butl., <$ , 

 which I was able to test, there was a strong, pleasant, 

 characteristic odour, not easily described, and quite distinct 

 from that of M. agathina. It contains a predominating 

 sweet flowery constituent, perhaps a little like that of Pina- 

 copteryx pigea, but reminding me rather of sweet-pea than of
