this scent was more distinct than that of the male rhamni, but much 

 less strong than that of the male cleopatra. To me it was agreeable, 

 sweet, and suggested Freesia. 



Are we to regard rhamni and cleopatra as distinct species of 

 which the females closely resemble one another ? Or are we to look 

 upon them as but one species with a (locally) dimorphic male ? 



Dr. Dixey gave to the Entomological Society some years ago 

 an admirable summary of the facts, which was fully reported at 

 the time.t 



An obvious question arises : can the scent be directly connected, 

 or indirectly correlated with the orange scales ? Mr. Enoch's record of 

 ants attacking G. rhamni and confining their depredations to the 

 orange spots is very suggestive, especially in the light of somewhat 

 similar observations as to Danainse. 



*Aphrissa statira, Cr. A <§ had, when alive, a slight sweet scent. 



Colias edusa, auct. (Spain, 1913). b* $ $ were examined; in 

 three I was unable to detect any odour, in two a very slight chocolate-like 

 scent was suspected, in one I satisfied myself that a slight but distinct 

 scent was present, which I was disposed to compare to that of clove- 

 pink. I was, however, unable to localise the scent in the " patches."! 



Terias nise, Cr. (W. Indies, Trinidad, and Venezuela, 1913.) 

 19 $ <$ were examined of which 5 had a sweet scent, compared in several 

 instances to the peculiar smell of Convolvulus arvensis. 7 % $ gave 

 negative results. These observations confirm my experience in 1907, 

 though the positive results are proportionately fewer. 



Teracolus protomedia, Klug (Sudan, 1912)). In 6 £ g out of 241 

 detected a slight scent, not easy to describe ; the words " dusty," " stuffy," 

 " musky," " peculiar," " like wood," and " very faint Freesia " appear 

 in my note book. Previous results were thus confirmed. 



*T. eupompe, Klug (Sudan, 1912). In two $ $ out of a large 

 number examined a slight scent was observed, in one noted as " sweet," 

 in the other as " stuffy." 



T. halimede, Klug (Sudan, 1913). A £ , one of many, had a 

 distinct musky odour. 



*T. pleione, Klug (Sudan, 1913). A g , one of many, had a dis- 

 tinct musky odour.
