accordance with those of Fritz M uller, who found the scent of the <$ , 

 though very delicious, rather faint and often hardly distinguishable. 

 Two $ ? were examined but no scent found. (Compare op. cit., p. 511) . 



Belenois gidica, Grodt. (Sudan, 1912). Of 13 £ $ all appeared to 

 be scentless, but in 1 $ out of 5 a faint scent was detected. 



Belenois mesentina, Cr. (Sudan, 1912). I found the £ to have a 



slight scent, variously suggesting the adjectives " musky," " aromatic," 

 " flowery." Previous results were thus confirmed. 



Pieris (Perrhybris) calydonia, Bsd. (Venezuela, 1913). 11 speci- 

 mens, all £ , were examined ; in 4 of these there was a distinct scent, 

 described as " flowery " or " like Freesia " ; in two a somewhat 

 unpleasant scent, suggesting pomade, was found. On the whole pre- 

 vious results were confirmed. 



*Pieris (Perrhybris) sevata, Feld. (Venezuela, 1913). 2 $ £ had 

 a slight but distinct flowery sceut ; 2 <j? ? were scentless. 



*Pieris (Perrhybris) phiIeta,F. (W. Indies and Venezuela, 1913). 

 Out of 10 <$ $ examined, only four yielded a scent, twice doubtfully 

 described as " peculiar," once as " heavy, somewhat unpleasant," once 

 as " strongly fetid." Of two $ $ one had a " slight fetid odour." In 

 1907 I failed to detect any odour in this species. 



*Syrichloe glauconome, Klug (Sudan, 1912). 3 tf £ out of 8 

 yielded a distinct sweet scent like that of Freesia. 



*8ynchloi : daplidice, L. (Spain, 1913). Of 32 £ $ examined, 24 

 had a scent. This was in no case strong, but variously estimated as 

 " very slight," " slight," " distinct," or " decided " ; it was variously 

 described as " aromatic," " like sweet-briar," or " scarcely pleasant," 

 but more often as " sweet," and in a majority of specimens was 

 compared to that of Freesia. Of one of the 24 $ £ the note says that 

 observation in the field showed " a slight sweet scent," but that at 

 home the butterfly was found alive in its envelope, and emitted " a 

 strong scent, somewhat like that of P. rajiM." One observation gave 

 a doubtful, seven gave negative results. In 8 out of 10 ? ? examined, 

 no scent was detected; in one "a very slight but very sweet scent" 

 was noted ; of another it is recorded " a very slight Freesia scent : no 

 doubt about it." 



Papilionin^e. 

 *Thais rttmina, L. (Spain, 1913). In 10 out of 11 <$ $ , and in all 

 the 7 ? $ examined, a scent was easily detected, though sometimes it
