Huphina nerissa, Belenois mesentina, Cntophaga paiilina, and 

 Delias e.iicharis, all had a scent veiy suggestive of that of 

 sweet-briar. It was probably confined to the male sex. 



A smaller group of Pierines, comprising Oanoris napi, 

 G. ohracea, and G. meletp, had a strong and very character- 

 istic scent I'eminding one of lemon-verbena. It was certainly 

 confined to the male sex. 



On the other hand, Ganorh hrassicie. has a scent of its own, 

 somewhat like violet-powder. Thus three species in one 

 genus had distinct scents, but of these one was shared by 

 many widely-spread genera. He believed that when more 

 was known of these scents they might prove of considerable 

 philogenetic value. 



Several Danaids, viz. Crastia cor^, C. asela, C. amymone (at 

 Macao), Isamia midamns (at Hong Kong), Paralitica ceylonica, 

 and Chittira fumata, all had a strong odour like acet3dene. 



Limnas chrysippufi had a faint odour like cockroaches or 

 musk-rats. He was unable to say whether these Danaine 

 scents were confined to the male sex, although he believed 

 it to be the case. 



His observations on seasonal forms were to the effect that 

 the forms of Precis agreed closely with wet and dry conditions, 

 but this was not so in the case of either Catopsilia pyranthe 

 or Terias hecahe. 



He called attention to the fact that the anal lobe of certain 

 Lycpenids is set at right angles to the hind-wing ; a fact 

 usually lost in cabinet specimens by the results of setting. 

 By specially set specimens and drawings taken from the 

 living butterfly he showed that this structure, together with 

 the tails, produced the appearance of a head and antennae, 

 and was pi'obably protective. 



In conclusion he showed by the lantern, photographs of 

 some of the localities visited.
