*Papilio helenus, Linn. 



Rare ; has been taken also in Shanghai and Nagasaki. 



*Papilio pamnon, Linn. 



This gorgeous butterfly is not uncommon about May, and con- 

 tinues to visit the island from time to time until September. 



*Papilio memnon, Linn. 



This is one of the largest of the Hongkong Lepidoptera. The 

 markings of the female are totally different from those of the 

 male, which is altogether a smaller insect. Also Southern Japan. 



♦Papilio sarpedon, Linn. 



Quite common throughout the year. North China and Japan. 

 'Papilio demetrius, Cramer. 



Occasionally seen in autumn. Common in Japan. 

 *Papilio paris, Linn. 



Abundant. A beautiful insect, always to be found near Hyliscus: 

 rosa sinensis. 



Papilio clytia, Linn. (var. dissimilis, Swainson). 

 *Papilio panope, Linn. 



Papilio polytes, Linn. 

 *Papilio agenor, Linn. (var. alcanor, Cramer). 

 *Papilio bianor, Cramer. 

 *Pieris rapae, Linn, (crucivora, Butler). 



One of the commonest butterflies ; found all the year round. 

 In markings and size it is very variable. As a rule, it feeds on 

 cultivated Cruciferse. 



*Pieris napi, Linn, {megamera, Butler; melete, Men.), 

 Pieris canidia, Sparrm. 



*Tereias multiformis, H. Pryer {Hecabe, Linn.; mandarina, Del'Orza; kccabeoides, 

 Men.; sinensis, Sue J Mariesi, Butler; anemone, Felder; connexiva, Butler; 

 tesiopc, Mon. ; sari, Horsfield). 



Thanks to the scientific investigation of Mr. H. Pryer, it is 

 now demonstrated that this butterfly is found in nearly every 

 country, and that the long list of varieties do not constitute 

 special species, as most of them interbreed without difficulty. 

 It is abundant throughout China and Japan.
