RHOPALOCERA NIHONICA. 



The male is much less ornamented than the female, and is generally jet black, with a faint red patch at 

 the base of the fore wing. The female is very conspicuous, and, from the contrast of its colours, appears 

 much larger than it really is when on the wing. A tailed form is found in China, but I have not seen it in 

 Japan. Those females I have seen here are also darker than Chinese specimens. 



9- Papilio sarpedon, L. (PL i, fig- 9-) 



Localities Main Island. 



Food plant Machilus thtmbergii /.. and B. 



Time of appearance April until the end of summer. 



Very abundant. The larva feeds on the young leaves of the evergreen Machilus, their colour resem- 

 bles very closely that of -the young green leaves of this tree. 



10. Luedorfia puziloi, Ersch. (Pi- ', fig- 10-) 



Localities Yezo, Gifu. 



Time of appearance Early in April. 



This is a rare insect, and I have not yet seen a perfect specimen. It is found early in the year on 



high mountains. 



1 1. Parnassus glacialis, But. (Pi. 3, fig- 5.) 



Localities Nikko, Yezo. 



Time of appearance June, July. 



This is a mountain insect. Some specimens are suffused with smoky black, and it varies greatly in 

 markings. The female often has a horny sheath to the abdomen, but I do not think the use of this has yet 

 been discovered. 



Family PIERID/E. 



12. Aporia crataegi, L. (Pi- 3. fi g- 7-) 



Locality Yezo. 



Food plant Apple trees. 



Time of appearance Summer. 



This is abundant in Yezo, but I have not seen it south of that Island.
