RHOPALOCERA NIHONICA. 23 



its wings until its imperial claims are acknowledged. If capture be missed the first time patience is 

 needed as it will in tlie course of an hour or so surely return. It has a very large flat pupa, of a beautiful 

 light green color. I have had many broods of eggs, and have tried the newly hatched larvas with every 

 possible tree, but could never induce them to feed. 



64- Euripus japonica, Feld. (Pi- 5. f ' 8 -) 



Locality Yokohama. 



Food-plant Cellis sinensis, Pers. 



Time of appearance June, August, October. 



This insect appears twice in the year, and may often be seen flying round trees, especially Celtis, on 

 which it feeds. Like E. charonda, it is very fond of frequenting the mouths of the burrows of Cossus 

 and other destructive internal feeding Lepidoptera and Coleoptera which so commonly attack the oak, 

 chesnut, and willow trees in this country. The larva hybernates on the bark-of the twigs of the tree, and is 

 then grey, but as soon as the leaves appear in the spring it changes its skin and becomes green. It is of 

 the usual Apatura tapering cylindrical shape, with strongly bifurcated head. 



65- Limenitis populi, Linn. (Pi. 5- fi s- 7-) 



Local it) Ytzo. 



During the year 1882 my collector took several specimens in the Island of Yezo. I have not seen it 

 since from any other locality. 



66. Limenitis sibylla, Linn. (Pi- 5. fi s- '5-) 



Localities Yokohama, Fuji-sail, Nikko. 

 Food-plant Lonicera japonica, Tluiii. 

 Time of appearance June, August. 



This species varies considerably in size and in the white markings of the upper side. 

 67- Cyrestis thyodamas, Boisd. (PI- 5. fi g- "4-) 



Localities Yamato, Satsuma. 

 Time of appearance August. 



In the year 1876, while descending the mountain Omine-san-jo, towards Kashiwagi, I was much sur- 

 prised to see a solitary specimen of this species, which, with some difficulty, I secured. Last year my 

 collector again saw this species, with which he is well acquainted, at Kagoshima, but unfortunately did not 

 effect its capture. South of Japan, in the Ryukyu Islands, it is not uncommon.
