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

 needed as it will in llie 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 larvae with every 

 possible tree, but could never induce them to feed. 



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



Locality ― Yokoliama. 



Food-plant ― し e"is sinensis. Pet s. 



Time of appearance ― June, August, October. 



丁 1" insect a[)pears 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 bu rrows of Cossus 

 and otlier destructive internal feeding Lcpidoptera and ColeopLera whicli so commonlv attack Uie oak, 

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

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

 the usual A pa tit ra tapering cylindrical shape, witli strongly bifurcated head. 



65. Limenitis populi, Linn. (PI- 5， fig- 7-) 



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

 since from any oilier locality. 



66. Limenitis sibylla, Linn. (Pi, 5、 fi g' 15') 



Localities ― Yokohama s Fuji-san, N ikUo. 

 Food-plant ― Lonicera japonica, Tlum. 

 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- m-) 



Local i lies ― Yaniato, Satsmna. 

 Time of appearance ― August. 



In the year 1876, while descending the mountain Omine-san -jo, towards Kasliiwagi, 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 Kaeoshima, but unfortunately did not 

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