Very common in Dögo. In Dozen I have not seen a single example 

 of this butterfly. This is remarkable in view of the fact that the two 

 islands are separated only by a strip of sea not more than 6 miles across. 

 As this butterfly is rather rare in Hondo, I may here give some observa- 

 tions on its habit made during my stay in Dögo and also in Prov. Kii. It 

 is just the same in the two localities. 



The butterfly is found commonly in places near the sea-shore, but 

 never in the interior of the island. It flies early in the morning or late in 

 the evening in fine weather. In the middle of day it does not fly in the 

 air, but rests in some cool shady place along a stream or in a forest. At 

 rest the wings are held not vertically but horizontally, covering the front 

 third of the secondaries with the primaries, so that the yellowish-white 

 spot of the former is concealed by the latter. The butterfly is not easily 

 started unless threatened by danger It spends the greater part of the day 

 in repose. In its flight to and from the resting place, apparently much the 

 same route is taken every time. In Prov. Kii, Mr. Asahina discovered 

 on the side of a mountain a spot which the butterfly regularly passed 

 during its flight up and down the mountain at a certain hour of the day. 

 Advantage was repeatedly taken of the discovery for the purpose ot 

 obtaining specimens and that with success.

Common in Dogo, but very rare in Dozen. In the latter island I 

 have seen only a single specimen on Takasakiyama, on Aug. 22nd. The 

 species much resembles the foregoing in general appearance.
