As common as the above-mentioned species. Both P. xitthiis and 

 machaon frequent not only fields and gardens, but also high mountains of 

 the islands such as Daimanji, Dangyö, Takasaki, Takuhi and Yüge. 



3. Papilio bianor Cram. (Karasit-ageha). 



Leech, Butt. China, 11, p. 527 (1894); Papilio maackii Men., Fryer, 

 Rhop. Nihon., p. 3, pi. 1, fig. 3. (1886). 



Common in Dögo. In Dozen I have met with the species only once 

 at Takuhiyama on Aug. 22nd. 



4. Papilio demetrius Cram. (Kitro-agcha).

Not uncommon. Mr. Sasago of the Shimane prefectural office told me 

 that he had observed the butterfly flying in Ömori-jima, a small island 

 lying midway in the strait between Dozen and Dögo.

A single male captured on Mt. Dangyö on Aug. 10th. The species 

 seems to be quite rare.
