RHOPALOCERA N I HON I C A. 



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 tlie 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.

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

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

 high mountains.

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.
