the male with a strong lemon-verbena scent; and Colias poliographus, 
Motsch. (the Far-Eastern form of hyale , auct.). This last, the Japanese 
Pale Clouded Yellow, occurred on each day of the expedition, hut 
between Megawa and Shimono-suwa, at from 2000 to 3000 ft., was 
quite abundant—indeed I even succeeded in netting a specimen from 
my jinrikisha! Papilio machaon (several of the specimens very 
pale) and P. xuthulus were both common throughout, the latter 
extending up to our highest point, 5500 ft., above the summit of 
the Wada-toge. 
I only brought away two moths from this expedition, both 
Geometers. Abraxas miranda occurred at about 2000 ft., while 
Panagra petraria , Hubn., was found in a wood at about 3500 ft. 
The Caddis-fly Stenopsyche griseipennis, McLachl., came to light 
at Oya, cirea 2000 ft., on May 10th. The next morning I took at 
the same place Chrysophanus turcicus. 
At Karuizawa, 3300 ft., on May 11th, I met with Pyrameis 
indica, Herbst, as well as the large Notodonta-\i\iQ Geometer, 
Pachyligia dolosa, Butl., while the small black Arctiid Diacrisia 
caesarea , Goeze ( Chelonia luctifera , Esp.), came to light. 
On May 12th we ascended Asama-Yama, 8280 ft., the highest of 
the active volcanoes of Japan. The ascent is quite easy, being for 
the most part over small scoria, but we were unfortunate in our 
weather. The strong smell of sulphur declared our proximity to the 
crater, but the cloud was so dense that we literally could not see 
more than five yards; moreover, the wind was so strong that it drove 
the rain horizontally, while every now and then a stronger gust than 
usual sent us staggering. Any idea of a view was out of the 
question, and common prudence suggested that our position was not 
without danger, so we had to beat a rapid retreat. The next morning 
it was tantalizing to see from the train the summit of Asama-Yama 
far above the clouds, with a wreath of steam slowly rising from the 
crater—the very ideal of peaceful repose.

Quite apart from the wonderful temples, the great Cryptomeria 
avenue, and the curio-shops, FTikko left a most vivid entomological 
impression on my mind. 
Together with the now familiar Blanaida goschkevitschii was the 
wet-season form of the comparatively insignificant Yphthima zodia. 
In a wood at the foot of Toyama, at an altitude of some 2100 ft., the
