" Wings above rufous brown ; anterior wings with four discal greyish-white spots, one largest and 
sublunate in cell, a smaller spot above it and two beneath cell divided by the second median 
nervule, obscure dark fascias ; posterior wings with discal and outer marginal dark fascise. 
Wings beneath as above, but slightly paler. Body and legs more or less concolorous with 
wings.

The female (hitherto unnoticed) is rounder in the wing than the male, and 
the spots on primaries are subdiaphanous white. 
Occurs fairly commonly in Western China at Chia-kou-ho, Wa-shan, and 
Ta-chien-lu. 
None of the Western Chinese specimens that I have seem to agree exactly 
with those from Sikkim ; they are more suffused and, as a rule, considerably 
larger. The most typical example in my Chinese series of C. dan is one 
taken by myself at Foochau in April. 
From Moupin, Wa-ssu-kow, and Pu-tsu-fong I have received a form which 
differs so considerably from the type that I describe it as : — 
Var. dea, var. nov. (Plate XXXVIII. fig. 10, c? .) Larger than the type. Primaries uniformly 
darker ; all the hyaline spots much larger, exhibiting a tendency to become confluent ; sub- 
apical spots elongate and placed obliquely ; sometimes there are one or two small spots below 
the subapical three. Under surface much brighter than in typical C. dan. The yellow 
transverse bands on secondaries much more conspicuous ; primaries also more suffused with 
yellow and the fringes more distinctly chequered with white. 
Expanse 48 millim. 
According to Elwes C. dan is common in Sikkim up to 4000 feet from 
March to October. 
Distribution. Continental India, N.W. Himalayas, Cachar, Burmah, China, 
Malay Aixhipelago. 
Coladenia vitrea, sp. nov. (Plate XLI. fig. 15, 6 .) 
Male. Blackish grey, with numerous semitransparcnt spots. Primaries have six central and 
five subapical spots, the first, third, fifth, and sixth of central series small, and the fourth and 
fifth subapical minute. Secondaries have a subbasal spot, a large almost quadrate central 
spot with a small linear one below it and a curved series of seven spots beyond it ; the anal 
fourth of these wings is greyish. Fringes of primaries of the ground-colour; of the 
secondaries white, except at outer angle, where they are of the ground-colour, spotted with
