but the first two are often indistinct. The under surface is darker than in L. trimacula ; 
the apical third of primaries is limited by a conspicuous dark grey-brown transverse band, 
which runs obliquely from costa to third median nervule, and then descends in a sinuous 
course to the inner angle ; the transverse markings of secondaries are more angulated ; the 
costal double ocellus is placed rather obliquely and is more elongate in foi'm, below this there 
are five distinct ocelli ; all the ocelli, including that on the primaries, have dingy yellowish 
irides. 
Female. Similar to the male, but the apical third is limited by a broad pale fulvous band, which 
unites with the iris of apical ocellus, and is marked with whitish on the costa. 
Expanse, S 62-70 millim., $ 65-68 millim. 
This species may be at once separated from L. trimacula by the different 
arrangement of ocelli on under surface of secondaries. 
Occurs throughout Western China, at altitudes ranging from 5000-7000 
feet, during the months of July and August.

Lethe nigrifascia, Leech, Entomologist, xxiii. p. 28 (1890). 
Male. Fuscous brown, darker on the outer margins. Primaries crossed by a black band, which 
curves from the costa, and is not well defined until it reaches the third median branch, where 
it is dilated, as it also is at each succeeding vein to the inner margin. Secondaries have a 
submarginal series of six black spots set in pale rings, the first is largest, but does not greatly 
exceed the fourth, whilst the sixth is smaller and indistinct ; a pale line parallel with outer 
margin. Fringes white, fuliginous at extremities of the nervules. Under surface ochreous 
brown, fuscous towards outer margin ; abroad whitish bar crosses the discal cell; central 
transverse line whitish, ill-defined, commencing as a blotch on the costa, and bordering a 
faint reproduction of the black band of the upper surface ; a smaller white patch nearer the 
apex, and a pale line parallel with the outer margin. Secondaries have two pale violet basal 
lines, the first is indistinct after passing the median nervure, but the second continues its 
course to the submedian, where it turns in and terminates at the internal nervure ; beyond is 
another pale violet line, bordered inwardly with brown, running from costa to first median 
branch, where it turns sharply inwards and upwards for a short distance, then again turns 
and descends to the median nervure ; a fourth pale violet line traverses the wing in a wavy 
course from costa to inner margin ; this is bordered externally with various shades of brown 
and limits the outer third, which is somewhat darker than the rest of the wing, and has a 
series of six ocelli ; the first four of these ocelli are surrounded with pale violet, but in the 
last two, which are larger, this colour is only distinct on their inner edge ; the sixth ocellus 
is double ; a pale violet line parallel with outer margin forms triangular blotches opposite 
tlie last three ocelli, that at the anal angle being the largest ; fringes as above. 
Female. Colour of the male, but there is no black band on the primaries ; a blackish shade, broadest 
near the costa, where it is bordered by some pale yellowish dashes, runs obliquely to beyond 
third median branch, and then curves inwards to the inner margin ; some whitish spots 
towards apex. The under surface is pale fulvous, and the pale violet lines on the secondaries 
of the male are replaced in this sex by pale yellowish ones.
