Lethe baucis. (Plate IV. figs. 5 d , 6 $ .) 
Lethe bauds, Leech, Entomologist, xxiv., Suppl. p. 3 (1891). 
Lethe procris, Leech, 1. c. p. 2. 
Allied to Lethe hrisanda, de Niceville, but the ground-colour is not so reddish brown. Wings 
broader and rounder ; outer margin of secondaries not so produced ; oceUi smaller ; both sexes 
have a pale apical mark, and the female a white fascia resembling that of Lethe rohria, Fabr. 
Under surface : there is no pale bar in the cell of primaries ; the line commences nearer the 
centre of costa ; the ocelli of secondaries are all larger, and the central line is not indented 
below the middle. 
Expanse, 6 64 millim., $ 66 millim. 
Var. procris. (Plate IV. fig. 7, c? •) Smaller, and the outer margin of primaries straighter, 
which gives the insect the appearance of being sharper-winged. On the under surface of 
primaries the dark bars in discoidal cell are only faintly indicated. The dark transverse line 
is distinctly elbowed below costa. 
The Lethe which I have described as L. procn's does not appear, on a 
comparison with a large series, to be specifically distinct from L. baucis. I 
was at first deceived by the crushed bodies of two of the specimens, which I 
then considered to be the females, but after a more careful examination I now 
find to be males. 
Appears to be generally distributed in Western China, and also occurs at 
Chang-yang in Central China. 
Lethe rohria. (Plate IV. fig. 8, j .) 
Papilto rohria, Fabricius, Mant. Ins. ii. p. 45 (1787). 
Satyrus rohria, Godart, Enc. M^th. ix. p. 479 (1819). 
Lethe rohria, Marshall & de Nicdville, Butt. Ind. i. p. 156 (1882). 
Male. Dark brown ; primaries traversed by a broad white band from middle of costa to just above 
inner angle ; this band is interrupted by the median nervules, most decidedly by the first 
norvule ; there are three white spots near apex, but the lower one is not always well defined. 
Under surface pale chocolate-brown ; primaries have a pale violet-grey subbasal transverse 
lino and a white band as above ; there is a short white streak from costa near apex, and 
below this three ocelli, the third indistinctly formed : secondaries have six ocelli, nil with 
white pupils and yellow irides, the sixth bipupillated ; pale violet-grey subbasal, central, 
and submarginal lines, the central one angulatcd below the large costal ocellus. The ocelli 
oil flic under surface show through on Ihe upper surface, and there is sometimes a distinct 
ocellus witli white pupil in the first median interspace. 
The female is ji.ilcr in colour, and the l)and on primaries is wider.
