fuscous, intersected by an interrupted blackisli band, the anal extremity of which is represented 
by two velvety-black spots, and a band of the ground-colour. 
Expanse 74 millim. 
Male specimens were taken at Omei-shan, AYa-ssu-kow, and Pu-tsu-fong in 
June and July at altitudes ranging from oOOO to 10,000 feet. It seems to 
be a scarce species, and the female appears to be unknown. 
Allied to L. poj)uli, var. tremuloe, Esp., but is easily separated therefrom.. 
Limenitis pratti. (Plate XVI. fig. 7.) 
Limenitis pratti, Leech, Entomologist, xxiii. p. 34 (1890). 
Black, inclining to brown towards the base of all the wings. Primaries with a white transverse 
bar, preceded and followed by obscure whitish ones, in discoidal cell ; a central series of six 
quadrate whitish spots and beyond a transverse series of smaller red spots, the upper of which 
are round, and the two nearest costa edged internally with white ; submarginal spots white, 
intersected by a line of the ground-colour, that in the second median interspace large and 
triangular. Secondaries have two black transverse bars enclosing an obscure red one near 
base ; a central series of seven white spots, follawcd by a series of smaller red ones ; outer 
margin broadly bordered with white, intersected by an interrupted transverse band. Under 
surface similar to above, but the costa is whitish and tho mai'kings are larger, those in the 
discoidal cell are well defined, and below the cell there is a large white blotch, transversely 
intersected by a blackish band ; secondaries have the costa edged with red, and there are 
some reddish and black marks on the white basal third ; the other markings same as above, 
but more band-like in character. 
Expanse 69 millim. 
One example taken in July at Chang-yang. 
This species is nearly allied to the Western-Himalayan species L. trivena, 
Moore, of which the following forms have been described : — lUjyes, Hewitson ; 
hydasjtes^ Moore ; and lepechhii, Erschoff (see de Niceville, Butt. Ind. ii. p. 161).
