HESTINA. — EUEIPUS. 
147 
This form occurs at Moupin and Wa-shan, Western China, in June and 
July, and at a locality three days north of Ichang, Central China, in August. 
I met with the typical form in Central Japan in July. It is also recorded 
from Yesso and North Japan by Mr. Pryer, who adds : — " This insect appears 
twice in the year, and may often be seen flying around trees, especially Celtis 
on which it feeds. Like E. charonda, it is very fond of frequenting the 
mouths of the burrows of Cossus and other destructive internal-feeding Lepi- 
doptera and Coleoptera which so commonly attack the oak, chestnut, and 
willow trees in this country. 
" The larva hybernates on the bark of the twigs of the tree, and is then grey, 
but as soon as the leaves appear in the spring it changes its skin and becomes 
green. It is of the usual Aimtura, tapering, cylindrical shape, with strongly 
bifurcated head." 
Hestina oberthiiri. (Plate XX. fig. 7, e .) 
Hestina oberih'uri, Leech, Entomologist, xxiii. p, 32 (1890); Grose Smith & Kirby, 
Rhopal. Exot. pt. xvii. {Hestina) p. 3, pi. i. figs. 5, 6 (1891). 
Male. Greyish white, venation hroadly fuliginous ; outer margins with hroad fuliginous borders, 
that of primaries intersected by one, and of secondaries by two transverse rows of small spots 
of ground-colour. Under surface similar to above, but there is a bluish-black line on all the 
wings parallel with outer margin. Fringes white, chequered with black. 
Female differs only from the male in the rounder contour of the wings. 
In some male specimens the pale ground-colour is much suffused with fuliginous. 
Expanse 76 millim. 
This species bears a superficial resemblance to Limenitis cottini, Oberthiir. 
Occurs at Wa-shan and Moupin in Western China and at Chang-yang and 
Ichang in Central China. The female seems to be exceedingly rare, as I 
have only received one example of this sex among a large number of male 
specimens. 
Genus EUEIPUS. 
Euripus, "Westwood, Gen. Diurn. Lep. ii. p. 293 (1850) ; de Niceville, Butt. lud. ii. 
p. 15 (1886).

hind margin. 
Head moderate-sized, hairy, scarcely tufted in front.
