LETHE.

basal joint half the length of the tarsus, with but a few very short spines on the underside. 
Ungues very much curved. Paronychia very slender. 
" Abdomen small. 
" The hairy eyes, slender elongated palpi, dilated base of the costal vein of 
the fore wings, the middle and outer discocellular veins of nearly equal length, 
and the acute termination of the discoidal cell of the hind wings by the 
junction of the outer discocellular vein with the median vein at the origin of 
its third branch, are the chief characters of this genus." {Westwood, I. c.)

" Alis denticulatis, cinereo-fuscis, subtus pallide-flavescentibus ; antieis maculis duabus flavidis, 
atque oceUo unico interposito, in fem. fascia maculari flavida ; posticis sex oeellatis, ocellis 
omnibus nigris, albo-pupillatis, flavo-cinctis ; illis subtus basi strigis angulatis fuscis, ocellis 
sub plaga albescenti positis : Imo (antico) majore, 2, 3, minimis cxtus distantibus, ultimo 
(aiiali) pupilla geminata. Enverg. 2 po.-2 po. 2 lign." (Menc'tries, 1. c.) 
Menetries (l. c.) figured both sexes of epimenides, placing the species in 
the genus Lasiommata. Staudinger considers it a Pararge. Butler formed 
the conclusion that the two sexes represent distinct species belonging to 
different genera, and renamed the female Neope fentoni, leaving the male in 
the genus Lasiommata. Elwes (P. Z. S. 1881, p. 907) places the species in 
Lethe, to which genus it seems to have close affinities. Its nearest ally is, 
liow^ever, Pararge roxelana, Cr., a species occurring commonly in several 
parts. of S.E. Europe and Asia Minor. 
Occurs in Central and Western China and mountainous districts of Central 
and Northern Japan. In the Corea (according to Fixsen) the var. epaminondas 
as well as the type is found, as also in Amurland.
