EREBIA. 
‘241 
The great general similarity between the species of this genus 
would cause anything like lengthy descriptions to involve con- 
siderable repetition ; in describing the Erehice, therefore, we have 
principally to notice the expanse of the wings, their colour, the 
colour and extent of the submarginal bands, and the size and 
number of the spots, and whether they are ocellated or not. The 
females are usually larger than the males, and with light and more 
distinct markings beneath. The life-history of all but a few 
species is entirely unknown ; this is perhaps accounted for by the 
fact that so few entomologists who visit the places where the 
imagines abound are able to stay long enough to watch the earlier 
stages ; to this may he added the extreme difficulty or impossibility 
of obtaining proper food-plants for the larvae in localities far distant 
from their real habitat. There is a wide field of work in alpine 
regions open to those who wish to bear their share in taking away 
from entomological literature the reproach of having to write 
“ Larva unknown ” against the majority of the species of 
Erehia. 
1.— E. Epiphron, Kutz. Btr. hi. 131, G, 7 (1783); 0. i. 1, 258; 
H. S. 92, 94 ; Fit. 544, 1, 2. 
Expands from 1-25 to 1-50 in. Marginal fringes dark brown. 
Wings brown, darkest at the base ; submarginal band marked with 
about equal intensity on all the wings, narrow, and generally 
broken up into four or five spots on each wing, fulvous in colour, 
each fulvous patch containing a distinct black spot, which some- 
times has a white centre. Under side similar to the above, but 
paler, both in the ground colour and the fulvous bands. 
Times of Appeaeance. — June and July. 
Habitat. — Elevated meadows and mountain-slopes in Ger- 
many, Silesia, and the nort-east of France (the Vosges and Ehine 
Provinces). It is less widely distributed than the variety Cassiope, 
described below. 
Laeva (of Cassiope). — Pale green, with longitudinal lines of a 
darker colour ; a lateral stripe of a white colour runs along the line 
of the spiracles. Feeds on various grasses, principally on Boa 
annua. PI. LVIII., 1.
