E. velleripennis Grt. (6 h) is a very dark, blackish-brown species with indistinct transverse lines 
which are often only traceable by dots on the veins; both the upper maculae large, surrounded with black, the 
reniform macula often with a grey spot distally; undulate line indicated by a row of black and grey dots on 
the veins. Hindwing white, on the veins and margin brownish, in the $ entirely darkened. Canada, United 
States. 
E. acornis Sm. = megastigma Sm.) (6 h). Yellowish brownish-grey, strewn with black with 
indistinct markings; maculae light, large, encircled with brownish, between them more or less darkened, parti¬ 
cularly in the $; the posterior transverse line is indistinctly double or reduced to dots. Hindwing white with 
a faded dark marginal band. British Columbia. — f. testula Sm. (6i) is more grey with entirely faded, nebulous 
markings; there is also a median shade darkening the space between the maculae. 
E. taura Sm. is greyish-brown with distinct markings; transverse lines double, the posterior one 
only partly double; the irregular undulate line marked by small black triangular spots; a blurred median shade 
darkens the cell between the maculae which are encircled with black; reniform macula somewhat lighter than 
the ground. Hindwing yellowish with a broad, dark marginal band. Expanse of wings: 36 mm. Assiniboia. 
E. alko Streck. (= sessile Sm., termessa Sm., naevula Sm.) (6 i) is allied to the preceding; ground¬ 
colour variable, reddish or yellowish brownish-grey, the markings more or less blurred, the transverse lines double, 
the maculae rather large, encircled with black, the ring-macula elliptical or almost round, the cell between them 
darkened, the reniform macula crossing the cell below; the undulate line is very indistinct, at the costal margin 
marked by a dark triangular spot before it. Hindwing yellowish white, towards the margin darker. Colorado, 
California. 
E. choris Harv. (— cogitans Sm., achor Streclc.) (6 i) is lighter yellowish-brown, dusted with grey, with a 
faint black basal ray, the transverse lines indistinctly double, the posterior line only traceable by double dots 
on the veins. Ring-macula oblong elliptical, finely encircled with black, the reniform macula only proximallv 
bordered with black. Hindwing white, at the margin brownish. Nevada, Colorado. 
E. nostra Sm. (6 k). Reddish-brown, strewn with black, with a grey costal-marginal streak; maculae 
surrounded with black, pupilled dark, the cell before them and between them black, the posterior transverse line 
double; the undulate line proximally bordered by black sagittae, behind it the marginal area is darkened. Hind- 
wing greyish-brown. California. 
E. piuralis Grt. (6 k). Forewing at the costal, distal and proximal margins grey, in the disc ochreous 
with reddish-brown stripes in the spaces between the veins; transverse lines absent except the whitish undulate 
line being dentate below the centre; the median and its branches are striped grey and black, those from the 
lower cell-angle being white; both the upper maculae are encircled with whitish, grey, the ring-macula oblong, 
pointed, the reniform macula strangulated, below produced towards the base. Hindwing white, towards the 
margin brownish. Nevada, Colorado. 
E. biformata Sm. resembles mimallonis (6 i) by the same ferruginous, somewhat smoky ground¬ 
colouring; the markings therein are almost entirely extinct, only at the costal margin better visible, in the 
^ more distinct; transverse lines double, the posterior distal line only marked by dots on the veins; median 
shade indistinctly present; maculae hardly visible by yellowish scanty strewing; undulate line only marked 
by the darker marginal area. Hindwing brownish-grey. California. 
E. serricornis Sm. Reddish ochreous, strewn with a darker colour. Transverse lines double, the posterior 
line only marked by dots on the veins; ring-macula faded, with a light ring like the darker reniform macula; 
undulate line light, proximally shaded dark, the marginal area behind it greyish-brown. Hindwing whitish, 
towards the margin brownish. South California. — f. if odes Sm. (= epictata Sm.) (6 k) has a median shade 
darkening the space between the maculae in the cell, the posterior transverse line is present and dentate. 
Arizona. — f. tocoyae Sm. (6 k) is dusted brick-reddish on the yellowish ground, the transverse lines are filled 
iip with yellowish, the maculae encircled with the same colour. California. 
E. tetrica Sm. Yellowish-reddish, dusted with grey, similarly marked as the preceding, but the maculae 
larger, surrounded with blackish, the median shade being absent; the lighter undulate line is very indistinct. 
Hindwing brownish-grey, towards the base lighter. Expanse of wings: 35 to 37 mm. Texas, Nevada. 
E. medialis Sm. {— kerrvillei Sm.) (7 a) is light yellowish-grey, dusted with brownish, the transverse 
lines indistinctly double, the posterior line dentate; maculae large, lighter than the ground, strewn with dark 
in the centre, with a distinct median line between them; undulate line traceable by small dark spots. Hind¬ 
wing white with a darker margin and discal spot, in the $ brownish-grey. From Texas. — f. truva Sm. is more 
reddish-grey, strewn with black, with interrupted transverse lines, the marginal area more intensely strewn 
with blackish; the median shade is much more distinct. Colorado. — f. poncha Sm. is very light yellowish- 
white without any reddish or flesh-coloured tints, and in the $ the liindwings are also white like in the $; the 
median shade is narrower and extends from the lower cell-angle close at the postmedian and parallel to it; 
likewise from Colorado.
