bordered with a somewhat lighter colour; the ring-macula is a light, the reniform macula a darker small spot, 
the latter dying away in the median shade; the undulate line is absent. Hindwing smoke-grey. Expanse of 
wings: 20 to 25 mm. From Arizona. 
E. discreta B. db McD. (21 k) is of a more slender structure and lighter than the similar mania and dubia, ducreia. 
without the white dots at the reniform macula and behind the postmedian line, and with much less dark pro¬ 
minent shading before the undulate line; the last palpal joint is shorter than in dubia, the antennae are much 
thinner and more finely ciliated; the eyes are also more scantily haired. From California, in July and September. 
E. puerilis Gr. (21 i). Forewing ochreous-yellowish, dusted with purple-red, and striped dark on the puerilis. 
veins, with grey strewing, undulate transverse lines and black dots on the veins behind the distal line; the 
ring-macula is absent or it is a minute white spot with a black streak to the reniform macula which is indistinct 
and more or less 8-shaped, with a light or white filling in the upper half, before it a broken median line; undu¬ 
late line yellowish-white, proximally bordered with brown and before it with more or less distinct black sagittae. 
Hindwing brownish-grey with yellowish fringes. United States (Washington to California). 
E. contrahens Wkr. (= theraba Morr.) (21 k) has ochreous-yellowish forewings with brownish-grey contrahens. 
strewing except the basal part of the proximal margin and an oblique apical patch; the anterior transverse line 
is double, filled up with ochreous-yellowish, the posterior line single, distally bordered with yellowish; maculae 
small, in indistinctly lighter rings and pupilled darker; the undulate line is entirely absent. Hindwing yellowish- 
brown, at the margin darker. Canada to New Mexico. 
E. rhimla Dyar (21 k). Forewing yellowish grey or yellowish-brown, shaded much darker particularly rhimla. 
in the discal and marginal areas; anterior transverse line dentate, the posterior line almost straight, only on 
the middle radial branch pointedly projecting; maculae pupilled darker, the reniform macula distally white 
behind it a light spot. Hindwing blackish with light fringes. Mexico (City) in September. 
E. conar Streck. (= quadristigma Sm.) (21 k). Forewing light reddish, dusted with purple brown, conar. 
with single, dark, on the averted sides whitish transverse stripes and black streaks on the veins behind the 
distal stripe; the macidae are pupilled black and encircled with whitish, between them an oblique median shade; 
the undulate line is only marked by the darker marginal area. Hindwing yellowish-white, on the veins and 
margin brownish. United States (Nebraska, Utah, New Mexico, Arizona). 
E. cacoeona Dyar (21 k) has dark grey forewings with a black forked basal ray; the proximal double cacoeona. 
transverse line has a lighter filling, the distal line black, distally bordered with light; instead of the coniform 
macula a black streak; the light maculae are in black rings, the reniform macula is quadrangular with a small 
black spot in the lower cell-angle, between both a black median line; the black undulate line is sharply dentate. 
Hindwing brownish-grey, towards the base lighter. Expanse of wings: 24 to 27 mm. Mexico (City). 
E. Infidelis Dyar is likewise allied to contrahens (21 k), but it has more monotonously brownish-grey infidelis. 
forewings, without the light apical patch and proximal margin in the basal area; both the transverse lines are 
indistinctly double, with hardly lighter fillings; the small maculae are in somewhat lighter rings and with feebly 
darker pupils; the undulate line is marked by some small dark sagittae, especially discally. Hindwing brownish- 
grey with lighter fringes. From New York. 
E. rectiflava Sm. has a dusty yellowish ground-colour with rather indistinct markings except the distinct rediflava. 
subterminal line and a blackish median shade; the transverse lines are double, the posterior line more puncti- 
form, behind it the veins are interrupted blackish, so that another double row of dots appears; before the undu¬ 
late line extends a uniform narrow brown shade, the marginal area is darker than the other ground of the wing ; 
the maculae are encircled with a somewhat darker colour. Hindwing brownish-grey. Expanse of wings: 27 mm. 
Arizona. 
E. flosca Sm. Forewing dull smoke-grey with extinct markings, difficult to distinguish by the very flosca. 
intensely strewn ground-colour; particularly the posterior transverse line is almost entirely absent; the most 
distinct of all is the yellowish undulate line being scaled darker proximad; maculae in somewhat lighter rings, 
the slightly strangulated reniform macula with some whitish scales in the lower distal angle. Hindwing smoke- 
grey. Expanse of wings: 25 to 30 mm. Arizona. It recalls somewhat E. contrahens (21 k) in its exterior. 
E. perbrunnea Grt. (21 k). Forewing purple red-brown, costal margin and marginal area more greyish- perbrunnca. 
brown, the veins strewn with white, with indistinct, on the averted sides whitish transverse lines, the distal 
line followed by black, white-dotted streaks on the veins; ring-macula indistinct, reniform macula narrow, 
black, encircled with white; the whitish undulate line is proximally bordered with brown, with dark streaks 
on the veins behind it. Hind wing brownish-grey. Canada to California. 
E. hyposcota Hnvps. (21 k) has greyish-brown forewings tinted reddish, with light grey transverse hyposcoia. 
lines, with grey and black streaks on the veins behind the distal line and small grey-ringed maculae, the reni¬ 
form macula more or less 8-shaped; the grey undulate line is proximally bordered with brownish-grey. Hindwing 
brown. Mexico to Brazil. 
E. erythropis Hnvps. is strewn darker on the deep red-brown forewing, with darker striped veins and erythropis.
