E. cinerascens Sm. (10 i) is lighter than the preceding, greyer, the posterior transverse line is distinctly dnerascen #. 
dentate, the macula darker brown, in grey rings and surrounded with black; the indistinct undulate line is 
grey, proximally bordered with a darker brownish-grey, the darkest below the costal margin. Hindwing greyish- 
brown with whitish fringes. Washington and California. 
E. wockei Mschlr. Head and thorax chestnut-brown, collar striped whitish, at the end black. Forewing wockei. 
greyish-brown, in the discal area dusted reddish with finely dentate single transverse lines, the cell filled up 
with black and grey maculae in it, the ring-macula V-shaped, above open, the reniform macula inwards pro¬ 
duced on the median, the long grey coniform macula surrounded with black; undulate line quite indistinct. 
Hindwing light greyish-brown with a darker discal luna and transverse line behind it. The $ is greyer without 
the reddish tint. Labrador, New Hampshire, known also from the palearctic region. 
E. scropulana Morr. (= westermanni Hmps.) (8 b) is quite similar, more variegated, lilac grey and scropulana. 
chestnut-red, with a black wedge-shaped spot before the coniform macula. From Greenland and Canada. — 
The form moschleri B.-Hacis (13 g) is still more contrastingly coloured and marked. moschleri. 
E. cinerea Stgr. (= okakensis Pack.) (TO i) has formerly been confounded with the following tecta, cinerea. 
Compared with tecta, it is on an average smaller, scpiater, greyer, the postmedian line always very near to the 
undulate line, so that the intermediate area is very narrow; hindwing darker with a more distinct discal luna 
and postmedian line. The main difference are the different genitals as Dampf stated (Berk Ent. Zeitschr. 1909, 
p. 128). It is mostly overlooked that of cinerea there also occur forms with a reddish-brown tint and of tecta 
greyer forms, so that the colouring alone is not a certain mark of distinction. Labrador, also from Mt. Washington 
(New Hampshire). 
E. tecta Hbn. ( = carnea auct.) (10 k) is marked the same as cinerea, generally somewhat larger teda. 
and of a brighter reddish brown; as to the difference we refer to what has been said in cmerea. •—- roosta Sm. roosta. 
is a much more variegated form of a brighter ferruginous red colour from Alaska. According to recent examina¬ 
tions by Dr. Corti it is very doubtful whether the palearctic tecta occurs at all in America, in which case the 
name would have to be replaced by roosta. 
E. terrifica Sm. (10 k) is likewise very similar, more slender, with narrower wings, more whitish, tcrrifica. 
strervn with a brownish grey, with white hindwings being only somewhat brownish at the costal margin. Co¬ 
lorado. 
E. quadrangula Zett. (= rava H.-Schaff., umbrata Pack.) (10 h, and Vol. Ill, t. 12 e) is darker and quadrangu- 
of a more monotonous greyish-brown, more densely strewn with dark, otherwise very similarly marked as 
the preceding, but with a smaller, rounder, closed ring-macula. Hindwing dark brownish-grey with yellowish- 
white fringes. Greenland, Labrador, Nova Scotia, also found in Iceland (comp. Vol. Ill, p. 52). 
E. flavicosta Wallgr. (= magellanica Btlr.) (10 g). Large, red-brown with an ochreous-yellowish flavicosta. 
costal-marginal stripe and equally coloured maculae being confluent with it; the transverse stripes are quite 
indistinct, the posterior stripe dentate. Hindwing light reddish-brown with lighter yellowish fringes. From 
Patagonia. 
E. castra Schs. (10 k) is a very different insect and very easily recognizable by the yellowish- castra. 
white ground-colour with the long black longitudinal ray and two black cellular dots above it. Brazil (Castro, 
Parana). 
E. rufisigna Hmps. is ochreous-whitish, scantily strewn with black, without transverse lines; the ring- mfisigna. 
macula is a black dot, the reniform macula quadrangular, red-brown, surrounded with black, indented on the 
median; the apex of the wing is parted by an oblique, faded red-brown shade; on the margin there are black 
dots. The whitish hindwing is tinted reddish-brown with a darker discal dot. Expanse of wings: 52 mm. South 
Eastern Peru. 
E. cirphioides Schs. is similar to rufisigna, much smaller, of a somewhat more reddish tint, with a cirphioides. 
faint dark basal ray, the median and the lower radial branch are finely dark olive-brown; the reniform macula 
is round, more blackish grey; the postmedian line is marked by dark brown dots on the veins; the marginal 
area is shaded with brownish, with black marginal dots, an oblique subapical shade and a dark stripe below 
the lower radial branch; above the maculae dark costal-marginal shades. Hindwing white, at the costal margin 
and apex brownish-grey. Expanse of wings: 32 mm. Costa Rica (Juan Vinas). 
E. glaucochroa Dogn. is likewise very similar to rufisigna, of a more greenish-oclireous tint, smaller, glaucochroa. 
with entirely white hindwings in •both sexes, and a reniform, not quadrangular distal macula. Expanse of wings: 
42 to 45 mm. South Eastern Peru. 
E. tiniloides Dogn. (S = sagitta Dogn.) (10 k). The $ is brownish-grey with a white median and iiniloides. 
dark brown other veins on each side striped grey; the inner-marginal and distal-marginal area dusted reddish, 
with a black basal ray, discal spot and postmedian dots on the veins; the apex of the wing is parted by a 
somewhat darker shade, another shade being situate above the anal angle. Hindwing diaphanous white with 
dark marginal dots. The $ has a more straw-coloured ground-colour with but slightly darkened veins and a 
reddish-brown stripe in the lower cell-end and more distinct brown spots of the marginal area. Ecuador (Loja),
