dark marginal band. Expanse of wings: 30 mm. From Greenland. 
E. luteosita Sm. (7 h) is greyish-yellow, in the discal area reddish-brown and dusted with blackish, luteosiia. 
with distinct transverse lines similarly arranged as in bifasciata, and with large, somewhat lighter maculae; 
the faded median shade is more distinct in the $; undulate line marked by black, small sagittae on the inside. 
Hindwing brownish-grey, towards the base lighter, with a dark discal spot and yellowish fringes. From Colorado. 
E. dissona Moschl. (= rara Pack.) (7 i) is very variable, light grey with a lilac tint, dusted brownish dissona.

Morr. (= labradoriensis Stgr.) (7 h) has been dealt with in the palearctic part Vol. Ill, p. 32, t. 6 i. Light grey, 
very characteristic by a black basal ray as far as the anterior transverse line, continued into the coniform macula 
which is filled up with black and from the apex of which a black stripe extends to the posterior transverse line. 
From Greenland, Labrador, and Mt. Washington. —• The dark brown larva exhibits a whitish, interrupted 
dorsal line and subdorsal lines. 
E. munis Grt. (= sublatis Grt.) (7 i) is very much like dissona, but larger and more intensely marked, the munis.

E. rena Sm. (7 i) is likewise allied to the two preceding species, it is more of a violettish grey, on the rcna.

of dots, the maculae in lighter rings and surrounded with black, between them the cell is black. Hindwing

the maculae is reddish or brown, not black; median line present. From Canada (Montana, Vancouver, Calgary). 
E. divergens Wkr. {= versipellis Grt.) (7 i) is more purple brown with a costal streak strewn with divergens. 
light grey, a black basal ray and white-striped median and base of the subcostal; the black transverse lines are 
bordered with grey on the averted sides; the maculae in grey rings and surrounded with black, between them 
the cell is black, also behind them as far as the posterior transverse line; undulate line light grey. Hindwing 
brownish, towards the base lighter. Canada to Colorado and California. — The larva is dirty grey, somewhat 
diaphanous, on the dorsal and ventral sides somewhat lighter; it lives polyphagous on many low plants. — 
ab. fusimacula Sm. has confluent maculae and between them no black-filled cell. — f. abar Streck. (= factoris fusimacula. 
Sm.) is towards the base and margin lighter reddish-grey, only in the discal area darker red-brown with distinctly abar.

E. henrietta Sm. (7 i) somewhat resembles the more variegated forms of the palearctic obelisca (Vol. Ill, Henrietta. 
t. 5 h); brownish-grey with a lighter costal-marginal part; the cell and the space behind it as far as the post¬ 
median line dusted with brown; a black, broad basal ray is present; transverse lines dentate, on the averted 
sides bordered with grey; the maculae are in whitish rings and surrounded with black, the ring-macula oblique 
oval, above open; the marginal cell-spaces are striped blackish. Hindwing white, dusted withbrownish. Distri¬

E. delicata B. & McD. is a very small species with purple red forewings with distinct, dentate, delicata. 
single black transverse stripes; the maculae are surrounded with black and pupilled with oclireous-yellow scales; 
the faintly yellowish undulate line defines the darker marginal area. Hindwing dirty whitish with brownish 
veins. Expanse of wings: 28 mm. Described according to a $ from California. 
E. obeliscoides Gn. (— sexatilis Grt.) (8 a) is very much like henrietta (7 i), but it has more chestnut- obeliseoidcs,
