EUXOA. By Dr. M. DratjdT. 
cletesta. fornia. — f. detesta Smith (7 f) is a much lighter form, yellowish greyish-white, dusted with brown, with a 
mostly more distinct marking. Washington, Colorado. 
abnormis. E. abnormis Sm. (7 e) is very similar to intrusa (7 e), lighter, more reddish grey with less contras¬ 
tingly light maculae, the anterior transverse line double, the posterior line single; the reniform macula is pupilled 
leaden-grey, intrusa with a little yellowish, the median shade being absent. Hind wing more dirty greyish-brown 
with a dark discal spot. California. 
noctuifor- E. noctuiformis Sm. (7 f) is drab, on the collar with a black median line; the forewing with double 
VUS! - transverse lines and large maculae in light rings and surrounded with black, the cell before and between them 
darkened; there is a median shade being broken on the median; marginal area darkened, before it the light, 
proximally dark undulate line. Hindwing yellowish brown. Washington, California. 
pleuritica. E. pleuritica Grt. has red-brown forewings with a yellowish reflection, at the costal margin and in 
the proximal part more greyish-brown, dusted with whitish. Transverse lines double, filled up with a lighter 
colour, the posterior line only marked by dots on the veins, and with grey maculae surrounded with black; 
undulate line whitish. Hindwing brownish, towards the margin darker. Canada to California. 
pestula. E. pestula Sm. Ground-colour brownish yellow, bluish-grey, strewn with brown and black except 
the yellowish basal area; transverse lines all double, frequently filled up with a lighter colour, also a median 
shade is distinct; maculae large, light grey in a darkened ground; undulate line light, before it a darker costal- 
marginal spot, behind it the marginal area is darkened except the apex which remains light. Hindwing yellowish, 
distally smoky. Expanse of wings: 31 to 37 mm. Alberta (Canada) 
declarata. E. declarata Wkr. (= decolor Morr.) (7 g) was united with tessellata by Hampson, but Barnes and 
Me Dunnough have stated (Canad. Entomol. L [1918] p. 194) that this is probably not correct. At any rate 
this species and the following offer a great deal of difficulties that have not yet been solved. It is certainly 
a fact that 2 extremely similar species, though with different genitals, have been mixed up with each other. 
The present species has purple brown wings with a reddish tint, remarkably large maculae and light hindwings. 
In the S genital organ the appendices of the harps are equably long and form almost a U. Canada (Vancouver) 
and United States. 
campesiris. E. campestris Grt. (7 g, h) is the second, nomenclaturally somewhat doubtful species, with very dark 
purple brown wings without any other tints, with small maculae and darker hindwings. The proximal continua¬ 
tion of the harp is shorter, the distal one at the base not so uniformly rounded and much longer. Canada to 
Colorado. — The larva is brown, somewhat transparent with lighter dorsal, subdorsal and lateral lines, and 
lives polyphagous on low plants. 
verticalis. E. verticalis Grt. (7 f) is similarly marked as the preceding species, but lighter and more variegated, 
lilac-grey with a mostly reddish costal part; the anterior transverse lines are double, filled up with whitish, 
the posterior line only at the costal margin double, otherwise single, sharply dentate; the large maculae in 
lighter rings are situate in the blackened cell, from the lower angle of which a median shade extends to the 
proximal margin; before the light undulate line there is a dark triangular spot at the costal margin, behind it 
spectanda. the margin is darkened. Hindwings of a pure white. Colorado, California. — f. spectanda Sm. with a more distinct 
and clearer marking, smaller maculae, and still lighter, lustrous white hindwings is an insignificant form from 
Colorado. 
albipennis. E. albipennis Grt. ($ = nigripennis Grt.) (7 g) has yellowish-brown forewings dusted with grey and 
a contrastingly dark brownish-black thorax; the markings are entirely like in verticalis, the costal area is dar¬ 
kened. Hindwing white with a fine brown marginal line. The $ is much darker, purple black, the hindwing 
malis. also dark brownish-grey with white fringes. From Canada to California. — f. malis Sm. (= indensa Sm.) (7 g) 
is a more bluish-grey form, the discal area scantily dusted with reddish, and with a faded posterior transverse 
bialba. line. From Canada. — In f. bialba Sm. from Dakota and Utah the $ is not darker, but coloured like the 
and the hindwing is also only very slightly brownish. 
colata. E. colata Grt. (7 g) is a large, likewise quite dark species, purple brown, scantily strewn with grey, 
with quite indistinct transverse lines, and a black ground before and between the equally coloured maculae 
which are finely surrounded with black. Hindwing monotonously dark brown. Oregon, California. 
lewisi. E. lewisi Grt. (7 li) is smaller than the preceding similar species, more red-brown with likewise indi¬ 
stinct transverse lines, the posterior line dentate, the maculae in grey rings and surrounded with black in a 
deep black ground; the undulate line is more distinct, light, finely dentate. Hindwing lighter brown with whitish 
fringes. Colorado. 
trifasciata. E. trifasciata Sm. in the marking resembles bifasciata (7 b), but the forewing is darker red-brown, 
strewn with a bluish grey, and with distinct, large maculae encircled with blak, partly grey, the reniform macula 
laterally strewn with yellow; between both the dark median shade passes through and approaches the rather 
indistinct, more faded posterior transverse line below the cell; undulate line light, punctiform. Hind wing brow n- 
ish-grey. Expanse of wings: 37 mm. Oregon, from Mt. Hood.
