E. lixiva Grt. (= numa Drc. part.) (52 g) like the following species, has shorter palpi and is faintly 
ochreous reddish on forewings slightly peppered with blackish and with a large narrow cuneiform black-brown 
mark hr central area. This is conjoined with a costal spot by a thin streak. Both are outlined delicately by 
black with silvery white edges. The two transverse lines are barely indicated, brownish, the subterminal line 
is more darkly shaded and there is a blackish costal spot in front at the top. Hindwings brownish. Arizona, 
Mexico (Durango). 
E. basicinerea Grt. (52 h) differs from the previous species by a grey basal half, browner outer half and 
a somewhat more narrow velvety black central band, that is not expanded to the same extent, especially at 
inner margin and which is conjoined at costa with 2 smaller spots. Reniform stigma is larger and paler. Arizona. 
E. antonita Dyar (52 h) closely resembles the previous and subsequent species. Basal area of forewings 
pale grey, outer area reddish brown, the two colours being separated by a narrow black band that extends to 
the costa. It is concave in the cell and below, so that a dentation is formed in the centre towards the base on 
the inner side. This may be interrupted on submedian. Reniform stigma with paler surround. Hindwings 
blackish brown. Texas. 
E. orthozona Damps. (= santarita Dyar) (52 h). Differs from the preceding by the ochreous grey basal 
area, the outer area is only slightly less reddish, the middle band is wide with fine silvery white edge, slightly 
narrower in the cell, inner margin slightly incurved below cell. Hindwings reddish grey-brown. Texas. 
E. anita Dyar (52 h) forms a group of closely related species with the preceding and following forms 
and they are difficult to differentiate. Basal area pearly grey, the narrow central band is somewhat constricted 
in cell and on inner marginal nervure and is edged with whitish. Outer area dull brownish. Costa spotted alter¬ 
nately ochreous and black. Reniform stigma circular and ochreous. Subterminal line heavily undulate and 
ochreous with dark spot on inner side on costa. Posteriorly a fine black marginal line. Fringes grey. Hind¬ 
wings yellow-grey. Mexico (Orizaba). 
E. victrix Dyar (52 h). The black central band is wider, more deeply incurved twice on inner side and 
with faint and paler edge. Outer area ochre-yellow, dusted with olive-grey. Reniform stigma large, ochreous 
free of olive-grey dusting. The partially obsolete subterminal line is dark, it commences at a triangular costal 
spot and has 2 more distinct projections. Fringes black, intersected with ochreous in centre and subapically. 
Hindwings brownish. Mexico (Orizaba). 
E. inveterata Dyar (52 h). The entire forewing is more monotonous, darker grey, the outer area being 
the same colour. The curved central band wide to middle of cell, contracting from there and being very narrow 
at costa. Margin and fringes narrowly black, intersected in centre by grey. Reniform stigma a dark dot. Of 
the subterminal line only a dark subapical spot is present. Hindwings grey-brown. Mexico (Teliuacan). 
E. melor Dyar (52 h). Basal area grey, outer area ochreous, shaded with blackish beyond the some¬ 
what paler elliptical reniform stigma. The black central band is very wide, contracting towards the costa, 
outwardly somewhat concave in centre, edged on both sides with silvery white. The irregular pale subterminal 
line is situate in the dark marginal shading, which becomes gradually darker until dissolving into the black 
fringes. Hindwings whitish in <§, grey in $. Mexico (Cuernavaca, Morelos). 
E. melorista Dyar (52 h) differs from the preceding species by the somewhat darker grey basal area, 
a fine orange line anterior to the white inner edge of the wide central band. Outer area is orange with a brown 
dusted margin in which the silvery white subterminal line is situated. Anteriorly on costa there are two minute 
black spots with a further one on submedian. Fringes dark grey with a pale patch in centre. Hindwings mono¬ 
tonous black-brown. Mexico, Guerrero (Iguala). 
E. dissociata Dyar (52 h) is somewhat larger than the preceding, paler grey in basal area, clay-yellow 
in the outer two thirds. A triangular blackish spot at base of costa with a further smaller and more narrow 
spot posteriorly. Central band wide, widely triangular on costa, constricted in cell, becoming extremely narrow 
at inner margin. Reniform stigma is a pale ellipse in nebulous grey and with grey centre. On margin 2 olive- 
grey nebulous patches. Hindwings dark grey. Mexico (Teliuacan). 
E. lixinites Dyar (52 h). Pale grey at base, the black central band very wide at inner margin, terminating 
suddenly in cell in a rounded point. Outer area ochre, peppered with grey outwardly and with pale circum¬ 
scribed reniform stigma. The black subterminal line is widest at costa, marginal line pale. Fringes black in 
centre and at anal angle. Hindwings grey. Mexico (Oaxaca). 
E. megaplaga Dyar (52 i). Grey shaded with olive-brown. The black central band is developed into 
a large almost quadrate inner marginal spot, to which a more or less pronounced dark triangular costal spot 
is joined outwardly at its apex. Reniform stigma with pale centre having up to 3 dark dots. The faint pale 
subterminal line has a very wide dark shade inwardly. On margin there are 2 protracted dark semicircular 
marks. Hindwings grey-brown. Mexico (Teliuacan).
