Transverse posterior line blackish, well removed towards external margin 
leaving the middle field of the wing wide. It differs by running nearly 
straightly downwards from its inception which takes place nearer the apices 
than usual. It is minutely undulate or subdentate to vein 2, below which 
it is inwardly arcuate, and nearly even to internal margin. A very fine 
continuous line margins the wing. Fringes concolorous. Secondaries paler, 
somewhat testaceous, clouded faintly centrally with blackish. A single 
continued narrow blackish line, continuous with the transverse posterior 
line of the primaries, crosses the wing. It is minutely undulate and becomes 
irregularly rivulous inferiorly. The external margin and fringes are more 
or less stained with light brown, and colored like the fore wings. A similar 
fine marginal line borders the wing. Body parts concolorous with primaries. 
Beneath a little paler and duller tinted. A faint discal streak on primaries, 
none apparent on the hind wings. A common exterior distinct blackish 
transverse line, which, on the hind wings, is better marked, and not so irreg- 
ularly rivulous inferiorly as its analogue on the upper surface.

Eurycreon chortalis, Grote, Plate 5, fig. 132. 
é @.—Head with a frontal projection. Palpi short. Fore wings with the 
costal edge somewhat convex and with the apices depressedly acuminate. 
Pale testaceous much shaded with gray, varying in depth of tint and dis- 
tinctness of markings. Fore wings testaceous,dusted with gray. The veins 
marked with dusky scales colored like the lines. Discal dots and two inner 
transverse lines difficult to make out. Transverse posterior line evident, 
acutely dentate on interspaces, continued. Subterminal line similar but 
more even and equally apparent, becoming a little diffuse at apices. A nar- 
row terminal line. Fringes concolorous, with dark lines, of which the 
inner is sometimes interrupted. Hind wings white, with a more or less 
continued and expressed blackish transverse line running at variance with 
the more distinct diffuse black serrulate subterminal band which widens to 
apices and becomes narrow and obliterate toward anal angle. The narrow 
terminal space between this band and the margin is stained with testaceous; 
a continued terminal line. Fringes whitish outwardly, dark near the wing, 
with the inner line apparent. Both the apices of the fore and hind wings 
are, in one specimen, touched with ochreous. Beneath more dusky, but like 
upper surface, all the markings are repeated, veins dusky; on hind wings 
there is a discal liture, and the inner.transverse line is-seen to run inwardly 
opposite the discal streak. The wings are subopalescent and diaphanous.
