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 ince])tion 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 aa its analogue on the upper surface.

Eurycreon chortalis, Qrote, Plate 5, fig. 13 <5 . 



ij 9 . — 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.
