rior liliial spurs as characterizing the group "Ephyrida". It differs from 

 Ephyra in the palpi being much lunger, the third joint projecting far beyond the 



head, while the tore wings are much longer, more acute, and the hind wings an; 

 rather longer, fuller, and rounder at the apex, and delicately scalloped. The 

 wings are thinner and the moth slighter and more delicate than in Ephyra, 

 its nearest ally. The venation differs from that of Ephyra mainly in the filth 

 subcostal venule arising just within the origin of the first subcostal but on the 

 opposite side of the main vein. Unfortunately, the male has not yet occurred, 

 so that this diagnosis must be quite imperfect.

4 9 . — Pale reddish-ash-brown ; head and palpi clearer, pale reddish-brown. 

 Both wings crossed by two remote dark hair-lines, sinuate and wavy, the inner 

 acutely angulated on the costa, and indented on the median vein. An outer 

 line curved considerably outward between the costa and lowermost branch of 

 the median vein, the line most of its length parallel to the outer edge. Discal 

 dot distinct, oval, white, circled with dull rust-red on the fore wings, with a 

 darker circle on the hind wings. Fringe long, concolorous with the wings, 

 with a black line at base. Beneath, with minute discal white dots. Wings 

 paler than above, not speckled with brown, clear, with a single, common, 

 outer, curved line, and a dark line at base of the fringe. 



Length of body, 9,0.30; of fore wing, 9,0.33-0.40; expanse of wings, 

 0.77 inch.

This moth may be distinguished from the species of Ephyra, to which it 

 is allied in its coloration and style of marking, by the delicately-scalloped or 

 senate hind wings, the pointed primaries, and the two wavy, curved, dark 

 lines. It is marked beneath much as in Ephyra myrtaria Guenee.
