rior tibial spurs as cliaraclcriziiig the group "■ Ephtjrkl(c'\ It diilers from 

 Epiupa in the palpi being much longer, the third joint projecting far beyond the 

 head, while the fore wings are much longer, more acute, and the hind wings are 

 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 fifth 

 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.

 Both wings crossed by tw^o 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.

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 

 serrate hind wings, the })ointed primaries, and the two wavy, curved, dark 

 lines. It is marked beneath much as in Ephyra mijrtaria Guende.
