3 as that vein is from the cell end, sub-medican and internal veins straisht • wino- 

 slightly longer than broad, somewhat circular in shape, the costa, apex and outer 

 margin being evenly rounded, slightly emarginate at the end of vein 2. Antennte 

 long, much as in Zampa ; palpi curved upwards against the face, second joint densely 

 hairy, third hidden ; hind tibiae heavily fringed and with two pairs of spurs. 



The secondary sexual character consists of an oblique linear glandular streak of 

 very thick scales on the upperside of the forewing, from aljout the middle of the 

 sub-median vein to a little 1)efore the base of vein 3, the lower portion of the streak in 

 the sub-median interspace is nearly upright, and divided into two by the iutcrnervular
