margin in Homocoprepes but strong in Nanodacna; vein 10 is approxi- 
mately equidistant from 9 and 11 in Nanodacna but much nearer to 
9 than to 11 in Homoeoprepes. 
In venation, the hind wings of Homoeoprepes and Nanodacna are 
essentially the same. Although the hind wing of Nanodacna is 
lanceolate, shape cannot be used for generic distinction in this case 
as can be demonstrated by the two different hind-wing forms in the 
closely related species of Homoeoprepes described below. 
FHomoeoprepes appears to favor high altitudes and, undoubtedly, 
more species of this genus remain to be discovered in the Neo- 
tropical region.

The moth was described from an imperfect female as previously 
indicated, but the genitalia of this specimen were not included in the 
description and are as follows: Ostium moderately large, oval. Ductus 
bursae membranous except for a sclerotized section near middle; 
inception of ductus seminalis near junction of ductus bursae and bursa 
copulatrix. Bursa copulatrix longer than ductus bursae; signa two 
elongate sclerotized plates each with central dentate process.

Labial palpus ocherous white with slight pinkish reflections on inner

segment with fuscous subapical annulus. Antenna grayish fuscous 
with narrow, paler annulations; scape fuscous above, mixed with few
