minutely dotted before and beyond this spot; in male this spot small, 
triangular, more black dots beneath this, costal edge more dotted with 
black; a larger slightly inwardly oblique triangular spot on ] / 4 of dorsum, 
with acute top to fold, ending in a small tuft of raised scales, base con- 
nected anteriorly by a narrow blackish streak along dorsum with base of 
whig ; a broad transverse fascia occupying second fourth of costa, to dorsum 
just before tornus, gradually narrowed downward, margins strongly 
undulate; anterior margin edged by a row of small raised white scale-tufts, 
lower extremity of margin outwardly curved; less than apical fourth of 
wing black, edge slightly oblique above and below, in middle erected into 
a wedge-shaped, slightly oblique projection merging into central fascia

dilated below, hook ending in a round plate. Valva with a narrow basal 
half, cucullus abruptly dilated and angulate below, top gradually nar- 
rowed; valva densely bristled, bristles gradually becoming large spikes 
anteriorly, a separate group of such spikes in middle of disc; sacculus with 
a brush of extremely long bristles. Aedoeagus moderate. Anellus and juxta
