Fresh specimens show a distinct olivaceous shading on primaries 
which is rather liable to fade leaving the brown hues more prominent, 
especially in the basal area. The characteristic features of the species 
are found in the subterminal brown area which is less jagged on its 
outer margin than in basiflava Pack. and also more suffused and de- 
fined outwardly more or less distinctly with whitish; the prominent 
dark dashes and the white supra-anal spot are wanting. The t. a. line 
in ¢ has usually a very prominent outward angle in the cell. We 
append Grote & Robinson’s description of the ? as being more satis- 
factory than Walker’s, and have added a description of the 3 by 
ourselves. 
“®. Evenly olivaceous-cinereous, very sparsely irrorate with black scales. 
Transverse lines pale brown. Inner median line irregularly dentate, brown. A 
brown discoidal streak around which the scales are faintly and irregularly paler 
than elsewhere. Outer median line nearly straight and even, brown, shaped 
much as in P. Clintonii, but with still less prominent inflections and succeeded 
by a similarly colored rather paler brown shade band, which is equally wide 
but rather more diffuse superiorly, where it is faintly margined with paler scales. 
A terminal brown line further from the margin and more irregular than in 
P. Clintonii. 
Secondaries pale grayish-brown, darker than in P. Clintonii; a diffuse 
darker subterminal shade band and very faint discoloration. 
Under surface slightly darker than upper surface of secondaries. On 
anterior wings a faint, discal, darker discoloration and a discontinued, oblique, 
even, subterminal, shade band. On the secondaries a discal undefined spot and 
a distinct, even, oblique dark band crossing the wing from within the apex to 
anal angle. This band runs within and at variance with its analogue on the 
upper surface, as can be seen by holding the specimen to the light; its obliquity 
and peculiarity has suggested the specific name. On the primaries, also, the 
subterminal band is not produced immediately beneath the outer median line. 
Head, thorax and appendages covered with mixed grey scales. Abdomen 
paler than secondaries. Exp. 2 2.00 inches. Length of body, 0.85 inch.

The more simple ornamentation of this species will quickly distinguish it 
from Parorgyia Clintonii nob. The male is unknown to us.” G. & R. 
¢@. Smaller and darker than 9, strongly tinged with olivaceous in fresh 
specimens; a dark basal half-line; basal space to t. a. line largely brown, tinged 
with olivaceous along costa and inner margin; t. a. line irregular, dentate, with 
three outward projections,—in the cell, in the submedian fold and above the 
inner margin—preceded by a rather indistinct white parallel line; median space 
shaded with white around reniform, which is fairly distinctly outlined in deep 
brown; t. p. line slightly waved, rather evenly outcurved from costa to below 
cell, then incurved in submedian fold and bent outward at inner margin; sub- 
terminal space suffused brown, shaded with olivaceous, bordered by an indistinct,
