in shade between the median and subterminal space, and by short black lines on 
the veins, followed by minute white dots; a whitish powdering through the s. t. 
space, which becomes darker outwardly, shading into the deep brown terminal 
space. S. t. line very indistinct, broken, barely traceable, its course irregular. 
Fringes dark, with a grayish central line. Orbicular small, round, concolorous 
outlined in pale gray. Eeniform slightly constricted medially, concoloroms, out- 
lined by a narrow gray line. Secondaries yellow fuscous at base, becoming 
smoky outwardly, a pale line at base of fringes. Beneath brown, powdery, with 
a median line and vague discal spot on primaries. Secondaries pale basally, a 
broad dark extra median line and a small discal dot. Expands 1 inch ; 25 mm.

A single specimen from Mr. IS'eumoegen’s collection, taken by Mr. 
Meeske in 1889. 
Compared with the eastern cinereola, the present species is stouter 
in body, with narrower wings. The general scheme of maculation 
is identical, but the contrasts are much greater. While there is an 
evident resemblance there can be no danger of confusion with the 
eastern form. 
Dr. Harvey’s navia has a tuberculated front and anned fore tibiai, 
and belongs, therefore, with the Stiriin^. It may be best referred 
to Stibadium for the present. 
As Mr. Grote has recently avowed his responsibility for Dr. Har- 
vey’s species, the failure to see the obvious structural characters 
separating this species generically from cinereola, is chargeable to 
the former. 
I*liisia augiilidens n. sp.— Head, thorax and primaries bluish gray in 
ground color, with fuscous powderings. Collar with a median and subterminal 
fuscous line, and the patagise have also two rather diffuse transverse lines. Tho- 
racic tuft brown, basal abdominal tuft almost black, but with a white margin. 
Primaries with the basal line distinct, black, geminate, inwardly oblique from 
the costa. T. a. line inwardly oblique, with three feeble outcurves, outer line 
black, inner vague, and marked on the costa principally, though also traceable 
below internal vein ; the line is interrupted on the median vein, where, at the 
origin of vein 2, the greenish silver u is attached, much as in ou. A very small 
silver dot follows, but is completely and even widely separated. The median 
space is vaguely and irregularly fuscous shaded. T. p. line oblique, almost par- 
allel with the outer margin, irregularly aiid feebly angulate outwardly ; the line 
is whitish centered, the geminate defining lines fuscous. S. t. line prominent, 
black, irregularly and widely angulated and dentate, shading off by a fuscous 
tinge into the s. t. space, hut sharply contrasted against the bluish gray terminal 
space. This character forms the most obvious feature in the ornamentation. A 
fuscous shading near outer margin, forming irregular patches snbapically. 
Fringes gray, cut with fuscous. Orbicular a very vague, oval, oblique spot. 
Reniform narrow, upright concolorous, very imperfectly defined by narrow black 
lines. Secondaries yellowish fuscous basally, with a broad smoky brown outer
