the narrower interspace is Y-shaped towards internal angle, enclosing by the 
inverted limbs a dark spot. A series of costal ante-apical dark dots. The 
oblique outer band encloses a paler ill defined space on external margin above 
the angle. Hind wings dark fuscous with pale fringes. Beneath paler, with 
the central portion of the fore wings fuscous. 
Habitat, New York; Pennsylvania; Virginia. 
Phaecasiophora? niveiguttana, Grote. Plate 2, fig. 15 9 primary wing. 
Although I only know the female of this species, there seems but little 
doubt that it belongs here, since it agrees in all apparent characters with 
mutabilana ¢. The ornamentation is so similar that it is best described com- 
paratively. Bright ochreous, the darker markings reddish brown. The 
darker bands are more attenuate, sinuous, defined by blackish scales, distinct. 
Two blackish streaks at the base of the wing are quite evident, whereas in 
mutabilana there are but faint indications of their presence. The shape 
of the external margin of the first transverse band is different; it is acutely 
projected about the subcostal nervure, lunulate beneath. The white discal 
spot on the middle band is clear, distinct and defined; there is a black dot (on 
the succeeding pale interspace) which, owing to the outward angulation of the 
middle band where it encloses the white discal spot, appears above this latter 
on the costal region. The outer band is like an inverted Y, owing to its nar- 
rower shape, and the limbs being more distinctly expressed by the greater 
extent of the pale spot oh external margin above the angle which they 
enclose. Costal pale and dark dots distinct and evident. Differs notably from 
mutabilana by the presence of two white apical streaks, the one, shorter, 
before the apex, the other longer, below it and attaining the extremity of the 
upper limb of the Y-shaped outer band on external margin. Hind wings 
fuscous. Beneath both pair are pale fuscous, darker than in mutabilana, with 
distinct costal striations. 
Habitat, Pennsylvania. 
Penthina Blakeana, Robinson, Plate 2, fig. 8, primary wing. 
Head and thorax brownish; primaries with a large brown basal patch, much 
as in fasciatana (Olemens), from which this species differs by the twice broader 
whitish succeeding interspace which has a faint pink hue, and by its width 
narrows the median dark brown oblique continuous band of the wing which is 
toothed outwardly at the center. Costal points distinct ; the apical darker 
shading is reduced and limited by a curved shade line. Hind wings fuscous 
with pale fringes. Fore wings with the fringes tipped with dark scales to 
about the middle of external margin. 
Habitat, Pennsylvania (C. A. Blake).
