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. Tlic 

 obrKjue 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.

Pliaocasiophora ? niveiguttaiia, Grote. Plate 3, fig. 15 ? 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 

 mutahilana 9 • 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 

 mutdbilana there are but faint indications of their presence. The shape 

 of the external margin of the first transverse band is diiFerent ; 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 limba being more distinctly expressed by the greater 

 extent of the pale spot on external margin above the angle which they 

 enclose. Costal pale and dark dots distinct and evident. Diflers notably from 

 mutahilana 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 mutabilaiia, with 

 distinct costal striations. 



Hahitat, Pennsylvania, 



Penthiua Blakeana, Bobinson, Plate 2, fig. 8, primary wing. 



Head and thorax brownish ; primaries with a large brown basal patch, much 

 as in fasciatana {Clemens), 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. Blaki').
