margin shorter than usual. Venation like Hypena; primaries 13- 

 veined : 3, 4 and 5 approximate ; 4 nearer 5 at base ; cell closed ; an 

 accessory cell, from the outer extremity of which 7 and 8 are thrown 

 off from one point; 9 out of 8 to costa; 8 to apex; 10 out of the 

 upper edge of the cell opposite the inception of 6. Hind wings 

 moderately full and rounded, 8-veined ; 5 arising within 3 and 4, 

 independent, or connected by an aborted feeble veinlet with the 

 median nervure. Hind tibiae with terminal and median spurs.

Anterior wings dull olivaceous brown with a liglit purple cast. The dark 

 color of the wing extends from the base to the outer median line, beyond this 

 latter a very pale shade frosts the subterminal field and extends along costal 

 region broadly to apices. Transverse anterior line even, nearly perpendicular, 

 twice angulated, rusty ochreous with a pale preceding shade. Transverse 

 posterior line similar in appearance, not angulated, even, oblique, followed by 

 a pale shade. The inconspicuous discal dot is formed by raised scales. Sub- 

 terminal line faint, irregular, indented opposite the cell and again at submedian 

 interspace ; the line itself is dark, picked out externally by pale points. Ter- 

 minally the wing is again dark below the pale apical region ; fringes dark. 

 Hind wings fuscous, without markings, touched with whitish at anal angle ; 

 fringes darker. Beneath the wings are fuscous ; secondaries paler ; discal 

 dots perceivable. Ou the primaries a white dot on the interspace between 7 

 and 8 and the costal nervules are faintly indicated by pale scales. Head and 

 appendages and thorax concolorous with fore wings ; the third palpal joint is 

 tipped with pale scales. Under the glass there is an admixture of pale scales 

 overlying the primaries and body parts. Abdomen slender, with feeble dorsal 

 tufts, no longer than internal margin of secondaries. 



Expanse, 1.10 inch. Habitat, Philadelphia; Albany, N. Y. —

This genus is allied to Hypena and Bomolocha. From either it 

 strongly differs in the shape of the primaries : their sinuate costal 

 edge, apical production and oblique and extended external margin. 

 The relative length and position of the third palpal article are pe- 

 culiar. In the last of three Papers, partly treating of the North 

 American Deltoids, to which the above genus belongs, I have enu- 

 merated twenty genera and fifty species as referable to the Group, 

 which I follow the authors of the Wiener Verzeichniss in consider-
