AMERICAN LEPIDOPTERA. 103 



over m. nervules and is more even than usual. Basal whitish line sometimes 

 apparent. Subterminal line white, angulate, appearing interlaced with t. p. 

 line and reminding us of Cidaria atricolorata. Expanse, 26 to 30 m. m. 

 Habitat. — Same localities with the preceding. 



Hypena bijugalis, Walker. — % 9 . — Primaries with a brown basal patch 

 like H. baltimoralis, than which this is a somewhat smaller species. The t. p. 

 line is distinctively shaped ; it is nearly perpendicular, twice scalloped, pro- 

 jected most prominently and shortly over median nervules. Subterminal line 

 an undulated series of distinct dots. Following the t. p. line the wing is palest 

 shaded; in dark specimens with a violet wash. Varies in tint. Expanse, 21 

 to 31 m. m. 



Habitat. — Eastern, Middle and Southern States. 



Hypena manalis. Walker. — % 9 . — Smaller than the preceding species. 

 A median oblique olive brown patch extending downwardly from costa, mar- 

 gined inwardly by the even strongly outward oblique t. a. line, and outwardly 

 by t. p. line, which is similar to t. a. line in appearance, but roundedly project- 

 ed over m. nervules, thence inwardly oblique nearly joining t. a. line at lower 

 angle of the median patch. Elsewhere the primaries show a purplish reflec- 

 tion. Subapical blotches or dash very obvious. S. t. line dotted. A minute 

 raised scale dot on the cell, in place of orbicular, on the dark patch. Expanse, 

 23 to 25 m. m. 



Habitat. — Canada, New York; altogether rarer than the preceding 

 and our prettiest species. 



Hypena madefactalis, Guenee. — % 9- — •*■ broad winged species, 

 colored like the foregoing, but less intensely and brightly. Primaries olivace- 

 ous brown to t. p. line which is nearly perpendicular, continued, a little waved, 

 variable in evenness. The t. a. line perceptable, not pale like the t. p. line but 

 darker shaded than basal space. Orbicular dot more or less evident. T. p. 

 line followed by purplish washings. Subapical blotches variable in distinctness. 

 Subterminal shades and lines inconspicuous. Beneath wing and body are 

 ochrey tinted, former with obsolete markings. Expanse, 30 to 32 m. m. 



Habitat. — New York, Pennsylvania, Virginia. 



Guenee describes from a figure of Abbot's. I think this is the species 

 intended, but there are slight discrepancies in the two descriptions. 



Hypeua toreuta, Grote. — (=internalis \\ Robinson.) 

 This species is described in a previous paper. Mr. Robinson's des- 

 criptive term had been used by Guenee for another species. With 

 the succeeding the external margin of primaries is unusually rounded. 



Hypena sordidula, Grote. — % .— Size and color and form of H. toreuta. 

 Sooty black, powdered with grey scales. The ordinary lines are faintly ap- 

 parent, nearly perpendiclar, brought into relief by pale powderings, waved or 

 undulate. T. p. line usually marked by pale scales on costa. Several ante-
