AMERICAN LEPIDOPTERA. 183 



by two faint, darker streaks, the inception of a median, geminate, 

 transverse shade, which runs approximately to the transverse posteri- 

 or line, but which is very faint and partially obsolete. Transverse pos- 

 terior line, geminate, arcuate opposite the disc, formed by a double se- 

 ries of dull, pale greenish lunules, which, opposite the disc, are mixed 

 with black scales, the whole faint. Costa with three black, distinct, 

 preapical dots. A faint, subterminal, blackish shade, inwardly den- 

 tate, on the interspaces superiorly, medially obsolete, inferiorly ap- 

 pearing as a distinct, black, uneven V-shaped mark. Terminally the 

 wing is obscure olivaceous, this darker color interrupted between first 

 and second median nervules by the paler greenish, olivaceous color of 

 the median space, which here extends to external margin. A termi- 

 minal interrupted line everywhere preceded by a narrow, coincident, 

 pale shade. Nervules marked with black scales. Fringes, pale oliva- 

 ceous, interrupted with darker scales at extremity of the nervules. 

 Secondaries, smoky grey. A median undulated line followed by a co- 

 incident whitish shade line. Between this latter and external mar- 

 gin the wing is evenly darker colored than elsewhere. Fringes, pale 

 grey, interrupted with dark scales at the nervular extremities. An 

 obscure dark terminal line. 



Beneath, with obsolete ornamentation. Primaries, whitish at base 

 and along internal margin, terminally and below costa, dull blackish. 

 The preapical black dots reproduced. Nervules marked with blackish. 

 The subterminal shade of upper surface is here indicated. A very dis- 

 tinct, blackish, even, terminal line. Secondaries almost entirely whit- 

 ish; fringes, darker, and prominently interrupted with blackish scales. 



$ . Resembles the male. Antennae, simple and shorter. Abdo- 

 men, plumper, and the preanal subdorsal stains of the male are obso- 

 lete. Under surface of secondaries, prominently darker, more dusted 

 with cinereous scales than in the male, while generally more obscurely 

 colored. 



Expanse, % 9, 1.80—1.90 inch. Length of hod y, 0.85 — 0.95 

 inch. 



Habitat. — Atlantic District. (New York! to Pennsylvania!) 

 We have examined four % and one $ specimens of this species. 

 The characters to be observed are : The dark thoracic discal squama- 

 tion ; the pale whitish-green primaries, having the median space and 

 the wing generally, outside of the transverse, anterior geminate line, 

 free from any admixture of dark scales in the ground color; the com- 

 paratively dark abdomen, and, in the female, the shortish antennae.
