NORTH AMERICAN LEPIDOPTERA. 55 



line geminate, black, included space concolorous, marked only on the costa and 

 siihmcdian interspace. T. a. line {leminate, black, interrupted, inner defining 

 line vague, outwardly oblicjne and outcurved in the interspace, so that it reaches 

 the hind margin at about its middle. T. p. line geminate, the inner line black- 

 ish and lunulate, interrupted on the veins, the outer line fuscous, indefinite. A 

 vague median shade line, black-marked on the costa, but scarcely traceable else- 

 where until it reaches the inner margin. The s. t. space is rather paler than the 

 rest of the wing, and the s. t. line is prominent, pale, marked with whitish scales 

 preceded by large, blackish fuscous sagittate spots. The line is rather even, save 

 that it is variably indented on veins 3 and 4 by whitish rays on tliesc veins. 

 There are less marked whitish rays on veins 7 and 8 as well, which do not indent 

 the line. There is a series of black terminal lunules preceding a pale terminal 

 line. The fringes are paler than the ground color, with a fuscous interline and 

 cut with fuscous at their tips. The claviform is black-marked, concolorous, va- 

 riable in size. Orbicular irregularly oval, variable in size, black ringed, then 

 annulate with whitish, centre of the ground color. Reniform irregular, out- 

 wardly expanded inferiorly, black margined, then annulate with white, cen- 

 trally filled by a black powdering, much more prominent inferiorly. Secondaries 

 dull luteous, more whitish and partly transparent basally, more fuscous out- 

 wardly. Fringes paler, with a darker interline. Discal lunule visible. Beneath 

 paler, more whitish, fuscous powdered, both pairs of wings with an outer line 

 and a discal lunule, the primaries, in addition, a dusky s. t. line. Eicpauds 35- 

 40 m. ; 1.60 inches.

One male and two female specimens are before me, from the smaller 

 of which the figure was made. There is another among the mate- 

 rial for deterniination in the collection of the American Entomo- 

 logical Society. The species cannot be positively referred to its 

 proper group in the genus until the genitalia of the male have been 

 examined, but it has the habitus of ehartarla or defessa. The sagit- 

 tate subterminal marks give the insects a marked resend)lance to 

 Hadena devastatrix, not in any way lessened by the rather promi- 

 nently whitish marked reniform. 



iVIaiiieMfra listdeiiiloriniN n. sp. (PI. v, fig. 4)— Ground color a pale 

 sordid luteous gray, with hhick powderings. Collar with an indefined broad 

 luteous band. Thoracic vestiture with black scales intermixed, forming an in- 

 definite marginal line. The dorsal tufts are small but evident, divided. Prima- 

 ries with a deeper ashen gray shade along the inner margin, and through the 

 terminal space, the transverse maculation indistinct. Basal line geminate, 

 darker gray, with somewhat paler included space, angulated on the median vein, 

 very little relieved. T. a. line geminate, defining lines scarcely darker, included 

 space of ground color outcurved in the interspaces, with difHcnlty traceable. T. 

 p. line geminate on costa and inner niaigin, between which points the outer line 

 is obsolete, the inner only feebly defined, darker gray, accompanied by a narrow 

 white line, crenulated, irregularly bisinuate. A somewhat diffuse median shade, 

 darkening the reniform and close to the t. p. line below it. 8. t. line distinct,
