NORTH AMERICAN l.EPIDOPTERA. 79 



S. t. line paler gray, rather even, with little outward teeth on veins 3 and 4, pre- 

 ceded by a more or less marked blackish shade, broken into spots, and followed 

 by a blackish shade which may be broken into spots or may be continuous and 

 fill much the greater part of the terminal space. A series of black terminal lu- 

 nules, preceded and emphasized by a creuulated white preceded line. Fringes 

 gray, marked with fuscous lunules. A vague, incomplete, median shade line, 

 darkening the cell between the ordinary spots, thence obsolete, to reappear again 

 below the claviform. Claviform moderate or small, wide, black margined, with 

 a luteous tinge. Orbicular large, round, black-ringed, concolorous or paler. 

 Reniform large, broadly kidney-shaped, black-ringed, concolorous or paler, cen- 

 trally with a darker lunule. Secondaries white, with a more or less evident, 

 but always faint luteous tinge. A black discal spot, a more or less continuous 

 powdery median line and a broken blackish terminal line. Beneath white, pow- 

 dery. All wings with a distinct, round, blackish discal spot, a more or less com- 

 plete extra median line, and a broken terminal line. Expands 34-3(j mm.: 1.36- 

 1.44 inches.

Three male specimens are before me, and I have seen others. The 

 antennfB are pectinated, and the species is thus related to hiemalis 

 and peritalw, most nearly to the latter. In fact, T considered it a 

 variety at first, and so named it for Messrs. Strecker and Neumoegen. 

 Additional material shows no nearer approach to typical peritaUs, 

 but emphasizes the difference, and I nmst therefore regard it as dis- 

 tinct. It differs in the much more evident transverse maculation, 

 the want of a black basal dash, the sordid tinging in the ground 

 color, and, finally, in having the antennal branches somewhat longer. 

 Withal the relationship is not distant. 



XyloiiiigeM caiidifla n. sp. (PL v, fig. 1) -Ashen-gray with black jiow- 

 derings. Collar with an inconspicuous blackish median line. Patagiaj with a 

 broader snbmarginal line, dorsum with blackish powderings intermixed. Pri- 

 maries with all the transverse macnlations present. Basal line geminate, black 

 with rather long, acute, outward angulations in the costa and in the submedian 

 interspace. Above the submedian vein the basal space is quite considerably 

 darkened by the black powderings. T. a. line geminate, the inner line lost in 

 the dark powderings of the basal space, outer line black, as a whole upright, with 

 a small outward angulation over the costa, a more prominent one in the subme- 

 dian interspace, and a moderate outcurve below vein 1. T. p. line geminate, 

 outer line even, rather indefinite, inner line crennlate; as a whole the line is 

 rather evenly bisinuate, the included space paler than ground color. A broad, 

 somewhat difl^use black median shade extends obliquely from costa through the 

 cell, darkening the reniform inferiorly and then forming a broad black margin 

 to the inner portion of the t. p. line. S. t. line even, faintly marked, paler, em- 

 phasized by a series of preceding black spots. Fringes irregular, smoky, a series 

 of small black dots at base, and with small pale rays over the veins, not extend- 

 ing to the margin. The veins are all more or less black marked. Claviform
