NORTH AMERICAN LEPIDOPTERA. 55 



thence slightly oblique outwardly to iuternal vein and along outward curve 

 below. T. p line geminate, outcurved over reniform, then nearly parallel with 

 outer niarjiiu ; inner line narrow, crenulate. distinct, outer line even, much less 

 evident. S. t. line narrow, pale, sinuate, marked by the darker terminal space. 

 A series of black terminal lunules and a yellow line at base of fringes. Clavi- 

 form moderate in size, concolorous, distinctly outlined in black. Orbicular 

 moderate in size, slightly irregular, but hardly oblique, distinctly black ringed, 

 and with a very narrow border of pale scales ; reniform moderate in size, of the 

 normal form, with a paler central line. Secondaries ( 9 ) white, the veins dark 

 marked. Beneath white, primaries somewhat smoky and with a trace of an 

 outer line. Expands 1.32 inches; 33 mm. 



Habitat. — California ( Neunioegen ). 

 ^ A single female only of this pretty and sharply defined species is 

 at hand. It has all the appearance and structural peculiarities of 

 the tessellata group ; the white secondaries of the 9 ^Ily it with pal- 

 llpennis, while the niaculation of primaries is n)uch more like albi- 

 pennis, or even dedarata. Some cleanly marked specimens of tes- 

 sellata resemble this species, but the white secondaries are always 

 distinctive. Had the specimen been a male the white secondaries 

 would not have been so important, as the female may have dusky 

 secondaries when those of the % are white ; the reverse, however, is 

 never the case within my experience. 



A. nostra sp. nov. — General color a somewhat luteous brown, varying a 

 little in shade. Sides of palpi darker, the front sometimes with dark scales. 

 Collar with a somewhat faintly marked median transverse line. Thoracic tuft- 

 iugs gray tipped, sometimes the entire thorax somewhat darker in shade than 

 the ground color. Costal region powdered with gray, more broadly at base, 

 terminal space blackish, not greatly contrasting, and somewhat variable in the 

 amount of. the dark shading ; on apical blotch gray powdered. Basal line present, 

 geminate, not well marked. T. a. line geminate, very slightly oblique, with a 

 distinct outward curvature in the interspaces ; the line is sometimes barely 

 traceable, and the two parts are generally equally distinct. T. p. line neai'ly 

 parallel with the outer margin, the inner line finely crenulated, outer line re- 

 duced to a row of small venular dots which are sometimes wanting; sometimes 

 the entire line is scarcely traceable. S. t. line irregular, concolorous, marked 

 only by the dusky terminal space and by a vague preceding shade ; a series 

 of small terminal lunules. Claviform indefinitely outlined, concolorous. 

 Orbicular oval, of good size, black ringed, gray powdered ; reniform large, 

 kidney shaped, narrowly black ringed, concolorous or slightly paler, somewhat 

 leaden filled inferiorly. The spots are always distinct, but somewhat variable 

 in point of definition, sometimes incompletely outlined. The space between 

 the spots is darker, but never black or prominent. One specimen shows a black 

 spot preceding the orbicular, and another has the entire niaculation obscured, 

 the grmind color paler than normal. Secondaries smoky fuscous, the veins
