Habitat. — Arizona. 



One $ (Tepper) and one 9 (Neum.). The species is very distinct from 

 all others with the same structural characters, and is nearest to acclivis 

 Morr. At first sight there isn suggestion of herelis in the habitus of 

 the species which may mislead. The simple $ antennjc are distinctive. 



A. albicosta Smith, sp. nov. 



Structural characters as in procUvis, the terminal armature of fore 

 tibia heavier. The side piece of S is long, narrow, oblique at tip, the 

 upper angle long drawn out, the inner side closely spined. TLie clasper 

 is short, stout, dilated at middle, and with a short beak-like curve at tip. 

 Primaries very dark smoky brown ; basal dash and cell, except ordi- 

 nary spots, black. Costal space and ordinary spots pale luteous. T. a. 

 line indicated between median and s. m. vein, else obsolete. T. p. line 

 obsolete. S. t. line indicated only by a few indefinite black marks op- 

 jjosite the cell. Orbicular round, small, with punctiform dark center. 

 Reniforui normal, annulate with somewhat paler yellow. Secondaries 

 pearly white with smoky outer border. Beneath, ])rimaries blackish, 

 secondaries pearly white. Tborax concolorous with i)riniaries, some- 

 what purplish. Expands 1.25 inches (31-32''""). 



JIabitat. — Arizona. 



A neatly marked and easily recognized species. There is nothing 

 like it with the same structural characters. A male specimen from Mr. 

 iN'euraoegen furnished the type ; others $ and 9 from various collec- 

 tions, in single specimens, have been since seen, and agree with the type 

 specimen. 



A. oblongistigma Smith, n. sp. 



Anterior tibia spinose, moderately armed at tip ; clypeus with a small, 

 roughened protuberance depressed in the center. Tuftings of thorax 

 small, iiulefiuite; collar with a narrow black line. Primaries smoky 

 brown or blackish, cell between ordinary spots darker ; costal region and 

 ordinary spots dull ash gray; an oblique subapical gray shade; a sub- 

 median gray shade from center of wing nearly to hind angle. Median 

 vein marked with white; on veins 3 and 4 two sagittate pale rays cross 

 the s. t. space and indent the s. t. line. Transverse lines wanting; s. t. 

 line ])ale, distinct, tolerably even, except on veins 3 and 4, preceded by 

 distinct black sagittate dashes. A narrow black basal dash ; claviforni 

 long, concolorous, narrowly outlined in black. Orbicular oblique, ob- 

 long, superiorly opening into the pale costal region. Reni form upright,
