Dyar's original description follows: 



Eulepiste Kearfotti — Gray, with a reddish ochieous tint, brighter in an obscure 

 streak beyond cell and on submedian fold. A series of black strigae along the 

 costa and on fringe; a small dash beyond cell, and an oblique bar in submedian 

 fold beyond middle. Hind wing blackish, fringe long, pale, interlined with black- 

 ish. Below, blackish, with a pale line at the base of the fringe. Expanse, 22 mm. 



Two males from Mr. W. D. Kearfott's collection, "Yuma Co., Ariz. Desert." 



Larger than the other species of Eulepiste, and differing in the genitalia. Uncus 

 a single long spine, curving downward, opposed to a broad, concave basal plate. 

 Side pieces strap-shaped or slightly concave, curved downward, and with a distinct 

 spine on the lower angle. 



U.S. National Museum, type No. 6734. 



Male genitalia. — ^Vinculum as in pseudohirsutus. 



Tegimien as in pseudohirsutus, but commonly without emargi- 

 nation in cephalic margm of dorsal area. 



Harpe simple. Lateral aspect: costa and sacculus as in pseudohir- 

 sutus, but with central and apical portions considerably broader. 



Cucullus differing from that of pseudohirsutus in following respects: 

 rather strongly constricted near base, widening distad of constriction, 

 slightly narrowmg again toward apex, dorsal margin ^vith basal half 

 sinuate, ventral margin without dentate area; apex narrowed, strongly 

 emarginate; dorsal extremity of apex in form of sub triangular, acute 

 or subacute projection; ventral extremity of apex in form of large, 

 elongate, spinelike process curving rather strongly mesad toward apex 

 and terminating acutely or subacutely. 



Transtilla \\dth arm more broadly divergent from dorsal margin of 

 costa than in pseudohirsutus; quite variable, rather short and stout 

 to fairly long and slender. 



Uncus, gnathos, and anellus as in pseudohirsutus. 



Aedeagus similar to that of pseudohirsutus except for basal portion: 

 basal one-fifth to one-fourth more smoothly and evenly expanded, 

 curving somewhat ventrad; with small ventral expansion distad of 

 main basal expansion. 



Vesica and cornutus as in pseudohirsutus.
