Male. — Palpi, head, and thorax pale fuscous, sparsely sprinkled 

 with white ; posterior margin of thorax edged with blackish fuscous. 

 Fore wing dull white, sparsely sprinkled with fuscous and with a very 

 pale fuscous stain in a broad area bordering imier margin ; antemedial 

 line angulate, fuscous, rather faint but complete and always distin- 

 guishable; subterminal line double, consisting of two parallel, faint, 

 pale-fuscous lines, almost vertical and but very slightly dentate ; discal 

 spot at end of cell blackish fuscous, prominent ; a row of small blackish 

 dots along termen between the vein ends. Hind wing whitish with a 

 very pale fuscous line edging termen. 



Alar expanse, 15-18 mm. 



Genitalia (figs. 16-16c) much smaller than those of either hihinda 

 or polingella; basal portion of aedeagus narrower in proportion; 

 harpe with apex more bluntly rounded than that of polingella but 

 with width of harpe less in proportion to its length than that of 

 hihinda. 



Female. — In color, markings, and palpal structures similar to the 

 male. Pubescence of antenna much shorter. 



Alar expanse, 16-20 mm. 



Genitalia (fig. 52) with signum similar to that of Cahela fondero- 

 sella.^ the inwardly projecting edge not appreciably serrate ; sclerotized 

 plates in genital opening very weak, hardly distinguishable except 

 under very liigh magnification. 



Larvae. — Solitary in habit, white, not banded or conspicuously 

 spotted. 



Type. — In Rutgers College collection. 



Tyjye locality. — Texas. 



Food plant. — Opuntia {Oylindroptmtia) leptocaulis De CandoUe.

 San Antonio; Florida (one female, so labeled and without other lo- 

 cality, from the Fernald collection in the United States National 

 Museum) . 



Seventeen specimens examined. 



Remarlis. — The labial palpus of the male is somewhat misleading. 

 In natural position the third segment is projected forward as in 

 fig. 104 ; but in relaxed and badly prepared specimens it may be bent
