THE CACTUS-FEEDING PHYCITINAE HEINRICH 399 



shaded and spotted with dark grayish fuscous, the kiteous tint pro- 

 nounced on basal third of costa and over the submedian area of the 

 wing ; transverse antemedial and subterminal lines obsolete ; a fuscous 

 shade from costa before middle to cell, another from costa at middle, 

 and below these corresponding streaks or spots on lower vein of cell 

 and vein lb ; a thin blackish line on the fold from its base to near its 

 middle ; a similar dark streak on vein lb at outer third ; short, broken, 

 dark streaks on the veins at or near the cell ; a clouded fuscous spot 

 at end of cell; outer half of costa shaded with fuscous; a row of dark 

 spots along termen at or very close to the vein ends. Hind wing 

 white, semihyaline with only the faintest indication of a fuscous line 

 on termen toward apex. 



Alar expanse, 32-45 mm. 



Genitalia (figs. 38-38d) agreeing in size and nearly all details with 

 those of longipennella except that the arms of the anellus are a trifle 

 longer in niaculifera. 



Fevidle. — In color and pattern like the male except that there is 

 some gray shading on the head and thorax and considerably more 

 gray on the fore wing (the single specimen before me is in much 

 better condition than the males, which may account for some of the 

 differences) ; basal third of wing clouded with dark fuscous; termi- 

 nal area more faintly clouded; subterminal line faintly indicated, 

 sharply angulate at middle, broken below; the luteous shade more 

 contrasted than in the male, but restricted to middle of cell and the 

 area between veins lb and the fold. Hind wing white, semihyaline 

 with a narrow fuscous shade along termen and on the veins near 

 their apices. 



Alar expanse, 37 mm. 



Genitalia (figs. 75-75a) similar to those of insignatella but with 

 sclerotized ventral plate in ductus bursae at genital opening smaller. 



Type. — In United States National Museum. 



Type locality. — Oaxaca, Mexico. 



Food plant. — Unknown. 



Distribution. — Mexico: Oaxaca., Salina Cruz (Sept.). 



Eight specimens examined. 



Remarks. — This species may be distinguished from other species of 

 Cactohrosis by the strong luteous (pale clay) shade on the fore wing 

 and the serrate-fasciculate male antenna.
