THE CACTUS-FEEDING PHYCITINAE HEINRICH 393 



Genitalia (figs. 35-35c) with apical process of gnathos small; end 

 of vinculum bluntly angulate. 



Female. — Color and markings as in the male. 



Alar expanse, 27-30 mm. 



Genitalia (figs. 65-65a) with signum a single, weak, irregular, 

 thornlike patch; bursa copulatrix wrinkled and finely scobinate; 

 ductus bursae coarsely scobinate toward bursa. 



Type. — In United States National Museum. 



Type locality. — La Rioja, Argentina. 



Food plant. — Cereus validus Haworth. 



Distribution. — ^Argentina: Rioja., La Rioja; Santiago del Estro. 



Three specimens (one male and two females) examined. 



Remarks. — The moth is easily identified by the clear yellow inner 

 area of the fore wing. The larvae feed in the fruits and flower buds 

 and, possibly, to some extent, in the stems of Cereus. Dodd states 

 that they also attack fruits of Platypmitias. 



7. OZAMIA PUNICANS, new species 



Plates 32, 40 ; Figures 32-32c, 61-61a 



Male. — Palpi fuscous sprinkled with white. Head and thorax 

 fuscous heavily dusted with white and more or less shaded with pale 

 rust color, especially on top of head and on collar of thorax. Fore 

 wing pale gray (fuscous heavily dusted with white) marked with 

 darker gray and with large blotches of pale rust color; the rust 

 shade filling about one-fourth of the basal area and nearly all the area 

 between antemedial and subterminal lines, lower vein of cell, vein 2, 

 and vein lb; antemedial line obscure, indicated chiefly by a rather 

 broad dark-gray shade from costa to lower vein of cell and a thin 

 dark-gray line thence to inner margin ; subterminal line faint, some- 

 what sinuate but not dentate, approximately parallel with termen, 

 bordered inwardly and outwardly by obscure dark gray ; apical mark 

 at end of cell irregular, dark gray ; between cell and subterminal line 

 some faint rust shading in the interspaces between the veins; a row 

 of black dots along termen between the vein ends ; cilia pale rust-red. 

 Hind wing white, semihyaline, with a fuscous shade in costal area to 

 top of cell and vein 8, some fuscous shading on the vein ends, and a 

 fine fuscous line along termen to vein lb ; cilia shiny white. Abdom- 

 inal tufts as in hemilutella. 



Alar expanse, 36-38 mm. 



Genitalia (figs. 32-32c) with apical process of gnathos moderately 

 large ; apex of harpe more rounded than in other species of Ozamia; 

 end of vinculum more rounded than angulate and lateral margins 

 excavate ; penis bearing a number of coarse spines.
