394 PROCEEDINGS OF THE NATIONAL MUSEUM vol.86 



Female. — Color and markings as in the male. 



Alar expanse, 38-40 mm. 



Genitalia (figs. 61-61a) larger than those of any other Ozamia; 

 with signum a small granulose plate containing a stubby central 

 thorn ; bursa copulatrix wrinkled and finely scobinate ; ductus bursae 

 long, very coarsely scobinate toward bursa. 



Type and paratypes. — U.S.N.M. no. 52755. Paratypes also sent to 

 Mr. Dodd. 



Type locality. — Tapia, Tucuman, Argentina. 



Food plant. — Cereus validus Haworth. 



Remarks. — Described from male type and two male and four fe- 

 male paratj'pes from the type locality and reared by R. C. Mundell 

 October 19, 23, 25, 28, 29, and 31, 1936, and October 17, 1933, from 

 larvae boring in the stems of Cerevji validus. 



According to Dodd punican^ differs from other species of Ozamia 

 in that it is a stem borer and apparently does not attack the fruits or 

 flower buds. It differs also in that the apex of the harpe is not defi- 

 nitely oblique, and the maxillary palpi are somewhat narrowly scaled. 

 However, the latter are of the squamous rather than the filiform 

 type, and from its general habitus the species is obviously closely 

 related to hemilutella. The moth can be easily identified by the 

 rust-red cilia and blotches on the fore wing. 



17. Genus CACTOBROSIS Dyar 



Cactobrosis Dyab, Proc. U. S. Nat. Mus., vol. 47, p. 406, 1915; Proc. Ent. Soc 

 Washington, vol. 30, p. 135, 1928. (Genotype: Moodna eJongatella 

 Hampson.) 



Antenna of male with a series of modified, papillalike setae on the 

 inner sides of several basal segments of the shaft, bipectinate {fer- 

 naldialis, longipennella) or strongly serrate and pubescent {maculi- 

 fera., strigalis) ; antenna of female simple and shortly pubescent. 

 Labial palpus upturned in the male, oblique in the female. Maxil- 

 lary palpus filiform (fig. 134a). Hind wing with veins 7 and 8 

 anastomosing beyond the cell ; 3 and 5 shortly stalked. Eighth ab- 

 dominal segment bearing a pair of ventrolateral hair tufts (the tufts 

 long and dense except in strigalis). 



Male genitalia with apex of gnathos large, bifid; apex of harpe 

 evenly rounded; vinculum long (moderately long in strigalis); 

 anellus with base of plate narrowly sclerotized, arms long, slender, 

 slightly twisted; aedeagus long, stout (shorter and less stout in 

 strigalis) ; penis more or less densely pubescent (armed with short 

 hairlike spines).
