MOTHS OF THE GENUS RUPELA HEINKICH 375 



Alar expanse, 39 mm. 



Genitalia with gnatlios bandlike, the central portion widely ex- 

 panded (apronlike). Uncus with base enlarged, bulbous, covered 

 with small, papillate protuberances and with a narrow dorsal groove ; 

 apical part laterally compressed (knifelil^e), slightly humped at 

 middle; apex pointed. Harpe with basal projection from costa 

 greatly produced and fusing with membranous, minutely scobinate 

 transtilla; sacculus produced at apex into an upcurved sclerotized 

 lip from Avhich a sclerotized ridge extends upward to the costa; at 

 center of ridge a slight projection. Anellus consisting of ventral 

 plate and dorsal membrane; ventral plate with upper margin 

 broadly and deeply angulate and lateral margins deeply excavate. 

 Aedeagus heavy; basal part swollen; apex produced into a stout, 

 blunt hook. 



Type.—V.S.'NM. no. 51865. 



T]/j}e locality. — Bolivia. 



Bemarks.—DQ^QvW,^^ from one male from the National Museum 

 collection labeled as follows: "17-46-55 S. Lat., 63-5-34 Long." 



A large species easily identified by its peculiar aedeagus and uncus. 



Female unknown. 



RUPELA LUMARIA, new species 



Plate 27, Figures 17-17c 



Male. — Wings white. Fore wing with veins 11 and 12 separate; 

 4 and 5 closely approximate. Hind wing with 4 and 5 closely 

 approximate. Anal tuft yellow. 



Alar expanse, 30 mm. 



Genitalia with gnathos bandlike, slightly expanded at middle. 

 Uncus with basal part a broadly triangular, hoodlike, rugose pro- 

 jection with deep central, dorsal groove; apical part abruptly taper- 

 ing to pointed apex. Harpe with basal costal projection strongly 

 produced and fusing with finely scobinate, membranous transtilla; 

 sacculus produced into an elongately triangular, coarsely scobinate 

 projection with apex sharply pointed; apex of harpe bluntly 

 rounded. Anellus consisting of ventral plate and membranous dorsal 

 part, the latter faintly rugose. Aedeagus stout, cylindrical; apex 

 expanded and produced into three heavy claws. 



Type.—V.^.^M. no. 51866. 



Type locality.— CaviWo, Costa Eica (W. Schaus, March). 



/?ewarA,'.s.— Described from single male. Can be identified by 

 basal modification of uncus, the 3-clawed aedeagus, and the heavy, 

 triangular, scobinate projection of the sacculus. 



Female unknown.
