MOTHS OF THE GENUS RUPELA HEINRICH 383 



Remarks. — Described from three females, the paratypes distributed 

 as follows: Panama, Rio Trinidad (June), one; Costa Rica, Gua- 

 piles (March), one. 



RUPELA MAENAS, new species 



Plate 31, Figures 36, 37 



Wings white. Fore wing with veins 11 and 12 approximate; 4 

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

 connate or shortly stalked. Anal tuft yellow. 



Alar expanse, 22-31 mm. 



Genitalia with ductus bursae strongly sclerotized, brown and ex- 

 panded into a laterally flattened bulb near genital opening. Genital 

 plate developed as a narrow hoodlike piece in front and a broad, 

 hooked, truncate flange behind genital opening (see pi. 31, fig. 36), 

 the flange protruding from the area between the ventrolateral mar- 

 gins of the eighth segment collar. Genital opening nearly circular. 



Type and paratypes. — ^U.S.N.M, no. 51903. Paratypes also in 

 British Museum and Cornell University collections. 



Type locality. — Ponte Nova (Rio Xingu), Brazil. 



Remarks. — Described from eight females, the paratypes distrib- 

 uted as follows: French Guiana, St. Laurent Maroni (March), one; 

 British Guiana, Kartabo (October), one, Mackenzie (June), two; 

 Surinam, Zanderij (April), two; Brazil, Castro (Parana), one. 



Easily identified by the bulbous, sclerotized ductus. I suspect it 

 may be the female of horridida. 



RUPELA NEREIS, new species 



Plate 31, Figures 33, 34 



Wings white. Fore wing with veins 11 and 12 separate; 4 and 

 5 connate. Hind wing with 4 and 5 connate. Anal tuft yellow. 



Alar expanse, 40 mm. 



Genitalia with ductus bursae brown, sclerotized and tubular toward 

 genital opening. Genital plate consisting of a pair of narrow lateral 

 flaps extending backward from margin of genital opening and fusing 

 with a flanged and hooked process, which protrudes between the 

 ventrolateral margins of the eighth segment collar; strongly sclero- 

 tized, brown ; apex of protruding flange abruptly tapering to a blunt 

 point. Ventral area between collar and ovipositor strongly sclero- 

 tized, developed as a pair of elongate, shallow, somewhat rugose 

 depressions. Genital opening semicircular. 



Type. — In British Museum. 



Type locality. — Castro, Parana, Brazil. 



Remarks. — Described from one female.
