MOTHS OF THE GENUS RUPELA HEIXRICH 365 



Type locality.— Duviiwgo, Mexico (C. C. Hoffman, "276"). 



Remarks. — Described from type and one paratype from the type 

 locality, one paratype from Colima, Mexico (Schaus, collector), one 

 paratype from Jalapa, Mexico (Schaus), and one paratype from 

 Cabima, Panama (A. Busck, May 20, 1911). 



The species may be recognized by the characteristic spining of the 

 dorsal part of the anelliis and the line of fine cornuti on the penis. 

 Only two of the species treated in this paper show any trace of 

 cornuti or a cornutus. 



Female unknown. 



RUPELA PALLIDULA, new species 



Pi^iTE 23, Figures 5-5<Z 



Male. — Head and palpi as in the pure white species. Thorax 

 white but with collar darker, concolorous with fore wing. Fore 

 wing silvery buff, unicolorous; cilia snow white; veins 11 and 12 

 separate; 4 and 5 stalked. Hind wing darker than fore wing, gray 

 to grayish broAvn, cilia snow white; veins 4 and 5 stalked. Wings 

 concolorous beneath, grayish broAvn. Anal tuft white. 



Alar expanse, 24-32 mm. 



Genitalia with gnathos beaklike but with lateral arms well de- 

 veloped; basal, projecting part rather narrow, truncate; inner sur- 

 face very finely scobinate; apex upturned. Uncus with basal part 

 humped, subquadrate, rather deeply grooved posteriorly and some- 

 what rugose; apical half digitate, laterally compressed on dorsum 

 at apex. Harpe tapering slightly at apex; apex rounded; basal 

 process of costa greatly produced, digitate (the basal processes of 

 the two harpes united by a bit of membrane at tlieir apices) ; sac- 

 culus produced at apex into a minute spine. Anellus consisting of 

 ventral plate and dorsal membrane, the latter bearing two pairs of 

 short, stout spines; ventral plate broadly incised on upper margin, 

 lateral margins concave. Aedeagus witli a pronounced lateral spur 

 at apex. 



Type and paratypes. — U.S.N.M. no. 51858. Paratypes also in 

 British Museum. 



Type locality. — Castro, Parana, Brazil. 



Remarhs. — Described from male type and 12 male paratypes from 

 the type locality and 1 male paratype from Sao Paulo, Brazil. 



The above were in the National Museum collection and British 

 Museum, identified as tinctella \Yalker. The species is easily recog- 

 nized by its color, the spining of the anellus, and its characteristic 

 aedeagus. 



Female unknown, probably white.
