The species as far as I know is limited to the United States. 

 Hitherto specimens have been identified as albinella Cramer. It can 

 be identified at once by its peculiar aedeagus and female genital 

 plate. 



RUPELA SCITULA, new species 

 I'LATB 26, Figures 15-15c 



Male. — Wings shining Avliite. Fore wing with veins 11 and 12 

 separate; 4 and 5 approximate or connate. Hind wing with 4 and 

 5 stalked. Anal tuft white. 



Alar expanse, 21-29 mm. 



Genitalia with gnathos beaklike ; lateral arms well developed ; basal 

 projecting part truncate; apical part tapering to pointed apex; in- 

 ner surface sparsely and very finely scobinate. Uncus with basal 

 part bilobed but rather small as compared with other species, the 

 lobes bearing several short spines on dorsum; apical part long, 

 tapering to pointed apex. Harpe with basal process of costa slightly 

 produced; apex bluntly rounded; sacculiis produced into a narrow, 

 elongate fold at apex, otherwise simple. Anellus consisting of 

 ventral plate and a partially sclerotized dorsal band, the latter 

 bearing one pair of very long, stout spines and a pair of much 

 thinner and shorter spines; lateral margins of ventral plate nar- 

 rowly but deeply excurvate. Aedeagus with apex deeply l)ut nar- 

 rowly excavate on under side and bearing several short, stout^, 

 ventral spines. Tegumen vpith sharp, projecting spur {Tgsp) from 

 each inner lateral margin. 



Tijpe and paratype. — U.S.N.M. no. 51864. Paratypes also in Cor- 

 nell University collection and British Museum. 



Type locality. — Tucuman, Argentina, 



Remarlcs. — Described from male type and seven male paratjqies, 

 the paratypes distributed as follows: On boat from Mexico (Quar- 

 antine no. Phila. 27764), one; Brazil, Obydos (E. E. Austin, Febru- 

 ary 2, 1896), one, Rio Janunda ("11-4-47"), two; British Guiana, 

 Mackenzie. Demerara (W. T. M. Forbes, June 23-24, 1927), tlu-ee. 



^fay be identified at once by the shape of the uncus, the spining 

 of the dorsal part of the anellus, and the spurs on the tegumen. 



Female unknown.

Plate 27, Figures 16-16c
