MOTHS OF THE GEKUS RUPELA HEII^RICH 371 



in any of the other specimens and the clasper had a short secondary 

 spine branching from its base. These differences are probably but 

 individual abnormalities and, in my opinion, do not justify any 

 separate name (varietal or otherwise) for the Castro specimen. 

 The female is unknown. 



RUPELA VEXATIVA, new species 



Plate 25, Figubes 11-llc 



Male. — Wings pure white. Fore wing witli veins 4 and 5 connate ; 

 11 anastomosing with 12. Hind wing with 4 and 5 very shortly 

 stalked. Anal tuft white. 



Alar expanse, 27 nun. 



Genitalia wdth gnathos beaklike, triangular, cleft from apex to 

 middle. Uncus broad at base, tapering sharply to pointed and 

 slightly hooked apex; basal part extended backward as a bulbous 

 lobe (cowllike) ; dorsal surface of lobe with a few weak, scattered 

 scobinations. Harpe with cucullus somewhat broadened toward 

 apex; apex rounded; basal process of costa long, digitate; saccuius 

 produced into clasper, the latter, a strong, stout spine, curved up- 

 Avard to costa. Anellus consisting of a rigid ventral plate and dorsal 

 membrane; plate somewhat constricted at middle, lateral margins 

 deeply incurved; membrane but slightly rugose, weakly sclerotized. 

 Aedeagus smooth, bulging laterally just beyond middle, thence tap- 

 ering rather abruptly toward apex ; apex spatulate. 



Type. — In Britisli Museum. 



Type locality. — Quirigua, Guatemala. 



Remarks. — Described from one male collected bv Wm. Schaus 

 (April). 



This species is easily recognized by its peculiar aedeagus, its cleft, 

 triangular gnathos, and its strong, curved, hooklike clasper. 



Female unknown. 



RUPELA CORNIGERA, new species 

 Plate 25, Fi(iui:Es Vl-Vlh 



Male. — Wings white. The wings are not so bright as in most of 

 the other species, but their dullness may be due to the condition 

 of the specimens. Under side of fore wing faintly dark shaded 

 in costal area; veins 11 and 12 separate; 4 and 5 connate or shortly 

 stalked. Hind wing with 4 and 5 connate or shortly stalked. Anal 

 tuft w^iite. 



Alar expanse, 27-30 mm. 



Genitalia with gnathos beaklike, tapering abruptly to middle, and 

 gradually from middle to bluntly rounded apex. Uncus stout, basal 

 part very broad and with central rib; apical two-thirds digitate;
