218 LEPIDOPTERA OF NORTH AMERICA. 



DREPANA SCHE. 



Body very slender. Proboscis not visible. Palpi very short, 

 not extending beyond the head. Antennae longer than the thorax. 

 Abdomen not extending so far as the hind wings. Legs slender, 

 bare, hind tibiae with four rather short spurs. Wings broad. Pri- 

 maries falcate, slightly convex along the costa, undulating or in- 

 dented along the exterior border ; interior angle rounded ; discal 

 areolet intersected by a secondary vein ; second inferior vein more 

 than twice further from the third than from the first ; third not 

 further from the fourth than from the second. Male. Antennae 

 moderately pectinated. Female. Antennas very minutely pecti- 

 nated, much longer than those of the male. 



1. D. fasciata Steph. Uncula Haw. 



Wings brownish-yellow; anterior with two oblique brown striae, 

 bent towards the costa ; the posterior one with a brown cloud at-

2. D. arcuata Walk. C. B. M. VIII. 



Male. Pale testaceous. Antennae with brown branches. Fore 

 wings very falcate, with brown oblique streaks along the costa ; 

 with two slender zigzag brown bands near the base, with two dark- 

 brown discal dots, and with three exterior brown bands ; the first 

 and the third of the latter slight and undulating ; the second dark- 

 er, more 'distinct, and nearly straight, ending at the tip of the 

 wing, which is pale brown in front and gray behind, excepting the 

 extreme tip, which is wholly dark brown. Hind wings with seve- 

 ral indistinct tawny undulating bands, and with two minute brown 

 discal dots. Length of the body 4 lines ; of the wings 15 lines. 



This species closely resembles D. falcataria in form and color 

 and markings, but may be distinguished by its more falcate fore 

 wings, by the more oblique second exterior band, by the less 

 numerous and less distinct bands of the hind wings, and by other 

 differences.
