Adult (fig. 19). — Wing expanse: cf , 12-20 mm.; 9, 12-17 mm. 



Head: Fuscous, irrorated with ^^hite; apices of most scales 

 whitish. Antennae fuscous, faintly ringed with white; scales of scape 

 with whitish apices. Labial palpi not sexually dimorphic, of approxi- 

 mately same size in male and female; second segment about 1.25 

 X length of third; subascending, fuscous, irrorated with white, usually 

 with more white present on inner surface as compared to lateral 

 surface; apex of terminal segment tipped with white. 



Thorax: Fuscous, irrorated with white; anterior third or fourth 

 darker, scales mostly fuscous; i)osterior two-thirds distinctly paler, 

 scales mostly whitish; undersides of thorax considerably paler, 

 whitish. Pro- and meso thoracic legs fuscous, irrorated with white; 

 apices of tibial and tarsal segments faintly ringed with white; meta- 

 thoracic legs paler, whitish; banding on tarsal segments only slightly 

 discernible. Forewings of approximately same color as head; trans- 

 verse band at wing base dark, outer margin sharply defined by paler 

 scales; a white, often crescent-shaped patch of scales present at apex 

 of cell; marginal fringe fuscous, with a scattering of white-tipped 

 scales. Hindwings uniformly gray; veins 3 and 4 normally stalked 

 approximately one-third their length; occasionally connate. 



Abdomen: Grayish white above and below, with a lateral band of 

 fuscous extending the entire length of the abdomen on either side. 



Male genitalia (figs. 67-68). — Uncus reduced to a small, setig- 

 erous rounded lobe. Tegumen reduced, forming a relatively narrow 

 dorsal ring. Transtilla well developed, arched, often thickened at 

 middle to form a rounded lobe projecting ventrally and caudad. Valvae 

 variously lobed, usually with four distinct projections, three of which 

 arise apically and one near middle; median apical lobe digitate, greatly 

 exceeding other lobes in length. Juxta broad, peltate, firmly attached 

 to base of valvae. Vinculum and saccus well developed, variable in 

 form, Y- to V-shaped. Aedeagus clavate, apical end enlarged with an 

 elongate, obhque patch of approximately 15-25 stout cornuti; in- 

 ception of ejaculatory duct near middle. 



Female genitalia (figs. 85, 104).— Ovipositor relatively long; 

 posterior apophyses approximately 1.5 X length of anterior pair. 

 Lamella antevaginalis subtriangular, apex of triangle rounded and 

 directed caudad; posterior margin mostly entire, slightly sinuate 

 laterally; lamella postvaginalis consisting of a darkly sclerotized ring 

 bordering posterior margin of lamella antevaginalis; ring thickened
