Bondia fuscata, new species 



Figures 21, 66, 86, 105, 122; Map 9 



Adult (fig. 21). — Wing expanse: cf, 11-16 mm.; 9, 14-19 mm. 



Head: Fuscous, irrorated with white; majority of scales white 

 tipped. Antennae fuscous, indistinctly ringed with pale gray; scales 

 of scape white tipped. Labial palpi not sexually dimorphic, of ap- 

 proximately same size in male and female; second segment about 

 1.25 X length of third; subascending, almost entirely fuscous, except 

 for interior surfaces which are strongly irrorated with white; apex of 

 terminal segment typically with a few white to grayish white-tipped 

 scales. 



Thorax: Fuscous to black, faintly irrorated with white to pale 

 gray; ventral surfaces considerably paler, whitish. Pro- and meso- 

 thoracic legs fuscous with slight irroration of white; metathoracic 

 leg paler in color; tibial hairs whitish; tarsal segments faintly ringed 

 with pale gray. Forew^ngs similar to dorsum of thorax in color, dark 

 fuscous slightly irrorated with pale gray; pattern rather uniform over 

 entire wing except for presence of faint, crescent-shaped patch of 

 whitish scales occasionally present at apex of discal cell; fringe with 

 mixture of fuscous and grayish white scales tipped with white. Hind- 

 wings uniformly gray; veins 3 and 4 stalked approximately one-third 

 their length. 



Abdomen: Uniformly pale gray above, more whitish below. 



Male genitalia (fig. 66). — Uncus reduced, consisting of a small 

 conical lobe possessing either an entire or minutely clefted apex. 

 Tegumen reduced to a relatively narrow dorsal arch. Transtilla rel- 

 atively well developed, posterior margin evenly curved. Valvae broad 

 at base, abruptly narrowing to form an acute, curved, apical lobe. 

 Juxta broad, somewhat diamond-shaped. Vinculum and saccus well 

 developed, V-shaped. Aedeagus claviform; apex with a dense, linear 

 patch of 15-20 stout cornuti; juncture of ejaculatory duct near middle. 



Female genitalia (figs. 86, 105). — Ovipositor relatively long; 

 posterior apophyses twice the length of anterior pair. Posterior margin 

 of lamella antevaginalis slightly curved, almost truncate. Lamella 

 postvaginalis with a prominent ridge extending medially and partially 

 encircling a low, broadly conical lobe which arises medially just caudad 

 of posterior margin of lamella antevaginalis. Ductus bursae entirely 

 membranous, narrow beyond constriction of sinus vaginalis, gradually 

 enlarging to form relatively narrow and elongate corpus bursae. 

 Origin of ductus seminalis near caudal end of ductus bursae.
