arated, one of them at end of discal cell; often, a similarly colored 

 tuft of raised scales basad and dorsad from this fascia, and another 

 one between it and termen. Sometimes an ochreous ray along discal 

 cell, interrupted at middle fascia and almost reaching termen. Some- 

 times some of veins darker than ground of forewings, Costa with 

 dark gray spots; terminal line black, undulate. Above markings not 

 present in each specimen, and varjdng in their development and 

 combination. Cilia concolorous with ground of forewings, or some- 

 what paler. Under side of forewings more or less dark brownish 

 gray, sometimes with whitish and blackish costal spots. Length 

 of forewing, 11-14 mm. Hind wings pale fumose with grayish brown 

 reticulation; cilia concolorous with ground or slightly paler with 

 dark-gray basal line, sometimes with a dividing line. 



Male genitalia. — Tegumen slightly excavated at tip, without 

 cristae; gnathos broad ^^^Lthout any spiculation; socii decumbent, 

 elongate, broadly lanceolate. Valvae narrowed apicad; brachiola 

 rather large; sacculus drawn out into a more or less long acute or 

 blunt point before half, sometimes with small additional thornlike 

 projections before this point, then cm^ving costad sharply and strongly, 

 forming a large rotundate ventral excavation, and descending to a 

 more or less sharply pointed tip directed downward; apical tuft 

 moderate. Aedoeagus strongly curved, stout at base, then tapering; 

 vesica \vith a cluster of four to eight cornuti capitate at base, and a 

 stout robust thornlike apical cornutus dilated basad. 



Female genitalia. — Sterigma with strongly dilated, then tapering 

 lateral lobes with tipes more or less acute and usually curved. An- 

 trum w^de and long, bifurcate cephalad, sclerotized especially caudad. 

 Ductus bursae slightly longer than cervix bursae, almost as broad as 

 antrum, somewhat narrowed cephalad. Cervix bursae moderate, 

 broader than adjacent part of ductus; corpus bursae rotundate or 

 slightly ovate; signum stellate, scobinate.
