of forewing drab mixed with gray; forewing with indistinct pale longi- 

 tudinal streak from base to slightly below apex; dorsum and apex 

 shaded with fuscous; apical cUia whitish and confluent with pale 

 longitudinal streak, remainder light grayish fuscous. Hindwing 

 grayish fuscous, paler basally; cUia grayish with darker basal band. 

 Legs drab; tarsi with indistinct pale annulations. Abdomen grayish 

 fuscous, somewhat lighter beneath. 



Male genitalia (shde 10710): Harpe broad; costa with short, 

 flattened terminal process; cucullus sub triangular, outer edge strongly 

 curved; sacculus broad, heavily sclerotized and terminating lq a broad, 

 bluntly pointed, short process. Gnathos asymmetrical, twisted, more 

 than twice the length of uncus. Uncus almost as wide as long, apex 

 rounded. Aedeagus stout with apical, beaked process. 



Female genitalia (shde 10702): Ostium transverse, oval, periphery 

 strongly sclerotized; ventral hp of ostium about as broad as long and 

 posterior edge rounded. Ductus bm'sae membranous. Inception of 

 ductus seminalis slightly posterior to junction of ductus bursae and 

 bursa copulatrix. 



Type: Masatierra: Salsipuedes, 400 m. (Mar. 5, 1951). 



Described from the type male and one female paratype with same 

 data. A nondescript insect with scarcely any distinctive superficial 

 features. The longitudinal pale streak is ill defined (more clearly so 

 in the worn female) and best indicated by the whitish terminal spot. 

 The male genitalia suggest a close relationship to chiloma. In both 

 species the uncus is very short and the gnathos is asymmetrical and 

 distorted but glareola can be distinguished from chiloma by the presence 

 of a costal process on harpe, a broader, bluntly pointed sacculus, and 

 the beaked apex of the aedeagus. The females do not exhibit this 

 close relationship. The enormous ventral lip of the ostium of chiloma 

 and the strongly sclerotized posterior section of ductus bursae im- 

 mediately separate chiloma from glareola.

 Antenna and head blackish fuscous, the latter with some light scaling
