Originally described from a single male specimen, this species has 

 become known as being widel}^ distributed in Central ChUe. It is 

 rather variable, having the forewings ocherous, golden ocherous, 

 testaceous, or hessian brown with a more or less intensive, ferruginous- 

 ocherous reticulation and/or incomplete, oblique rows of blackish 

 or grayish dots in the apical wing portion and occasionally basad from 

 it. The upper basal angle of the forewing generally stands out as a 

 triangle of a different color from the remaining wing surface and is 

 gray or whitish, concolorous with the thorax. On the dorsum, slightly 

 before tornus, there is a large, more or less distinct, white to grayish- 

 yellow or brownish-yellow triangular spot rather broadly outlined by 

 brown and checked by short, gray, or brownish streaks along the 

 dorsum. A slight, ferruginous-ocherous line sometimes connects the 

 apex of this triangle with the middle of costa. The length of the fore- 

 wing is from 10 to 13 mm. Hindwing whitish yellow to ocherous, 

 becoming gray basad in most specimens. The head is generally 

 concolorous with the thorax. 



Male genitalia: Uncus moderately long; socii long, equally broad. 

 Fultura superior rather broad; fultura inferior high. Valva with apex 

 directed upward; sacculus broad, sharp pointed at tip, protruding 

 valva. Aedeagus moderately thickened; two or three long, variously 

 thick cornuti; a minute, sclerotized plate in external portion of vesica. 



Female genitalia: Lamella antevaginahs bracket shaped, with lateral 

 portions directed caudad and bearing angulate prominences toward 

 ostium bursae. Antrum large, semirotundate. Corpus bursae pyri- 

 form, densely scobinate; signum located close to its middle, rather 

 small, situated on a swollen base; cervix bursae rather broad.
