Diagnosis. — The species is rather similar to opacella in most re- 

 spects, but is easily distinguished by the white trace on forewing vein 



Description. — Frons conical, scales solid light brown; labial palpi 

 with basal segments white, second segments reddish brown on outer 

 sides, third segments brown on outer sides, both white on inner sides; 

 maxillaiy palpi moderately small, not approaching frons; antennae 

 light brown, male laminate; occiput behind eye, patagia, and tegulae 

 light brown, vertex behind antennae bro^vnish white; legs white, 

 tarsi light brown. 



Forewings reddish orange anterior to cell; ground terra cotta; 

 costa and all other veins traced with white, trace of A2 bordered with 

 dark bro\vn, cubitus bordered posteriorly with dark brown line. 

 Hindwings light brown, darker toward apex. Venation as in tetradella. 



Male genitalia with gnathos bearing apical digitate projection. 

 Juxta V-shaped. Valvae with costa sparsely setose, bearing poorly de- 

 veloped apical tooth; sacculus with numerous fine hairs. Aedeagus 

 with vesica bearing a single serrate cornutus. 



Female unknown.

Discussion. — This form has its closest affinities to opacella, and 

 differs mainly in size and in that the valvae are rounded and lack the
