fuscous dusted with white. Fore wing white lined and marked with 

 blackish fuscous ; a dark, outwardly angulate basal patch, its blackish

 patch ; just above this at lower outer angle of cell a small elongate 

 brownish fuscous patch edged with blackish scales; several narrow 

 blackish fuscous streaks on costa, those towards apex more conspicu- 

 ous than the others and continued towards termen in thin brown lines ; 

 a rather conspicuous, inwardly pointed, short blackish apical dash; 

 ocelloid patch nearly obsolete, determined by two semi-metallic 

 silvery bars; margining ocelloid patch on outer and upper sides a 

 curved line of black scales; whitish areas otherwise rather finely 

 streaked and dusted with blackish fuscous scales giving the insect a

 and 2 female paratypes from Provo, Utah (Spalding, Aug. 10-11,

Clemens erected his genus Catastega for three species {timidella., 

 aceriella., hamumsliella) which he knew and described only as 

 larvae ; establishing the genus on the larval habit and separating the 

 species on the differences in food plant.
