 Amolita delicata, sp. nov. 



^ . — Head, thorax and abdomen pale gray ; primaries very pale 

 ochreotis, suffused in the basal half and along costa with grayish, and 

 finely sprinkled with black scales ; faint traces of an oblique ochreous 

 dash from apex to end of cell, caused by a lack of black scaling at this 

 point ; two minute black points may or may not be present at end of cell, 

 close together; veins more or less marked with ochreous; fringes con- 

 colorous ; secondaries slightly smoky, with traces of a dark terminal line 

 and a smoky line cutting the white fringes. 



9 . — Very siniilar to the c^ ; the oblique apical dash better defined, 

 due to darker marg-inal shading on both sides ; frequently traces of a dark 

 shade in the cell ; veins light ochreous, giving a distinct strigate appear- 

 ance to outer area of wing ; secondaries pure white, with slight sprinkling 

 of dark scales along costa and outer margin ; fringes white with dark 

 basal line. Beneath primaries of $, smoky, secondaries whilish, sprinkled 

 with smoky especially along costa, and with faint discal dot; in Ç 

 primaries are much lighter than in $ and the discal dot of secondaries is 

 wanting. Expanse, ^, 25 mm.; 9, 29 mm. 



Habitat: White Mts., Ariz, 9 (? s, 7 $ s. Types, collection Barnes. 



Vein 8 of secondaries arises from about the middle of the cell and not 

 from the base as in Hampson's definition of the genus Amolita. As, how- 

 ever, this is also the case with roseola Sm., which is retained in the 

 genus, we place it here rather than in Doerriesa Staud., in which it would 

 fall according to Hampson's tables. The $ antennae are laminate. The 

 species varies somewhat as regards the black sprinkling, several specimens 

 being almost uniformly pale ochreous, whilst others are distinctly sprinkled, 

 with the veins showing clearly. 

 Amolita fratercula, sp. nov. 



Primaries : ground colour pale ochreous suffused with gray, and rather 

 evenly shaded with smoky brown ; the most prominent feature is an 

 oblique dash of the ground colour which extends from a point on outer 

 margin just below costa inwards to the cell and is shaded superiorly with 

 smoky brown, which shade extends more or less distinctly through the 

 cell to the base of wing, leaving the cubital vein as a fine ochreous line 

 distinct to the discocellular vein. In the $ two very faint dark dots are
