oblique in opposite direction, the two spots forming a kind of triangle. 

 From this connection, a rather broad brownish-ochreous fascia 

 originates which reaches dorsum before tornus and is paler than the 

 costal spots. Margins of both costal spots and fascia finely outlined 

 by darker lines with small groups of brownish-black scales on them. 

 A fine short brownish line at costa before wing apex, oblique basad. 

 Two fine brownish-ochreous transverse lines between middle fascia 

 and termen, hardly separable from lines of ground reticulation. 

 Terminal line brown. Cilia ochi-eous. Reverse of forewings whitish 

 ochreous; costa with traces of markings of upper surface, and fine 

 short grayish lines; apex outlined by a brown terminal line. Length 

 of forewing, 7-7.5 mm. Hind wings silky white, slightly yellowish at 

 apex and cilia; in female with slight brownish-gray reticulation before 

 apex and termen. 



Male genitalia. — Similar to those of cervinana, but with aedoeagus 

 somewhat thicker and its preapical thorn strongly ciu"ved caudad; 

 three cornuti, more stout than in cervinana. 



Female genitalia. — Sterigma with lateral lobes broad and stout. 

 Antrum well developed, subcylindiical, slightly narrowed caudad. 

 Ductus bursae slightly sclerotized laterocaudad, then narrowed before 

 a wide sack forming its cephalic portion. Signum stellate, scobinate. 



Types. — Holotype, male (genitalia on slide, prepared by A. Busck, 

 Feb. 10, 1933), Santa Cruz, Calif., Oct. 29, 1932 (Tilden); allotype, 

 female (genitalia on slide 1-Obr., Jan. 28, 1959), taken together with 

 holotype. Types in USNM (no. 65586). 



Remarks. — Externally this species may remind one of Acleris 

 rhomhana (Schiffermdler and Denis), but it has a different wing shape 

 and completely dissimilar genitalia. Those of the male of the new 

 species are very close to the genitalia of A. cervinana (Fernald), but 

 differ as mentioned above. In the female, the lateral lobes of the 

 sterigma are broader than in cervinana; the antrum does not form 

 any curvation of caudal angles; the sack of the ductus bursae is not 

 narrowed caudad. From^. subnivana (Walker), which the new spe- 

 cies resembles in having a sinuate costa of the forewings but no like- 

 ness in their markings, it differs by much longer cornuti and entirely 

 distinct shapes of the sterigma and antrum,
