SOME MOTHS, GENUS ACLERIS — OBRAZTSOV 255 



yellowish raised scales forming distinct patches: one in basal part of 

 discal cell, and three in its distal part. Some less distinct groups of 

 raised scales on costal patch and below discal cell, some above dorsum. 

 Cilia gi'ay with tips of scales paler. Reverse of forewings brownish 

 gi-ay with some obliterate yellowish patches along costa. Length of 

 fore wing, 10.5 mm. Hind wings pale grayish white. 



Female genitalia. — Sterigma with long, rather thin, almost 

 vertical lateral lobes. Antrum sclerotized, elongate rectangular, 

 dilated caudad, with caudal edge crescent, pointing cephalad. Mem- 

 branous portion of ductus bursae long, broad, equally wide along 

 its entire length. Signum stellate, scobinate. 



Type.— Holotype, female (genitalia on slide 2-Obr., Dec. 31, 1958), 

 Moscow Mountains, Idaho, Aug. 7, 1933 (J. F. Gates Clarke). In 

 USNM (no. 65589). 



Food plant. — Alnus species (corresponding to the data on label). 



Remarks. — Externally this species could easily have been taken 

 for some dark unicolorous specimen of Acleris hastiana (Linne), but 

 in the female genitalia it entirely differs from that species, and re- 

 sembles rather A. lipsiana (Schiffermiller and Denis) and A. apiciana 

 (Hiibner). The antrum of incognita is much shorter than in the two 

 latter species, and the lateral lobes of the sterigma are much narrower 

 and are distinctly pointed.
