wing middle, connected with a concolorous flat costal triangle reaching 

 to wing apex, and a rather broad terminal line. Most of supradorsal 

 area below discal cell darkened with brown. Some concolorous dots 

 in discal cell and other parts of wing. Small inconstant gi-oups of 

 black raised scales around discal cell. Cilia concolorous with head 

 or somewhat paler. Length of forewing, 9-10 mm. Hind wings 

 pale smoky. 



Male genitalia. — Unknown. 



Female genitalia. — Sterigma with long broad lateral lobes ro tun- 

 date at tips and slightly bent inward apicall3^ Ostium bursae broad, 

 sinuate. Antrum a broad sclerotized tube, slightly longer than lateral 

 lobes of sterigma, dilated caiidad, excavate cephalad; angles of antrum 

 laterad from ostium bursae bent cephalad and rather long. Bm-sa 

 copulatrix with a broad cervix sclerotized caudad; its corpus ovate. 

 Signum elongate, scobinate, narrowed caudad. 



Types. — Holotype, female (genitalia on slide 2-Obr., Feb. 16, 1959), 

 Bendon, Oreg., Sept. 24, 1956 (J. Capizzi); allotype, male, and two 

 female para types, taken together with holotype. All the above types 

 in USNM (no. 65588). 



Food plant. — All fom* examined specimens were reared from 

 strawberry. 



Remarks. — The abdomen of the single male specimen was received 

 preprepared, glued to a piece of paper, with the genitalia missing. Ex- 

 ternally this male is somewhat similar to Acleris Upsiana (Schiffer- 

 miller and Denis), but has obhterate markings of forewings that are 

 lacking in the latter species. The females might remind one some- 

 what of Acleris maccana (Treitschke) aberration leporinana Zetter- 

 stedt (Kennel, 1908, pi. 4, fig. 20), although they do not match its 

 markings exactly. The female genitalia of the new species are similar 

 to those of Upsiana, but the antrum is shorter and broader, and the 

 ductus seminalis is joined to the ductus bursae remote from the 

 antrum; in Upsiana the ductus seminalis opens directly cephalad from 

 the antrum. The new species is named for its collector.

Male. — Unknown. 



Female. — Head dark brownish gray with scales white edged. 

 Labial palpi concolorous with head, their inner side whitish. Thorax
