rated. There are also other obvious differences in the shapes of 

 their harpes and aedoeagi. These are clearly indicated in our 

 figures. 



32. EPINOTIA DIGITANA. new gpecies. 



(Fig. 382.) 



Very like and close to nigralhana Walsingham and transmissana 

 Walker. Distinguished from the latter by having a complete anti- 

 median white fascia bordering the brown basal patch on fore wing; 

 this fascia has an indistinct thin median fuscous line but no suf- 

 fusion of brownish or metallic scaling obscuring the white toward 

 costa as in transmissaim. From nigralbana it differs in having a 

 short white spur projecting out from the middle of the outer margin 

 of the white fascia into the dark postmedian area. In nigralhana 

 there is a spur at the same place on the wing, but it is an inward 

 projection from the i)ost median brown area (or fascia) into the 

 white antimedian fascia. From all other American species of Epin- 

 otia, digitanu differs in having a slender, prominent poUex or finger- 

 like process projecting from the anal angle of the cucuUus of the 

 harpe.

Type.— C2it. No. 24846, U.S.N.M. 



Type locality. — Kaslo, British Columbia. 



Food plant. — Unknown. 



Described from male type from Kaslo, British Columbia (H. G. 

 Dyar, " 23588 ") and 1 male paratype from Pullman, Washington 

 (C. V. Piper). Both are from the National collection and had been 

 determined as transmissana Walker. The paratype had been so 

 labeled by Kearfott.

An eastern and north eastern species closely resembling the west- 

 ern alhangulana Walsingham, but distinguished by its much stouter 

 genitalia and the evenly angulate basal patch on fore wing, that of 

 alhangulana having a notch on outer margin below middle which is 

 lacking in transmissana. The latter is also a much more uniform
