THE CANADIAN ENTOMOLOGIST 19 



Paratypes. — 3 cfs and 2 9s from Victoria and Duncans, 

 B. C, in my collection; 4 d^s, 7 9 s, June 7 to July 3, from Vic- 

 toria and Coldstream, B.C., in the collection of Mr. Blackmore. 

 One d^ Salem, Oregon, June 2, 1904, with other &s and 9 s 

 from British Columbia in the Barnes' collection. , 



- Xanthorhoe macdunnoiighi can be easily separated from 

 pontiaria Taylor by the general gray colour of the primaries, the 

 gray head (that of the latter being reddish) and the narrower pec- 

 tinated antennae. 



Xanthorhoe forsaria Taylor (Can. Ent., 1. c, p. 401) has been 

 a puzzle for a long time. It is evidently a species of high altitudes, 

 as I have never seen any except from mountainous regions. The 

 specimen from Laggan, Alberta, July 20, 1904, may not be the 

 same dis forsaria, as I have a 9 from the same district which seems 

 distinct. The type specimen taken in August is a yellowish ashen 

 with a faint, reddish brown median band, the whole insect having 

 a rubbed appearance. I have seen two other specimens taken 

 on Mt. Cheam, B.C., by Mr. Bush through Mr. E. H. Blackmore, 

 and they agree with Drs. Barnes' and McDunnough's specimens. 

 The central band is narrow at the inner margin, and has the pro- 

 jections of the extradiscal line well rounded off. I have a form 

 approaching /or^aria Taylor very closely from Atlin, B.C., which 

 I propose to describe as follows: 



Xanthorhoe atlinensis, sp. nov. 



Head, thorax and abdomen fuscous; antennae rather narrow 

 as in macdunnoughi. Primaries smoky fuscous, rather diaphanous, 

 crossed by seven or eight scolloped fuscous lines, with a faint, 

 reddish brown median band. There is a basal brown patch, the 

 outer edge of which runs out from costa toward median vein, then 

 bends backward and goes to inner margin. There are three 

 brown scolloped hair-lines between basal and intradiscal lines. 

 The intradiscal line curves slightly outward till just below costa, . 

 then runs straight to inner margin, with a slight curve, being 

 accentuated on the veins. There is a second hair-line running ex- 

 actly like the intradiscal and almost touching it. The centre of 

 the median band is lighter than the sides, and has a small, black 

 spot. There is a hair-line just before the extradiscal which makes
