quite a sharp projection below costa, then curves back and runs 

 straight to inner margin. The extradiscal line goes straight across 

 costa, the forms the usual sinus, the projections of which are rather 

 more rounded than usual. Below the second projection the extra- 

 discal line runs back, then goes straight to the inner margin, being 

 rather narrow there. The median band has a reddish brown, 

 somewhat washed-out appearance, as in forsaria, and is narrow 

 at the inner margin. Beyond the extradiscal line is the usual 

 pale band, with two scolloped hair-lines; and a fuscous outer margin, 

 with subterminal, scolloped, white line. The fringe is short and 

 fuscous, with the small, marginal dots rather contiguous. Secon- 

 daries pale smoky fuscous with six or seven indeterminate scolloped 

 hair-lines, accentuated as dots on the veins. The extradiscal line 

 runs straight out from costa, making a rounded angle below the 

 small, black, discal joint. There is a pale band which is crossed 

 by a scolloped line, then a heavy scolloped submarginal line, fol- 

 lowed by a fuscous marginal border with the usual subterminal, 

 scolloped, white hair-line. 



Beneath the primaries are as above with the lines faintly 

 showing through, but the basal portion is darker than the outer 

 portion. Secondaries as above, but are darker basally. 



This species is closer to forsaria Taylor than any other, but 

 differs in the smoky diaphanous colour where the former has a 

 yellow or ochreous tinge. It also differs in the time of appearance. 

 These species all have the lines and bands running about the 

 same, and it is very difficult to draw any one character as con- 

 stant.

Paratypes. — One cf, June 28, 1914, from Mr. Blackmore, in 

 my collection, and 6 cf 's, June 28, 1914, in coll. Blackmore and 

 the Provincial Museum, Victoria, B.C. There is still another 

 species occurring in the vicinity of Victoria, B.C., which emerges 

 early in the season and resembles superficially pontiaria but is 

 more fuscous, and the central band is solid blackish with a tendency 

 to fade below median vein, as in forsaria and atlinensis. This 

 species was taken along with the others by Mr. Blackmore, and
