391. Polychrisia trabea Smith. — During 1910 I took this 

 species in some numbers at flowers of wild larkspur, on which the 

 larva in all probability feeds. 



392. P. piirpurigera Walk. — Edmonton, July 14th, 1910 

 (F. G. Carr.) 



395. Euchalcia putnami Grote. — The type is a female in the 

 British Museum. There I found North American and European 

 specimens associated as one species under the name festiicce Linn, 

 and my notes say that the reference is apparently justified, as the 

 European species varies to putnami. As a rule, the European form 

 is darker and richer in colour and has a golden metallic spot at the 

 base of the costa which putnami generally lacks. Another char- 

 acter not usually found in putnami is a metallic outer edging to 

 the t.a. line below the median vein. In putnami the two central 

 metallic spots are sometimes joined. I am not sure whether this 

 is ever the case with festucce. At any rate, such variation is rare 

 in Europe. Vancouver Island specimens vary very much nearer 

 to typical festucce than do my local series. Some have the rich 

 dark coloration, the metallic marks at base, and on the t.a. line; 

 but the inner one of the two central spots less frequently extends 

 a little above the median vein than it does in Alberta specimens, 

 or than appears to be the case in festucce. 



398. Autographa calif ornica Speyer. — The most important dis- 

 tinctive mark between this species and pseudogamma I had over- 

 looked in my previous paper. Calif ornica has a fine black longitudi- 

 nal streak anterior to the subterininal line near the apex, which usual- 

 ly reaches, or very nearly reaches, the t.p. line. In pseudogamma 

 this streak is non-existent. It exists in on, which resembles cali- 

 fornica rather closely in pattern, though unquestionably distinct. 

 As ou has quite recently been added to the Canadian list, on the 

 strength of a specimen taken at Aweme by Mr. Griddle, a com- 

 parison with californica may be of special interest. In californica 

 the t.p. line is somewhat deeply sinuate near the inner margin. If 

 viewed with the outer margin of the wing upwards, that portion 

 of the line below vein 2 has the shape of a written "n" with the top 

 of the first stroke rather pointed. In ou this portion of the line 

 is very slightly waved only. In californica the sign is usually
