Var. {"à) p erf r act a Svvett (Can. Ent.. XLII, p. 279, igio). 



This looks like the norrrnl autunmalis, only the mesial space is 

 suffused with a deep i)ink and the course of the basal line is different. 

 This variety was referred to without name by Gueree) Phal, Vol. 2, 

 p. 39S, 1505, 1857) under pluvlata. It apprjaches superficially H. 

 califoriiiata, but I have pointed out the differences in the description. 

 The variety seems to be very rare. It was taken in the Catskills by Mr. 

 R. F. Pearsall There are no other records of it to my knowledge. 



Var. (b) ^;'(7/î:fr/ Swett (Can. Ent., XITI, p. 278, 1910). 



This variety occurs in the Northwest, most commonly around Victoria- 

 The green shadings of the typical form are replaced by yellow in the 

 variety, and it has an intensely black median irregular band, instead of 

 being of the usual slate colour. It is a very striking and distinct form ; 

 there is nothing approaching it among the European varieties. 



Var. (c) columbiata Taylor (Can. Ent., XXXVIII, p. 399, 1906). 



I have a photograph of the type, kindly sent me by the Rev. G. W. 

 Taylor for comparison, and it approaches the European var. cotistricta 

 Strand very closely, but it lacks the cinereous ground colour, and I think 

 it will remain in good standing. It may be known by the narrow mesial 

 area, shaded with dark where the typical form species is white. 'Fhe 

 intradiscal band near the inner margin lacks the long-toothed projection 

 of crokeri, and the hind wings are light ash with two bands beyond the 

 discal spot. It is also distinguished by the larger size and greenish 

 ground colour. 



Var. (d) constricta Strand (Ent. Zeit., Gub. XIV, p. 61, 1906) also 

 Berl. Ent. Zeit., Vol. 51, p. 254-257, 1906, and Ach. Naturv. Christiania, 

 XXII, No. 5). 



This is a peculiar cinereous form, in which the mesial white space is 

 suffused with smutty striations, giving the whole a rather smoky appear- 

 ance, approaching melanism. The blue irregular median band is very 

 faint and the lines are all hardly discernible. The variety can best be 

 separated by the dark narrow central space and dark hind wings with 

 prominent discal spots and two extradis:al bands. I have examples from 

 Norway, Germany and North America, the latter being represented by a 

 J and a ^ from Forest Hills, Mass. (June 20, 19 11), and Monmouth, 

 Maine (June 25, 1903), which agree with the European specimens. I have
