76 THE CANADIAN ENTOMOLOGIST 



scalloped and the fringe is rather long. Beneath the fore wings are 

 smoky black with discal spot showing through; the apices of the 

 wings are tipped with white. Hind wings of the same colour as fore 

 wings with black discal spot instead of ring as above. 



Type 1 cf, Cincinnati, Ohio; through the kindness of Miss 

 A. F. Braun. 



This is no doubt a case of melanism and was so identified for 

 me by Mr. Grossbeck. Melanism seems to be rare in this country 

 but is common in Europe where it seems to represent a more 

 recent type. 



Afiia limharia var. chagnoni, n. var. 



Expanse 22 mm.; palpi very short. Fore wings bluish yellow 

 with chocolate border, basal space and mesial space of the same 

 colour up to the chocolate-coloured margin. The basal line about 

 4 mm. out from body runs at right angles from costa to median 

 vein, then almost straight to inner margin. There are traces of 

 a large lunule near where the discal spot would be and expanding 

 to the extra-discal line. Beyond the extra-discal line the entire 

 margin is chocolate-coloured. Hind wings bluish yellow to the extra- 

 discal line, beyond the margin chocolate as in fore wings. There 

 is a large lunule in the discal space. Fore wings of the same colour 

 as above, the chocolate margin showing through. The hind wings 

 are the same as above, bluish yellow with a chocolate margin. 

 This seeems to be a case of melanism but the markings are not 

 identical with limharia. Possibly this is a northern species. It is 

 so different in appearance from limharia that one would hardly 

 recognize it, or where it belonged, were it not for the peculiar spur 

 of the hind tibiae. 



Type 1 cf , St. Therese Isle, St. Johns Co., Que., VII.-9-1912; 

 through the kindness of Mr. G. Chagnon, after whom I take pleas- 

 ure in naming this unique variety.
