According to Knight's figure in the Kearfott Collection at the 

 American Museum this species is the eastern equivalent of major 

 Walsingham. In the collections specimens of cespitana, urticana, 

 and deprecatoria have been indiscriminately referred to it. I was 

 inclined to apply the name to the large northern and western form 

 of cespitana Hiibner {instrutana Clemens) ; but according to August 

 Busck, who examined the type, puncticostana lacks the dark shading 

 on the pale terminal area of fore wing which is present in all speci- 

 mens of cespitana. 



We have in the National Collection two males from New York and 

 Quebec received through Dr. W. T. M. Forbes. These agree in geni- 

 talia with major Walsingham. In the Canadian National Collec- 

 tion there are several small specimens (15-17 mm.) from New York, 

 and a series of larger (17-20 mm.) specimens from Ontario and Cen- 

 tral Alberta (Edmonton). There is also a male in the Barnes Col- 

 lection from Mount Washington, N. H. ("July 24r-31, 4,000 ft."). 

 Packards' murina is a straight synonym. The type at Cambridge 

 agrees in both pattern and genitalia with what we have under the 

 Walker name.

 sity collection from North Twin Brooks, N. Y. (W. T. M. Forbes,
