Baird. Holland's figure under congermana appears to be this

640. M. pulverulenta Smith. — High River, June 16th, 1914 

 (Baird), one male. Banff (Sanson). Described from Mrs. Fern- 

 aid's collection as a grey variety of assimilis, the reference having 

 been decided by identity in the rather peculiar structure of male 

 genitalia in the two forms. These I have not so far examined, 

 but I feel quite convinced that the two forms are distinct species. 

 In assimilis the t. a. line is nearly straight in the sub-median 

 interspace. In pulverulenta it is rather deeply crenate. The 

 claviform in pulverulenta is both narrower and shorter, and, as a 

 rule, the orbicular and reniform are smaller. The white patch 

 near the anal angle is usually larger, and there is more white in 

 the s. t. line opposite the cell. A red-brown tinge to the entire 

 ground colour of primaries is not unusual. 



No locality is given with the description. In Hampson's 

 Catalogue pulverulenta is treated as "ab.l" of assimilis, under 

 which specific name only two specimens are listed, a male from 

 Vancouver Island, and a female from Buffalo, N. Y. (Massa- 

 chusetts in error). Both these specimens are pulverulenta, and 

 that from Vancouver Island is figured under assimilis. In Van- 

 couver I. specimens the grey overlay is usually very slight. The 

 most intensely black specimens which I have seen are a pair from 

 Tacoma, Washington. The assimilis of the Kootenai List is this 

 species. 



641. Barathra curialis Sm.— Edmonton. A male, rather 



rubbed, June 17th, 1910. (F. S. Carr.) 



[642. Xylomiges cognata Sm. — Barnes and McDunnough, in 

 Contr. II, No. 1, pi. vii, fig. 4, figure a male of this species from 

 Calgary. Its occurrence in Alberta is of course possible, but so 

 far I have no authentic record of any Xylomiges from east of the 

 Rockies in Canada besides dolosa, with the exception of tabiilatay 

 which is recorded from Montreal, and is apparently exclusively 

 eastern.]
