In the National Collection are two males from Aweme, Manitoba, 

 collected by N. Griddle ("II-VIII-1915," and «2-VIII-1915"), 

 which I recognize as this species. They answer very well to 

 Moschler's description and agree with the specimen from Labrador 

 in the Fernald collection. This latter bears Moschler's label and is 

 very likely the actual type. From transversa these specimens are 

 separable by the paler cilia of their hind wings and the peculiarly 

 marked cilia of the fore wings. In both elongana and transversa the 

 fore wing cilia are fuscous with a thin sub-basal white line and the 

 tips of the hairs white, while in tarandana the cilia are distinctly 

 white with a moderately broad median fuscous band. Veins 3 and 4 

 of hind wings are stalked.

32. TfflODIA CINEREOLINEANA, new species. 



(Fig. 132.) 



Dark grayish fuscous, the ends of many scales tipped with white. 

 Fore wing with vein 2 straight; termen slanting and concave; 

 veins 3, 4, and 5 somewhat approximate at termen ; costa strigulated 

 with fine blackish fuscous and white geminations ; along the fold and 

 on several of the veins longitudinal streaks of blackish fuscous scal- 

 ing, between which the dark scales are more evenly tipped with white, 

 giving the fore wing the appearance of being finely streaked longi- 

 tudinally with ashy white and dark gray ; ocelloid patch white with 

 two longitudinal black streaks; cilia white with a fine subbasal and 

 a somewhat broader subterminal fuscous line. Hind wing with 

 veins 3 and 4 united; pale smoky fuscous, darkening toward apex 

 and along termen ; cilia whitish with a fuscous basal line.
