We have much pleasure in naming this species after Mr. G. 

 Chagnon, of Montreal, from whom we received the type speci- 

 mens. The species bears considerable superficial resemblance to 

 Xylomoia diionea Sm. from Colorado, but lacks among other 

 things the distinct white-marked t. p. line as well as showing a 

 well-defined post-median line on secondaries; the front is rather 

 improminent, being slightly less bulging than in didonea but the 

 species resembles so markedly the figure of the generic type, 

 Xylomoia graminea Staud., figured in Rom.- Mem. VI, PI. 12, 

 fig. 8, that w^e incline to place it in -this genus. We have single 

 worn specimens of this new species from Cartwright, Man., and 

 Durango, Colo., which would indicate an extended distribution.
