The genus Trichodezia, Warren, established in 1895 (Nov. Zool. II, Part 2, page 119), will now contain two of our species. In a former paper (Can. Ent., Vol. 38, p. 38) I stated that Euchœca albovittata, Guen., should, as Mr. Warren placed it, be recognized as the type of this genus, and ventured to predict that Euchœca Californiata, Pack., would go with it. Since then, through the kindness of Mr. Beütenmuller, of the Amer. Museum of Nat. History, N.Y., I have received a male of this species, and find the peculiar generic characters present.
