Described from specimens bred by Prof. F. M. Webster, 

 August, 1894, from eggs of Fidia viticida, on grape-vine. 



This species comes nearest to Tricho gramma acuminatum, 

 Ashm., Can. Ent, 1888, p. 107, which should probably be 

 referred to this genus, but differs decidedly in the color of 

 the legs and abdomen.
