These tlies were present iii such numbers that their buz/ing, as they flew over the army of caterpillars, could be heard at some distance and the farmers were unnecessarily alarmed since they conceived the idea that the llies were the parents of the cater- pillars and were llying everywhere and laving their eggs in the grass and wheat. As a matier of fact, one great outbreak of the army-worm in northern Alai\ima. in the earlv summer of 1881, was c o m p I e t e 1 >• frustrated by the tachina llies, aided by a few other parasites and predatory insects.

Their eggs are white in color, oval in and are stuck by some sort of a gummy substance to the surface of t'c insect on which the tuture are to feed.
