This tachinid ap- pears not to be un- common as a piarasite of the br o wn-t ail moth in Italy, but has not been received from other countries in more than the most insignificant num- bers. Not enough have been received to make anything like colo- nization possible, and it is one of the species which it is hoped to receive in 1911. Eudoromyia magnicornis Zett. This (see fig. 73) is the most distinc- tive of the tachinid flies parasitic upon the brown-tail moth, and the only one among the parasites of either the gipsy moth or the brown-tail moth which has the habit of depositing its active larvae upon the food-plant of its host. This habit was first discovered by Mr. Townsend, who gives an account of the manner of the discovery in Techni- cal Series VI, part 12, of this bureau, from which the accompanying figure (fig. 74) was taken. It is another of the group of tachinid parasites which appear to be southern rather than northern in distribution, on account of which it has been found impossible to secure a sufficient number to make adequate colonies.
