PARASITES OF GTPSY-MOTH PUP^. 249 The egg which is figured (fig. 52) was dissected from a female which was imported in 1909 with cocoon masses of the brown-tail moth and which was evidently hibernated. She was given no opportunity to oviposit. In 1910 several females were collected in the open in June, and these, upon being supplied with fresh pupae of the brown-tail moth, immediately oviposited.

PARASITES OF GTPSY-MOTH PUP^. 249 The egg which is figured (fig. 52) was dissected from a female which was imported in 1909 with cocoon masses of the brown-tail moth and which was evidently hibernated. She was given no opportunity to oviposit. In 1910 several females were collected in the open in June, and these, upon being supplied with fresh pupae of the brown-tail moth, immediately oviposited. The very characteristic larvae (fig. 53) feed externally upon the pupae of tachinids within the puparium, but internally within the pupae of Lepidoptera. The pupae (figs. 54, 55) are also characteristic, and the appearance of that of the female is indicated by the accompanying illustrations. The exit hole (fig. 56) left in the gipsy-moth pupae is invariably smaller than that left by Chalcis, and larger than that of Diglochis. It may be located anywhere, in which respect it differs from any of the larger of the pupal parasites. As a secondary parasite, Monodontomerus has been reared from tachinid puparia upon numerous occasions both from those which have been received from abroad and from those collected in America. It was rather expected of it that its attack would be confined to those Fig. 52.— Monodontomerus xreus: Egg. Greatly en- larged. (Original.).
