Enlarged. (Original.) cated fairly well in the accompanying illustration (fig. 60), which represents a" pocket" of parasitized caterpillars torn open. Very little of interest is associated with the life and feeding habits of these larvae. The female pierces the host caterpillar with her ovipositor preliminary to the deposition of her egg externally, and the caterpillar thus stung is fre- quently rendered quiescent, and may even die before the hatching of the para- site larvae. The hibernating larva of Apanteles is so small as to be very difficult of detec- tion until after it has resumed activity in the spring and increased in size. Its exact appearance during the hibernating stage can not be de- scribed, because nearly every specimen found has been injured more or less in the removal. The accompanying illustration (fig. 61) is from a sketch made by Mr. Timberlake of a half-grown larva from life. None of the preserved specimens shows the curious projection beneath the anal bladderlike appendage which latter is characteristic of the early stage larvae of the subfamily to which Apanteles belongs. The head and mouthparts are strikingly dis- Fig. 61.—Apanteles lacteicolor: Imma ture larva from hibernating caterpillar of the brown-tail moth. Much en- larged. (Original.).
