Much enlarged. (Original.) The following notes were made on the life histories of several of the foregoing species during the course of the study. Several individuals of Apanteles canarsiae Ashm. (fig. 4) were found in considerable numbers. Their small white cocoons were quite abmidantly scattered over the larval webs of Desmia during the latter part of August and the fu-st of September. The minute, sluglike larvae of the parasite feed externally, a single individual completely consuming the soft parts of its host. When fully grown the larva crawls some distance from the remains of its host, and within an hour.
