FlG. 4. — Apanteles canarsiae, a parasite of the grape leaf-folder: a, Apanteles larva feeding on grape leaf- 
folder larva; b, adult Apanteles (natural size at right below); c, cocoon of same; d, pupa of same. 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 
abundantly scattered over the larval webs of Desmia during the latter 
part of August and the first of September. The minute, sluglike

crawls some distance from the remains of its host, and within an hour
