Braconidae 



Bracon xanthonotus Ashmead was reared from only a single collec- 

 tion of Malacosoma californicum (Packard). This was Coll. No. 446 

 (Grand Canyon Nat. Park, Ariz.). 



Rogas sp. (or spp.) was the most common of all the larval para- 

 sites reared from Malacosoma in this study. It was reared from 51 

 different collections of M. californicum and its subspecies, and from 

 one collection of M. incurvum irwurvum in which all of the Rogas were 

 hyperparasitized. It is not presently known whether more than one 

 species of Rogas is involved, but many of the specimens are undoubtedly 

 the same species as the one Langston (1957) called Rogas sp. All of 

 the collections in the following list are records for Rogas sp. (or spp.).
