Biological Noles on Reared Parasitic Hymenoptera. 39 



Bracon PUNGiCOtA Ashmead. Types reared by myself 

 from Black Knot, Pl&wrightia morbosa Schw., and collected in 

 Wayne County, Ohio. For description see beyond. 



Ph.enocarpa fungicola Ashmead. Types reared with 

 the preceding species. Described also by Mr. Ashmead in 

 his paper. 



Glypta vulgaris Cresson. Reared with the preceding. 

 Described in Trans. Am. Ent. Soc. Vol. Ill, p. 154, the habitat 

 being there given as Eastern and Middle States, but now 

 known to have a much wider range. 



In regard to the respective hosts of the three species last 

 mentioned, it is impossible to give exact information. The 

 other inhabitants of the fungus, from which they emerged, 

 were as follows: Two undetermined species of Diptera, a 

 Cecidomyid and a Muscid ; Sccia pictipes G. & R. ; huzophera 

 sernifuneralis Walk; Tortrix sp? and Hydnocera verticalis 

 Say. Besides, the larvae of Conoti achelus nenuphar Hbst., 

 has been known to inhabit this furgus, though in this case 

 there was no evidence of their occurrence. 



Pygostolus americanus Ashmead. The types were 

 reared with the Labeo and Acoloides previously mentioned. 

 This wheat stubble was badly infested with Hessian fly. yet 

 the date of the emerging of this species, Nov. 26, renders it 

 doubtful if this is the true host. Described in Mr. Ashmead's 

 paper. 



Bracon rhyssemati Ashmead. The types were reared 

 at Wooster, Ohio from the larvae of Rhyssematus lineaticollis 

 Say, working in the seed pods of Asclepias incarnata L. The 

 same parasite was reared from the same host species at 

 Lafayette, Indiana, and infesting the same species of Ascle- 

 pias. See Proc. Ind. Acad. Sci., 1892, p. 89. Described in 

 Mr. Ashmead's paper. Also, probably occurs in New England. 



Merisus subapterus Riley. This was described in 1885, 

 from types reared in Missouri, from the Hessian fly. My own 

 specimens were reared from wheat stubble, also infested with 

 Hessian fly, at LaPorte, Indiana. Described in Proc. U. S. 

 Xat. Mus., 1885, p. 416, PI. XXIII, Fig. 2.
