MiCROBRACON Ashmead ^'^ 



{Bracon auctt. not Jurine) 



As here considered this genus includes the species formerly placed in both Habro- 

 bracon and Microbracon. It is a large and very difficult group. Most of the species 

 are parasites of lepidopterous larvae, but some attack Coleoptera, while a few are 

 found parasitizing both lepidopterous and coleopterous larvae which occur in similar 

 situations.

 probably occurs throughout the State.

 (Ashm-CU) ; McLean, Aug 1 (Mues-CU_) ; Oswego. Undoubtedly throughout 

 the State; very widely distributed, occurring from Me. to Calif. Its recorded 

 hosts include Psorosina hammondi Rly. (Pyralidae), the oriental peach moth 

 {Laspeyresia molesta Busck), the grape leaf -roller (Desmia funcralis Hbn.) 

 (Pyralidae), the grape berry moth (Polychrosis viteana Clemens), the apple- 

 leaf-roller (Archips argyrospila Wlk.) (Tortricidae), and Gelechia spp.

 M. hebetor (Say). Bost. Journ. Nat. Hist, 1836, 1:252. Ithaca, Jl (Ashm-CU). 

 A very abundant cosmopolitan species, occurring throughout the range of its 

 hosts. Its principal hosts are the flour and meal moths, Ephestia kiihniella 

 Zell. and Plodia interpunctella Hbn. It also parasitizes other species of 

 Ephestia, the angoumois grain moth (Sitotroga cerealella Oliv.) (Gelechiidae),
