Host. — Mayetiola destructor Say. 



The type material consists of five females and thirty-five males, all 

 either reared or bred from Hessian ^y puparia, by Messrs. W. R. 

 McConnell and P. R. Myers. The type and allotype were reared 

 from puparia collected at Hanover, Pennsylvania. Seven of the 

 male paratypes are progeny of the type female and bear Cage No. 

 972, Female paratype A, also from Hanover, is the parent of four- 

 teen male paratypes bearing Cage No. 987, and one bearing Cage
