SEKPHOID AND CHALCIDOID PARASITES OF THE HESSIAX FLY 147 



been verified by additional rearings. One of the identified species 

 belongs to a group, Alysiidae, which is outside the author's present 

 field of activity but will be mentioned here because of the proba- 

 bility that the record is correct and in order to make this list of 

 hessian-fly parasites as nearly complete as practicable. 



The alysiid Coelinklea meromiyzae Forbes is represented by one 

 specimen said to have been reared from Phytophaga destructor at 

 Wellington. Kans., by E. G. Kelly, under Webster no. 4087, Expt. 

 no. 152273, and another is said to have been reared from the same 

 host by the same collector at Watenga, Okla., under Webster 

 no. 17319, Expt. no. 152415. This species is a well-known parasite of 

 Meromyza mnericana Fitch, the wheat stem maggot. The fact that 

 this species normally attacks a dipteron infesting the stems of wheat. 

 even though it is a species belonging to an entirety different family 

 from that to which the hessian fly belongs, makes it appear reason- 

 able to believe that the records may be correct. Nevertheless, con- 

 sidering the great amount of rearing of hessian-fly parasites that 

 has been done and the abundance of Coelinidea meromyzae, it is 

 difficult to understand why it has not been reared by others from 

 this host.
