SEEPHOID AND CHALCIDOID PAEASITES OF THE HESSIAN FLY 41 



sites of Harmolitm hordei (Harris). The types of Decatoma amster- 

 damenms bear the same note number (Webster no. 9355) and other 

 data as do the types of Harmolita atlamtica Phillips and Emery and 

 were undoubtedly reared in conjunction with that jointworm from 

 stems of Ag^ropyron. There is no reason to doubt that they were 

 parasites of H. atkbntica. 



A single specimen of D. amsterdamensis was reared March 16, 1919, 

 from an isolated puparium of Phytophmga destructor collected by 

 W. R. McConnell and C. R. Crosby on the university farm at Ithaca, 

 N.Y. 



Nothing is known of the life history of the species. 



DISTRIBUTION \ 



Up to the present time the species is not known to have been taken 

 except in New York State. The source of the three specimens men- 

 tioned by Balduf as having parasitized Harmxolita hordei, however, 

 is unknown. In New York State it is said to have been taken in 

 Fenn Yan, Auburn, Geneva, and Ithaca. 



IMPORTANCE 



Since but one specimen has been reared from the hessian fly, the 

 species is evidently of no importance as a parasite of that pest.
