 largest and most striking syrphid in the region. Taken at wild cherry 

 blossom, March 7. Hogtown Creek, May 21. 



Eristalis vinetorum Fab. Taken at the blossoms of various plants 

 but is uncommon. A specimen was taken at window light. May 26. 



The larvae of the genus Eristalis are of the long-tailed, filth-inhabiting 

 type of syrphidse, which live normally in sewage and putrid or stagnant 

 water, (Metcalf '16, p. 218). 



TACHINID^. 



Jurinea adjusta V. d. Wulp. Numbers of this very large hairy 

 tachinid were taken at Crategus blooms, March 25. Common at 

 chinquepin blooms. May 3. 



Spallanzania hebes Fall. A number of specimens were taken at 

 chinquepin blooms, May 23. 



Archytas lateral's Macq. This was the most abundant parasite 

 reared from Malacosoma americana. These large flies issued from 

 pupae April 13-14. 



Achaetoneura schizuras Towns. Numbers were reared from Mala- 

 cosoma americana larvae, April 13.

Sarcophaga ppifera Coq. This species was reared from one of the 

 bird grasshoppers, Schistocerca alutacea, October 28th. The per- 

 centage of parasitization is small, only one individual being parasitized, 

 this one producing seven adult flies, out of fifteen of the grasshoppers 

 collected in the field.
