SEKPHOID AND CHALCIDOID PAEASITES OF THE HESSIAN FLY 85 



Sacramento nos. 19938 and 19939. mentioned in the enumeration of paratypes. 

 The female parent of this series has normal eyes. The male parent has un- 

 mistakably large eyes. The progeny of this pair consist of 5 females and 7 

 males; and in all the progeny, both male and female, the eyes are normal. 

 Unfertilized females of the species normally produce only males, and it is quite 

 certain, therefore, that this female was fertilized. The notes on this experi- 

 ment by M. C. Lane show that the mating of this pair took place under his 

 observation and that the female deposited 45 eggs, of which 13 developed into 

 adults.
