INSECTS. 349 



Diptera. — ^Dr. Fitch describes as a new species Malo- 

 hrus mali. He found them in a fruit that had been per- 

 forated by the Codling-moth. The larvae are transparent ; 

 the flies resemble the Hessian-fly, that destroys the wheat 

 plant.* 



Cecidomyia grossnlarise, or Gooseberry Midge, attacks 

 the fi-uit, giving it the appearance of ripening premature- 

 ly. Considerable fruit is lost in this way.** 



In closing this chapter, the author feels obliged to ex- 

 press his regrets that no more space could have been ap- 

 propriated to this important subject. He eould only in- 

 dicate some of the most troublesome insects of our orch- 

 ards and vineyards, and he hopes that the reader will be 

 induced to pursue the investigation for himself. He 

 knows, by experience, that the study will bring its own 

 reward in the information that is received, and which is 

 absolutely necessary to enable us to combat these trouble- 

 some pests successfully.
