Work of Larv/e of Melon Fly in Blooms of Pumpkin. 



In figures 1 and 2 is shown the work of the larvae of the melon fly in bringing about the destruction 

 of the ovaries of pumpkin bloom even before the corolla has entirely withered. Note that in 

 figure 1 the corolla has not yet unfolded nor has the stigma been exposed. In figure 2 is shown 

 the more complete destruction of the ovary of a flower, the corolla of which has but recently 

 withered. (Original.)
