pedicel. The parent insect probably deposits her eggs on the 

 skin of the grape, and the young larvae, as soon as hatched, 

 puncture the skin and work their way to the seed, which they

Eudemis hotrana (Schiff.).

 to its ravages. When abundant, it is very destructive ; in 

 some instances it is said to have destroyed nearly fifty per

The young larvae are found injuring the grapes early in
