Hagen notices (Proc. Bost. Soc. N. 11. xi. p. 434) the occurrence in the 
stem of the cotton-plant of the eggs of a grasshopper, probably allied to the 
Katy-did. Scudder remarks (1. c. p. 435) that he had received similar 
twigs with the insect said to oviposit in them, which is a species of 
Xyphidium, and added that Conocephalus ensiger had been seen with its ovi- 
positor forced down between the root-leaves and stalk of a species of Andro- 
poyon,

Scudder records his having obtained numerous specimens of a Chalci- 
dite from a cluster of eggs of (Edipoda Carolina (Proc. Bost. Soc. Nat. Hist,
