OCCURRENCE OF THE THROAT BOT IN CUBA.

Although the horse bot {Gastrophilvs equi Fab.) is commonly 

 known in Cuba, I can not find that rtasdlis has yet been rei)orted. I 

 had had specimens of tlie latter from Texas, Kansas, and A^Voming. 

 Now, it has been taken flying about the plow nudes here on the

This occurrence is esi)ecialy interesting, because with it may be 

 noted an apparent divergence in habit. Ordinarily it is said to annoy 

 animals by striking for the vicinity of the neck for the deposition of

 (litlercnce in the egg-laying habit remains to be determined.

A common Cuban fruit which occurs in gardens and patios is the 

 tree gooseberry, or grosella, a species of Phyllanthus. This tree is 

 commonly completely and rapidly defoliated by a most pernicious 

 pest — the larva of Melanchroia geometroides Walk. I had observed 

 this insect in passing as to its parasites, none of which appeared to 

 exercise the least check upon it. One day, in visiting a tree swarm- 

 ing witli the larva" and almost defoliated, I discovered tliat great 

 numbers of them were dead and dying, their blackened skins hanging
