Type.—^o. 4969, U.S.N.M. 



Food plant two species of Eugenia. The mine is one of the most 

 interesting I have met with. Egg is laid on the underside of the leaf 

 and mine begins as a long narrow line along the edge of the leaf for 

 about 25 mm. and then turning inward it suddenly broadens out in a 

 large bladder-like blotch nearly covering the entire leaf. The upper 

 and lower epidermis are separated and the leaf is inflated and yields 

 to pressure like an air cushion, being from 3 to 6 mm. thick. Mine 

 shows whitish green on the underside, discolored with purple on the 

 upperside. The inside of the mine looks as if overgrown with a 

 small, whitish pearly fungus, and before I had examined it carefully 

 and found the larva and the early part of the mine I took the phenom- 

 ena to be the result of a fungous disease. Inside this roomy mine is 

 found a cn'lindrical, clear, transparent larva with sparse white hairs 

 and with 14 h^gs. Head is light brown with darker reddish brown 

 sutures and two black eyespots. 



When full grown, it is al)out 4.5 mm. long; it comes out of the mine, 

 turns vivid wine red, and spins a dense, oval, yellowish grey cocoon
