Notes and Exhibitions. 

 Mr. 0. H. SwEZEY exhibited specimens of three species of 

 Midges and read " Notes on some Cecidomyidae not previously 

 reported in Hawaii." 



1. Diplosis sorghicola Coq. was bred from the tops of sorg- 

 hum. The larvae feed on the juices of the growing seeds caus- 

 ing them to blight. They pupate in the same place v/here they 

 feed. 



2. Diplosis sp. was bred from larvae feeding upon the spores 

 of a rust on sorghum leaves. These drop to the ground to pupate. 



3. Contarina solani was bred from tomato buds where the 

 larvae fed upon the young ovary of the blossom causing the buds 

 and blossoms to blight and eventually fall off. The larvae of 

 this species also pupate in the ground." ...

 notes taken during the year on the occurrence, habits and life- 

 cycle of this recently discovered insect-enemy of mangoes in

 called to my attention. The first specimen observed was a pupa 

 that Mr. J. E. Higgins had discovered within the seed of a mango 

 that he had collected at Mr. Allan Herbert's former place in 

 Kalihi, Oahu. Two days after, July 7th, I visited the Moanalua 

 Gardens where I knew Mr. Maclntyre, the Superintendent, to be 

 planting seeds and there found within seeds of various varieties 

 what I considered unquestionably the larvae, pupae and adults 

 of the same species. On July 9th, the pupa collected by Mr. 

 Higgins developed into an adult, confirming the identity of the 

 specimens taken at Moanalua. • Mr. Maclntyre was not remov-
