Mr. Wintersteiner contributed local specimens of Tropisternus mixtus, 

 Creniphilus digestus, and Berosus aculeatus to the Local Collection, and a note 

 on the occurrence of Brachybamus electus on the water plant Myriophyllum. 



Mr. Wintersteiner also placed on record the breeding of a species of the 

 Dascyllid genus Cyphon ^om aquatic lar\-3e. The larvae were found in March 

 in a stagnant pond at Forest Park, among dead leaves under a tree, and were 

 about ten mm. long. Two dozen were taken home and kept in a glass vessel, 

 but on account of their cannibal habits two only reached maturity ; the pupae 

 were fastened to the glass by threads from the anal extremity and hung head 

 downwards.
