NOTONECTA UNDULATA SAY PRKVLVG ON THE KGGS OF 

 BELOSTO.\fA ( = ZA/T/fA AUC IT.) FLUMIXEUM SAY. 



BY HENRY H. P. SEVERIN AND HARRY C SEVERIN. 



A few undulating back-swimmers, Notonecta utufnlatn, were placed as 

 food material in a glass-jar of water containing a male specimen <»f 

 Belostoma flutnintum bearing eggs on its back. Several days later it was 

 observed that the only surviving Notonecia was feedinj^ in a righted 

 position on the eggs, while the Belostoma was clinging quietly, back up- 

 ward, to an object on the bottoui of the jar. The back-swimmer was 

 disturbed several times at its meal, but after swimming about for a short 

 while it would again return to feed on the eggs. The interesting point of 

 the observation was, that during the entire process of feeding, the 

 Notonecta was always in a righted position. 



Thk .Annual Meeting of the Kntomological Society of Ontario will be 

 held at the Ontario .Agricultural Collejje, Guclph, on I'hursday and 

 Friday, November 3rd and 4th.
