 Typhlocyba conies (grape leaf -hopper) on red grapes in the Niagara 

 district ; Alonojyhadnus rubi (raspberry sawfly) on raspberry ; Aegeria 

 tipidiformis (imported currant borer) on currants ; Sideniia (Hadena) 

 devastairix (glassy cutworm) on wheat and barley ; Anthonomus 

 signatus (strawberry weevil) ; Hylemyia antiqua {Pegomyia ceparum)

Pupae of the forest tent caterpillar {Malacosoma disstria'] were 

 parasitised in some localities to an extent of 90 per cent, by the Sarco- 

 phagid, Sarcophaga aldrichia, Parker. Eggs of the Tachinid, Dory- 

 phorophaga (Phorocera) doryphorae were observed on the Colorado 

 potato beetle [Leptinotarsa decemlineata] in one district. This is a 

 common parasite of the potato beetle ; the eggs are deposited on the 

 host during June, and nearly full-grown larvae have been found early 

 in July. Eggs and adults have again been observed in the middle of 

 September.
