NORTHERN LIMIT OF OCCURRENCE. 
The data bearing on the distribution of the curculio to the north 
depend almost entirely upon records in the Reports of the Entomo- 
logical Society of Ontario and in Dr. James Fletcher's reports as 
entomologist of the Canadian Experimental Farms. The most 
northerly point is Aweme, Manitoba, previously mentioned in con- 
sidering the western occurrence of the insect. This is in north lati- 
tude about 49°. The insect is also recorded from Gore Bay, Mani- 
toulin Island, Ontario, north latitude about 46°, and at Ottawa 
and Owen Sound, Ontario. According to Prof. William Lochhead, 
the insect was quite prevalent in Quebec Province during 1909. 
There are three records from Nova Scotia, namely, Berwick, Wolf- 
ville, and Port William, all in the immediate vicinity of one another 
in north latitude 45° 30'. So far as we have been able to determine, 
the localities mentioned above mark the northern occurrence of the 
curculio. The insect apparently is quite prevalent throughout 
Ontario and the lower St. Lawrence region of Quebec Province. 
Table II gives these localities with the approximate north latitude 
and the bibliograpliical references.
