SOUTHERN LIMIT OF OCCURRENCE. 
The most southerly location in the United States from which we 
have records of this species is Victoria, Tex., in the southwest, and 
around Hampton, Fla.,in the southeast. At the latter place the insect 
has been found very abundantly and it constitutes a very serious 
pest to peach growers. At Deland, Fla., to which is adjacent a 
considerable peach-growing industry, no trace of the insect could be 
discovered, although it should undoubtedly thrive in that locality. 
These observations, however, were made in 1905 and the insect in the 
meantime may have become established there. 
DISTRIBUTION OF THE CURCULIO ACCORDING TO LIFE ZONES. 
From the foregoing discussion it will be noted that the plum 
curculio is present in the humid area in all of the life zones except 
the Tropical. It is most abundant and destructive, however, in the

Upper and Lower Austral Zones. While generally present through- 
out the Transition Zone it would appear to be much less of a pest 
than to the southward. Sufficient data are not at hand to indicate 
its relative importance in the Canadian Zone, though it is probably 
occasionally quite destructive, as indicated by the observations of 
Dr. Fletcher, Prof. Lochhead, and others. In figure 4 the shaded 
area indicates the present distribution of the curculio in so far as we 
have been able to determine it.
