THE PLUM CURCULIO. 
larvae, and 1 cocoon of Triaspis curculionis, var. rufus. It thus 
appears possible that some few individuals may pass the winter in 
the soil, both in the adult stage and as pupse, and emerge the follow- 
ing spring. 
During 1905-6, at Fort Valley, Ga., adults were reared as early as 
May 22 and as late as October 5, an interval of 136 days. In this 
case the food for the late rearings was Crataegus.

At Siloam Springs, Ark., the interval of emergence, June 11 to 
September 3, includes 84 days. Later miscellaneous records of 
emerging adults reared from apples, however, were, up to October 
23, giving a total emergence interval of 134 days (see fig. 22).

The Washington, D. C, records show an interval from June 25 to 
August 21, 57 days. Other miscellaneous records for that locality 
give adults as early as June 15 and as late as August 30, or 76 days. 
Unquestionably adults are emerging even later.
