LE I.—ON NEW AND IMPERFECTLY KNOWN STRAW¬ 
BERRY INSECTS. 
Note on the Life History of the Strawberry Slug. 
(Emphytus maculatus, Norton.) 
i 
Order Hymenoptera. Family Tenthredinim. 
(Plate VII. Fig. 1.) 
ry article on strawberry insects published in my report for 
found myself obliged to leave in doubt an important point 
life history of this insect owing to the conflict of observa- 
s reported by previous writers on this species. 
le fullest and most authoritative article upon it, that by Mr. 
n his Ninth Report as State Entomologist of Missouri, the 
mt is made that it is double brooded, the adult flies of the 
ood appearing by the end of June and the beginning of July. 
• the influence of July weather,” he says, “the whole process 
depositing, etc., is rapidly repeated, and the second brood of 
descend into the earth during the fore part of August, and 
heir cocoons, in which they remain in the caterpillar state 
i the fall, winter, and early spring months, till the middle of 
Dllowing, when they become pupte and flies again as related.’’ 
the other hand the observations of Mr. Saunders, made in 
l, Ontario,* those of , Mr. Galusha and Miss Smith, in Central 
, as reported in the Transactions of the State Horticultural 
', and the statements of Prof. French, in Southern Illinois, 
ied in the same Transactions; together with those of 
dice B. Walton, relating to the life history of this species 
! latitude of Muscatine, Iowa;—all report the absence of 
rnd brood, or report their failure to detect it, the dates 
oy Mr. Saunders being, in fact, inconsistent with it.f The 
hus left in uncertainty is practically the most important in 
3 history of this insect, since if two broods occur (the second 
ing after the fruit is gathered), the multiplication of the 
. may be easily and cheaply arrested by the application of 
th Report of the Ontario Entomological Society, page 18.
