﻿OF THE STATE ENTOMOLOGIST 11 



Mr. Saunders has found as many as 101 eggs on three contiguous 

 leaves. 



The eggs hatch within a week or ten days according to tlie 

 weather, into pale 201egged larvae with a large dull whitish head, 



having each side the black spot 

 so characteristic of Saw-fly lar- 

 va3 belonging to the same genus. 

 The color soon becomes green, 

 and as the worms molt they ac- 

 quire black, shiny spots on the 

 body, and a black head. After 

 J, J the last molt the spots are shed 

 again, and the color \i entirely 

 grass-green, except the dark

 an enlarged view of one of the abdominal joints in profile, so as to 

 exhibit the position of the black spots. '* When full grown the larvae 

 are about three quarters of an inch long, and from their greatly 

 increased size, make their presence readily known by the sudden dis- 

 appearance of the leaves from the infested bushes. Shortly after- 

 wards, having attained a length of fully three-quarters of an inch, 

 they burrow under ground, generally beneath the infested bushes, 

 or, if there are many leaves lying on the ground, simply hide under 

 those leaves. In either case they spin around themselves a thin oval 

 cocoon of brown silk, within which they assume the pupa state." 

 Frequently, however, as has been fully proved by Mr. Saunders, and 

 as has been recorded by European observers, they form their cocoons 

 in the open air, on Ihe bushes, or under any extraneous shelter that is 

 at hand. "About the last week in June or the first part of July, or 

 occasionally not until the beginning of August, the winged insect 

 bursts forth from the cocoon and emerges to the light of day; when 

 the same process of coupling andlayins: eggs is repeated. The larvae 

 hatch out from this second laying of eggs as before, feed on the leaves 

 as before, and spin their cocoons as before ; but the perfect fly from 

 this second brood does not come out of the coccoon till the following 

 spring, when the same series of phenomena is repeated," At least 

 such is the case ordinarily, though a third generation is sometimes 

 produced.
