﻿28 NINTH ANNUAL KEPORT

They are of a pitchy black color, with two rows of large, transverse^ 

 dull, whitish spots upon the abdomen. The female, with the saw-like 

 instrument peculiar to the insects of this family, deposits her eg^s by 

 a most curious and interesting process, in the stems of the plants^ 

 clioging the while to the hairy substance by which these stems are 

 covered. The eggs are white, opaque, and 0.03 of an inch long, and 

 may be readily perceived upon splitting the stalk, though the outside 

 orifice at which they were introduced is scarcely visible. They soon 

 increase semewhat in bulk, causing a swelling of the stalk, and hatch 

 in two weeks — more or less according to the temperature — and 

 during the early part of May the worms attract attention by the innu- 

 merable small holes they make in the leaves. Their colors are dirty 

 yellow and gray-green, and when not feeding, they rest on the under 

 side of the leaf, curled up in a spiral manner, the tail occupying the 

 center, and fall to the ground at the slightest disturbance. After 

 changing their skin four times they become fully grown, when they 

 measure about | of an inch. 



At this season they descend into the ground, and form a very 

 weak cocoon of earth, the inside being made smooth by a sort of 

 gum. In this they soon change to pupse, from which are produced a 

 second brood of flies by the end of June and beginning of July. 

 Under the influence of July weather, the whole process of egg depos- 

 iting, etc., is rapidly repeated, and the second brood of worms descend 

 into the earth during the forepart of August, and from their cocoons, 

 in which they remain in the caterpillar state through the Fall, Winter^ 

 and early Spring months, till the middle of April following, when 

 they become pupsB and flies again, as related. 



REMEDIES . 



The same remedies recommended for the Currant Worms will 

 apply here. They are more satisfactorily employed, however, and 

 after the worms have been made to fall to the ground, a mixture of 

 warm water and kerosene will destroy them as quickly a? anything.
