INSECTS INFESTING THE RASPBERRY. 



which is finally transformed into a slender blackish beetle, 

 with the head and thorax of a brilliant copper color.] 



The location of these borers in the canes may easily be detected 

 by the gall-like swelling in the canes ; this swelling is about an 

 inch long, and is very rough as compared with the rest of the 

 cane. Occasionally several larva' will l)e found inhabiting the 

 game gall, thus lengthening the latter and causing it to assume 

 a very irregular shape. 



Fig.'lOy.— Rasp]»erry Borer, en- 

 larged ; h, the larva — color, yel- 

 lowish; o, the hind part of its 

 body still more enlarged ; c, the 

 beetle — colors, black and cop- 

 pery-red. 



When fully grown, the larva 

 (Fig. Idlh) measures about seven 

 lines in length, and is of a yel- 

 lowish-white color ; the first segment behind the head is greatly 

 dilated on each side, and the last segment is armed with two 

 dark brown horns, each with three teeth on the inner edge. It 

 assumes the pupa form within the gall in April or May, and 

 the perfect beetle (Fig. 197c) issues in the course of a few weeks. 



This spQcies has been reported to me as infesting the Idack- 

 berry in this State, l)ut I have not seen any specimens.
