Insect Pests. 



with a series of from 60 to 70 transverse rings, furnished with regular 

 rows of circular projecting processes, only at the sides of the body 

 can these be recognised as projections. There are four legs placed at 

 the anterior end of the body, two on each side of the head. A small 

 bristle appears on the underside of the second segment ; a very long 

 bristle extends from the upper side of the third segment, a shorter 

 one from the upper side of the fourth, while two bristles arise from 



the terminal segment, a short one 

 from the inner side and a long one 

 from the outer side near the base ; 

 this terminal segment, on the upper 

 side near the end, is furnished with 

 a strong, blunt claw, and at the 

 extremity with a shorter process, 

 with five bristles extending from 

 each side of it. 



There are five pairs of bristles 

 on the body, the first of which are 

 placed on the under surface midway 

 between the base of the legs and the 

 second pair of bristles ; these latter 

 are much longer and situated slightly 

 anterior to the middle of the body. 

 The next pair are very short and are 

 placed on the ventral side of the 

 body ; another comparatively short 

 but slightly longer pair are placed 

 near the posterior extremity, on the 

 ventral side ; and the fifth pair, which 

 are the longest of all, arise from just 

 behind the anal extremity. The head 

 ends in a. blunt, snout-like projection 

 including the mouth parts, which 

 consist of a pair of maxilla- and a 

 pair of mandibles, the mouth being 



adapted for biting and sucking. The cephalo-thorax is protected 

 above by a triangular shield marked with longitudinal furrows. 

 That portion of the body below the caudal pair of bristles acts as a 

 sucker, and is used by the mites as a means of attachment to the 

 food plant while they wave their bodies and legs in the air (a 

 performance which they go through when any diseased bud is opened, 

 one mite being capable of thus holding up several of its companions).
