CURRANT. 



[11)00 



Cunaut branch infested by White 

 Woolly Scale. 



the brown roundish Scale at the 

 upper end lying almost at right 

 angles to the Currant shoot. In 

 the accompanying figure '■• of an 

 infested branch, these roundish 

 dark Scales are very noticeable 

 lying amongst the white wool. 

 At first this forms a white oval 

 mass, but afterwards the filaments 

 become drawn in all directions, 

 until at a distance the infested 

 branches look very much as if 

 they were covered over with white- 

 wash. 



The Scale itself is one-sixth 

 of an inch in length, and about 

 three quarters of its length in 

 width, of a squarish oval, with the 

 hinder extremity notched or heart- 

 shaped ; the colour reddish brown, 

 sometimes dark grey brown. A 

 line which is more or less raised 

 aloug the back gives it, to some 

 degree, the appearance of being 

 keeled ; and on each side of the 

 body it is wrinkled and faintly 

 pitted (when dried the wrinkles 

 are not very observable). See 

 fig. la, p. 48. 



The minute eggs, or egg-like 

 bodies, in the wool sent me in 

 1889 proved, when examined on 

 July 2nd, to have hatched, and 

 the orange-coloured larvae were 

 dispersing themselves in vast 

 numbers in the box in which the 

 spray of infested Currant was 

 fastened. These minute creatures, 

 which difi'er in being six-legged 

 and exceedingly active from the 

 immovable and legless state to 

 which they presently turn, were 

 of shape figured at " 2," p. 48 —
