WHITE WOOLLY CURRANT SCALE. 



77 



of Dr. Signoret's scientific 

 description. My own more 

 general description, from 

 specimens examined on 

 June 2nd, is as follows : — 



The Scale itself (see fig. 

 la, p. 76) dark grey-brown, 

 rather longer than broad 

 (the specimens measured 

 from one-eighth to three- 

 sixteenths of an inch in 

 length, and over one-eighth 

 of an inch in width), of a 

 squarish oval, with the 

 hinder extremity notched 

 or heart-shaped, and in 

 their then dried state the 

 fore part turned up so 

 much as to be reflexed; the 

 keel along the back was 

 still partly observable, with 

 slight ridges running down 

 to the edge of the Scale. 



The white cottony or 

 woolly matter (figured at 1, 

 p. 76) which forms the 

 nest of the eggs, and of 

 the young Scales in their 

 earliest condition, formed, 

 where it was undisturbed, a 

 compact tuft, on the front 

 part of which the Scale it- 

 self was raised, sometimes 

 almost vertically. Whilst 

 fresh, the Scale and its 

 white wool formed together 

 a somewhat oval mass, 

 which presently became 

 drawn out in all directions, 

 so that in the distance the 

 infested branches looked as 

 if they were scattered over 

 with whitewash (see ac- 

 companying figure, from a 

 photo kindly taken for me 

 by Mr. T. P. Newman, of 

 Haslemere).
