ig6 Brown Scale of Gooseberry and Currant, [june, 



in sheltered spots, especially on wall-trained trees in a 

 fairly sunny aspect, and no plant suffers in such situations 

 so much as the cotoneaster. 



There can be no doubt that this insect is a mere phyto- 

 phagous variety of the peach scale (L. persicae), differing only 

 by its usually smaller size, its more rotund or hemispherical 

 form, and the more marked character of the blackish, trans- 

 verse bands in the immature stage. Apart from these 

 exceptions the description of the one serves equally for the 

 other, and the methods of control herein described will serve 

 equally well for both kinds.

Description and Life History. — The young gravid female 

 (Fig. 2) is short and ovate in form, being a little longer than 

 it is broad, flat beneath and highly convex above. The colour 

 of its upper parts varies from dusky ochreous-yellow to greenish 

 yellow, with eight or nine more or less interrupted, blackish, 

 transverse bands, of which the anterior one is the broadest, 

 the rest diminishing in width as they approach the hinder or 

 cleft extremity of the body. The legs and antennae are 

 retained, but the insect loses all power of locomotion long 

 before the period of gestation commences. As the insect 

 matures the pale colour gradually changes to bright chestnut
