the skin, of? the stem below the buds. Dr. Chapman has 

 carried this point farther, as he found the caterpillar " in firm 

 little cocoons under the scales of the buds for next year clearly 

 in a hibernating condition." And, as seen just when they had 

 left the currant, and as seen later on by Dr. Chapman in their 

 cocoons, these caterpillars had not arrived at their full growth, 

 as they were only about the eighth of an inch in length, whereas 

 in the spring, as found in the currant buds, they are nearly 

 double this length when full grown. 



In its early stages the caterpillar is reddish. After feeding in 

 the currant buds it becomes green with a tinge of yellow. It has 

 a black head and blackish marks on the second segment, and an 

 orange-coloured mark between the seventh and ninth segments. 

 The prolegs are black. The figure of the caterpillar (Fig. 1. d} 

 represents it when near pupation. 



The pupa is of a greenish colour with a brown shade. 



METHODS OF PREVENTION AND REMEDIES. 



Picking off the infested buds has been practised in some 

 plantations, but this is obviously a tedious and costly process, 

 and can hardly be recommended upon a large scale. Where 

 infestation is considerable and the bushes have been seriously 

 injured by the caterpillars it would be well to cut the bushes 

 hard in order to remove the infested branches as much as pos- 

 sible. Or, the bushes, after they have been well pruned, might be 

 brushed over with soft soap and paraffin, or syringed just before 

 the buds burst forth, with a mixture of soft soap and paraffin, 

 or a strong solution of quassia with soft soap. All cuttings 

 should be burnt at once, and not left on the ground.
