■der side of the leaves and on the principal veins. They 

 hatch in from ten to twelve days. The larvae eat little 

 holes in the leaf until nothing but the frame work or skele- 

 ton is left. When ready to pupate they form their cocoons 

 under rubbish; sometimes in the ground, occasionally on 

 the stems or leaves of the currant bushes. The flies 

 emerge during the latter part of June or the first of July. 

 These lay eggs, which soon hatch, and the larvae generally 

 change into the pupa state, in which they pass the winter. 

 Remedies. Parasites prey on the egg and on the 

 larvae, notably one found by Prof. Lintner, State Entomol- 

 ogist of New York, which attacks the egg. Dr. Packard 

 recommends powdered white hellebore sprinkled over the 

 bushes by means of a muslin bag tied to a stick. Dr Wor- 

 cester has met with equal success in the use of carbolate of 

 lime, which was sprinkled over the bushes as soon as the 

 worm made its appearance. Hand picking is very good.
