honey-yellow, with the tips of the six tarsi, and sometimes 

 the extreme tips of tlie hinder tibije, and of the tarsal joints, 

 pale dusky for a quarter of {heir length. The wings are 

 partly hyaline, with black veins, a honey-yellow costa, and a 

 dusky stigma, edged with honey-yellow. The male differs 

 a little in having black coxae. Mr. "Walsh states that the 

 larva is a pale grass-green worm, half an inch long, with a 

 black head, which becomes green after the last moult, but 

 with a lateral brown stripe meeting with the opposite one on 

 the top of the head, where it is more or less confluent ; and 

 a central brown-black spot on its face. It appears the last 

 of June and early in July, and a second brood in August. 

 They spin their cocoons on the bushes on which they feed, 

 and the fly appears in two or three weeks, the speciniens 

 reared by him fl3'ing on the 26th of August." This worm 

 may at once be distinguished from the imported currant 

 worm by the absence of the minute black warts that cover 

 the body of the latter. The same remedies should be used 

 against this worm as were recommended for the imported 

 saw fly.
