THE CANADIAN ENTOMOLOGIST. 139 



is a wide yellow stripe down the back, and another of the same character 

 along each side, but somewhat broken. The under side is white, with a 

 •slight tinge of pink, and also spotted with black, with a wide yellow stripe 

 down the middle. The feet are blackish ; prolegs yellow, dotted with 

 black. 



When full grown, the larva descends to the earth and buries itself a 

 little below the surface, where it is transformed into a dark brown chrysalis 

 about half an inch long, and remains in this inactive state from two to 

 three weeks. 



The moth, see fig. 23 (after Riley), is of a pale yellowish color, with 

 :several dusky spots varying in size, form and distinctness in different 

 specimens ; sometimes they are so arranged as Fig. 23. 



to form one or two irregular bands across the 

 wings ; when these latter are expanded they 

 measure about i}( inches. Soon after the 

 moths escape they pair and shortly the female 

 deposits her eggs on the twigs and branches of 

 the gooseberry and currant bushes, where it is 

 said they remain unchanged until the following spring. 



This insect is a native of America, and was formerly confined to the 

 Avild gooseberry and currant bushes, on which we still occasionally see 

 1;hem. The larvae are found in various stages of their growth, from the 

 ist to about the 20th of June, and will feed on the black currant as well 

 .as on the red and white currant and gooseberry. The moths begin to 

 appear during the first days of July, and are very common for two or three 

 weeks following. 



Powdered hellebore mixed with water and used with a watering pot, 

 or Paris green mixed with twenty times its weight of flour and dusted on 

 the bushes, will be found effectual remedies for the destruction of this 

 caterpillar. The habit it has of letting itself down from the bush with a 

 silken thread, and remaining suspended, may also be turned to practical 

 account in its capture, for if, after tapping the infested bushes, a forked 

 stick or some similar instrument is passed under it, all the hanging threads 

 may be caught and the larvae drawn out in groups and crushed with the 

 foot.
