leaf which the caterpillar had first lined with a coating of silk. The 

 period of pupation is about nine or ten days. The moth of the sec- 

 ond brood has been observed abroad by me as early as June second. 

 Eggs are laid for the next brood, and the renewed 

 operations of the caterpillar upon the bushes are 

 soon to be seen, extending into July. It is possible 

 that there may be a third brood, as the transform- 

 ations among the Tortricidce may be quite rapid — the ^i«- 2i.-Front wing 

 pupal stage in some being limited to five days. I f^faVg e d.^'lMtoi 

 have seen the moths flying in my garden as late as July Zelier.) 

 twenty-fifth — the latest period at which I have been able to pursue my 

 observations upon it. From June second to the last days of July, and 

 probably into August, would be too long a time for moths of the 

 second brood to be seen abroad. It would be more in accordance with 

 what is known of other Tortricids if a third brood made its 

 appearance about the middle of July. 



Remedies. 

 The presence of this caterpillar on a rose bush may be detected at 

 a glance by the tied leaves at the tip of a stem, when it is only neces- 

 sary to give the little bunch a slight pinch, and its occupant is at once 

 destroyed. As it is seldom so numerous as to call for insecticidal 

 applications to the entire bush, which would require to be very 

 thoroughly applied in order to reach its food, this will be found the 

 most convenient and efficient method of destroying the pest. It is 

 the method that I have adopted in my own gai'den, where it is an 

 annual visitant, and where its pretty, broad-winged and conspicuously 

 marked moth is often to be seen by day during the months of June 

 and July, resting upon the leaves, or if disturbed, flying quickly for 

 a yard or two to a fence-board or other convenient resting j^lace, and 

 presenting much, in the pose of its wings, the appearance of some of 

 the smaller Noctuidce.
