which wriggles quickly out of its case and drops to the 
ground as soon as disturbed. 
All these insects are rather difficult to exterminate on 
account of their method of living in protecting folds, but 
repeated spraying at the proper time with arsenical poisons 
will prove successful. 
THE OBLIQUE-BANDED LEAF-ROLLER. 
(Caccecia rosaceana Harr.). ° 
This is a very common insect found upon the apple, 
plum, cherry, rose, raspberry, gooseberry, currant, straw- 
berry and other plants. In some seasons it is decidedly 
injurious, and many complaints are made, especially by 
lovers of the rose, whose pets are disfigured by the presence 
of such worms. When mature they are about three-quarters

unfold; they roll up and fasten together the still tender 
leaves which furnish them both shelter and food. When 
mature the caterpillar prepares its old dwelling place into a 
safer retreat by lining its inside with silk; it now changes 
to a pupa of a dark-brown color, from which issues towards 
the end of June or early in July the winged insect, shown in 
Fig. 211, Plate VIII. 
This and a few other closely allied moths are character- 
ized by a peculiar form; when their wings are folded they are 
short, broad and flat insects, resembling bells in outline; the 
expanded wings are very much arched on the front edge, 
curving in a contrary direction near the tip. The body of 
the moth is reddish-brown, the fore-wings of a light cin-
