expanded wings. These latter are broad and flat, the outer 
edge of the fore-wings being rounded towards the base, and 
straight from the middle to the tip; they are crossed by 
irregular wavy bands, alternately of bright ochre-yellow 
and pale leaden blue; the yellow bands are 
varied with darker spots, the most con- 
spicuous of which is placed on the outer 
margin of the tip, and from this spot a

to the inner angle; the hind-wings and 
entire under surface are pale ochre-yellow. This moth is 
shown in Fig. 212, and also on Plate VIII. 
There are seasons in which these caterpillars are so 
numerous that whole trees, especially the smaller varieties 
of wild cherries, are entirely enclosed by several united webs, 
‘and all leaves are eaten, so that frequently ncthing is left 
but a few cherries, which, however, shrivel betore long. If 
numerous the unsightly webs should be removed with their 
occupants and should be burned. Any application with 
arsenical poisons would be useless at this time, as the leaves 
could not well be reached on account of the web enclosing 
them. 
THE CRANBERRY LEAF-ROLLER. 
(Cacoecia paralella Rob.). 
A few of these insects were observed during the middle of 
June in a swamp near St. Anthony Park, and a closer in- 
spection showed that a number of cranberry plants were 
webbed together. The caterpillars were about three-fourths 
of an inch long, reddish, with yellow heads, and a number of 
very prominent warts upon their backs; from each one of 
these tubercles grew one or more rather long and stiff hairs. 
None of these caterpillars pupated in confinement, but as
