INSECTS INJURIOUS TO THE RASPBERRY 



portion overhung by the long hairs of the next segment. 

 The under side is greenish brown, with a few small clusters 

 of short brown hairs. 



The larva changes to a brown chrysalis within a rather 



tough cocoon formed of pieces of leaves interwoven with silk. 



The moth (Fig. 325) has the fore wings gray, mottled with 



spots, streaks, and dots of darker shades of gray and brown. 



The hind wings are of a dull pale 

 gray, deepening in color a little 

 towards the outer margin. The 

 under surface is paler than the 

 upper. When the wings are ex- 

 panded, they measure about an inch 

 and a quarter across. 

 Should this insect ever become troublesome, it may be sub- 

 dued by hand-picking, or destroyed by showering the bushes 

 with water in which hellebore or Paris-green has been mixed, 

 in the proportion of an ounce of the former or one or two 

 teaspoonfuls of the latter to two gallons of water.

No. 182. — The Raspberry Plume-moth. 



Oxyptilus nigrocUicUus Zeller. 



The caterpillar of this pretty little plume-moth has not 

 in any instance on record been sufficiently numerous to 



be considered destructive, yet 

 it is an interesting insect, and 

 on this account deserves a pass- 

 ing notice. About the middle 

 of June the larva reaches full 

 growth, when it is about four- 

 tenths of an inch long, of a pale 

 yellowish-green color, streaked with pale yellow, and with 

 transverse rows of shining tubercles, from each of which arise 

 from two to six spreading hairs of a yellowish-green color. 

 The head is small, pale green, with a faint brown dot on each 

 Bide. Fig. 326 represents this larva, much magnified.
