prominent in some specimens than in others, forming some- 

 times one or two irregular bands across the wings. When 



expanded, the wings measure about

a brief period the female deposits her 

 eggs for the next year's brood on the 

 twigs and branches, where they en- 

 dure the heat of the remaining por- 

 tion of the summer without hatching, 

 and the piercing cold of the succeed- 

 ing winter without injury, awaiting the arrival of their proper 

 time for development the following spring. 



Remedies, — Powdered hellebore, which is so speedy and 

 certain a remedy in the case of the saw^-flies, does not act with 

 the same promptitude in this instance. This larva seems to 

 be much hardier and more difficult to destroy with poisonous 

 substances; hence, if hellebore is used, the liquid should be 

 made twice or three times the usual strength. Paris-green is 

 more certain and effectual where there is no objection to its 

 use. Hand-picking is more practicable with this larva, on 

 account of its habit of letting itself down by a strong silken 

 thread and remaining suspended ; and if after striking the 

 bush a forked stick is passed all around under it, all the 

 hangiiig threads may be caught, and the larvae drawn out in 

 groups and crushed with the foot. This insect is quite de- 

 structive to the black currant, and also to the gooseberry. 



No. 209. — The Spinous Currant Caterpillar. 



Grapta po^ogne (Cram.). 



The parent of this caterpillar is a very handsome but- 

 terfly, which is shown in Fig. 360 ; the pair of wings 

 which are attached to the body show the upper surface, the 

 detached pair the under surface. Above, the fore wings are 

 of a dull reddish orange, widely bordered on the outer edge 

 with dark brown, while within there are many spots of brown 

 and black. The hind wings are dark brown, tinged with red
