INSECTS INJURIOUS TO THE CURRANT. 
THE SPINOUS CURRANT CATERPILLAR. 
(Vanessa (Grapta ) Progn °, Fabr.) 
Order of LEPIDOPTERA. Family of Nymphalidas. 
Fitch’s Third New York Rep., No. 142. 
A light-brownish or drab colored caterpillar, about one inch in 
length, thickly beset with white, branching spines, slightly tipped 
with black, and averaging in length about halt the width of the

and the abdomen broadly striped, with the same on the back and 
sides. There is a deep depression across the middle ot the back, 
on each side of which are two small silvery spots.

and three-quarters to two inches. It has scalloped wings, of a 
bright tawny or orange-red color, with black spots. On the under 
side the wings are entirely different, being of a blackish-gray color, 
paler at the tips, and with a small silvery mark on the hind wings, 
resembling the letter L.

caterpillar, it is evident that it must, ordinarily, have some other
