apex of the club, are ochre-yellow. 
The caterpillar is light brown, yellowish on the 
back, with two dark lines along the sides ; the spines 
are long and hairy, and two placed on the first seg-

than the rest. (See Plate III. Fig. 5.) It feeds on 
the dog’s violet and raspberry. The perfect insect is 
not uncommon in nearly all parts of England, and 
is found also in Scotland, but much less frequently.
