WOOD-NYMPH MOTHS. 65 
ringed with lemon-yellow; caudal tuft deep lemon-yellow, 
with a black centre; palpi, fore-coxee and tibia lemon-yel- 
low, the latter banded with brown. 
Neglected plants, or plants infested with other insects 
or diseases, are more apt to harbor this and allied borers 
than plants which receive the proper atteution. 
THE PLUM TREE BORER. 
(Sesia pictipes G. & R.). 
This insect is by no means uncommon, and seems to be 
increasing in numbers as our plum trees grow older and be- 
come more numerous. The 
sexes of pictipes are similar 
and so closely resemble the 
male exitiosa that one may 
be readily mistaken for the 
other. The male is shown 
in Fig. 63. 
The larva of this borer 
feeds mainly in the trunks 
and branches of both culti-

vated and wild plums and 
in wild black and red cherries. The pruning knife is the 
best remedy we have against this insect. 
FAMILY AGARISTIDZ OR WOOD-NYMPH MOTHS. 
The moths belonging to this family are mostly beautiful 
insects, being either black, with large, white, yellow or red 
spots and patches upon their wings, or they have their 
front-wings white, margined with brown, and the hind- 
wings pale yellow. But few species are found, which fly 
chiefly during the day, but some of them are also attracted 
to the electric light.
