is paler. Besides the quince, it feeds on the apple, cherry, 
plum, and sometimes the peach leaves. 
Remedies.—Gather and destroy the cases in which 
they hibernate. A small Ichneumon fly is a parasite on 
it; and the two-winged Tachina fly (Tuchina phycita, 
Le Baron), which closely resembles the common house 
fly, also preys on it. 
ATTACKING THE BUDS. 
21. THe TARNISHED PLANT-Bue (Lygeus lineola- 
ris, P. Beauv.).—This injurious insect is about one- 
fifth of an inch long. The males 
are generally darker than the females, 
the colors in both varying from a 
dark brown to a greenish yellow 
brown. The head is yellowish, with 
three narrow reddish stripes. The 
beak is about one-third the length 
of the body, and is folded under it 
when not in use to puncture the 
buds, and suck out their juices. 
These punctures seem to poison both 
the buds and young leaves. A whole 
branch is sometimes seen to wither and die from their 
injuries. The thorax has a yellow margin, with several 
yellowish lines running lengthwise. Behind the thorax 
is a yellow V-like mark, rather indistinct. The legs are 
yellow and the wings dusky brown. When handled they 
emit a disagreeable odor. ‘They do their mischief in 
about three weeks. They lay their eggs on the leaves. 
The young bugs are wingless, and of a green color. 
Otherwise they resemble their parents. They are in- 
jurious to the quince, pear, apple, plum, cherry, etc. 
Remedies.—They are sluggish, early in the morning, 
and may then be shaken off and destroyed.
