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 (Tachina pliycitcB, 

 Le Baron), which closely resembles the common house 

 fly, also preys on it. 



ATTACKING THE BUDS. 



21. THE TARNISHED PLANT-BUG (Lygceus 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 



TjaJSffiZfjjL brown. The head is yellowish, with 



/ISSPffX 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.

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.
