HICKOEY. LEAVES — HICKORY TUSSOCK- MOTH. 159 



The larvcs which occur in the walnut galls are of different sizes, the largest being 

 0.025 long, of an oval form and a light yellow or yellowish "green color, with dusky 

 legs and antennae. Younger individuals are white, shining, and somewhat hyaline, 

 with pellucid white legs. The antennas are short and robust, consisting of two short 

 thicli basal joints and a longer terminal one of a conical form, and giving off a short 

 bristle on one side near the tip. The logs are also short and thick. 



The WINGLESS FEMALES, ofwhicb one is found in each gall, she being the parent 

 of the multitude of larvas around her, measures 0.04 in length, or somevphat more. 

 She is of a plump egg-shaped form, narrower posteriorly and flattened on the under 

 side. The segments of the abdomen are much longer than those of the thorax, and 

 are separated by impressed lines. The legs are short, scarcely projecting beyond 

 the outer margin, and with the antennae are blackish, the general color of the body 

 being yellow, often of a dull or dirty tinge. 



Trees are much disfigured by the excrescences upon the ends of 

 the limbs which this louse produces, which show conspicuously 

 after the leaves have fallen. It requires two or three years for 

 them to decay and become obliterated, and in ifee mean time a 

 new stock is annually added, for where these insects obtain a lodg- 

 ment they continue year after year, stinting the tree in its growth 

 and blasting its fruit. Though there sometimes grows upon such 

 trees nuts which are full sized and appear externally to be fair 

 and well formed, they are found upon cracking to be destitute of 

 meats. 



It is quite probable that these insects may be expelled from the 

 tr'ees which they infest by rubbing the ends of the limbs with soft 

 soap soon after the leaves put forth. Or a month afterwards, 

 when the galls are green and filled with lice, by cutting off and 

 burning all the twigs and leaf-stalks on which these galls are 

 growing, the tree will probably be relieved from a renewed at- 

 tack the following year.
