HICKORY. LEAVES. 
long, 0.02 broad, very pale yellow and at the tip watery white. 
The eyes appear like two minute brown dots widely separated, 
the head being short and broad with the transverse sutures 
between it and the other segments of the body very slight and 
indistinct. The legs and antennae are short and tinged with dusky. 
The antennae are three-jointed, the basal joint thickest and about 
as broad as long, the second joint globular and the third elongated 
and cylindrical, with a projecting point upon one side at the 
tip. When moving about the antennae appear to be employed as 
a fourth pair of legs, their points being pressed to the surface over 
which it is passing, similarly to the feet. The eggs are small oval 
shining grains of a watery yellowish white color. The young 
larvae are intermediate in size between the eggs and the females, 
and resemble the latter except that they are of an oval form and 
their beaks are proportionally longer reaching to or slightly beyond 
the tips of their bodies. 
These excrescences are common upon hickory leaves through¬ 
out the summer season. 
105. Hickory Thrips, Phlaothrips Caryie, new species. (Homoptera. 
Thripididse.) 
Slender conical protuberances like the spur of a cock a quarter 
of an inch long, standing out perpendicularly from the under 
surface of the leaf and closed at their end, with a similar protu¬ 
berance upon the opposite side of the leaf having its end open 
and split into several long slender teeth; within these galls a 
small slender shining black insect with the middle joints of its 
antennse honey-yellow and its long narrow white wings appressed 
to its back. 
Whether these singular galls, which resemble a long slender 
pod thrust half way through the leaf, are produced by the Thrips 
found in them, or by some other insect which forsakes them 
before this takes up its abode there, I am unable to say. In the 
instance in which I noticed them particularly, they occurred upon 
a young shag-bark hickory in the month of September. Quite a 
number of the leaves had one and several had two or more galls 
growing upon them, in each one of which was one or more of these 
insects or their larvae. The galls were of a very tough leathery 
texture, green where they adjoined the leaf and deep purple at
