HICKORY. LEAVES. 



long, 0.02 broadj very pale yellow and at the tip watery white. 

 Tlie eyes appear like two minute brown dots widely separated, 

 tlie 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 antennse are short and tinged with dusky. 

 Tlie antennse 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 antenna? appear to be employed as 

 a fourth pair of legs, their points being pressed to the surface over 

 whicli 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. 



165. Hickory Thrips, Phlceothrips Carya, new species. (Ilomoptera. 



Thripididae.) 



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. 



Wliether these singular galls, which resemble a long slender 

 pod thrust half way through the leaf, are produced by the Tlirips 

 found in them, or by some other insect which forsakes tliem 

 })elure tliis takes up its abode there, I am unable to say. In the 

 instance in wliich I noticed them particularly, tliey occurred upon 

 a young shag-bark hickory in the month uf September. Quite a 

 number of tlie 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 larvse. The galls were of a very tough leathery 

 texture, green where they adjoined the leaf and deep purple at
