556 NEW YORK STATE MUSEUM 



Chlorotettix lusoria O. & B. One example taken near the Ausa- 

 ble river. Also taken Sep. 22, 1902. 



Cicadula 6-notata Fallen. Summit of Mt Whiteface and more 

 abundantly on the lower levels about Lake Placid. 



Cicadula slossoni VanD. Common in grass on the Lake Placid 

 Club grounds. The males are considerably smaller and darker 

 in color than the females. 



Cicadula variata Fall. One pale example. 



Gnathodus punctatus Thungb. Common. 



Gnathodus viridis Osb. One example taken on the summit of 

 Mt Whiteface. 



Dicraneura communis Gillette. Several examples were taken 

 on the summit of Mt Whiteface. I have also taken this species 

 at Phoenicia, Ulster co., and at Lancaster, Erie Co., N.Y. 



Empoasca atrolabis Gillette. Not uncommon on bushes in open 

 woods. 



Empoasca flavescens Fabr. One example from near the Ausa- 

 ble river. 



Eupteryx vanduzei Gillette. One example taken in the rich 

 swampy woods near Isham's. This specimen has the costa con- 

 spicuously pale yellow bordered within by a black vitta. 



Eupterjrx flavoscuta Gillette. A very dark specimen is among 

 the material taken on the summit of Mt Whiteface. Others were 

 taken on Cobble Hill and in that vicinity. It lives on ferns and 

 is widely distributed. 



Typhlocyba rosea Linn. From the golf links of the Lake Placid 

 Club. . 



Typhlocyba tenerrima H. S. One example from near the Ausa- 

 ble river. 



Typhlocyba querci Fitch. Summit and slopes of Mt Whiteface. 

 I also took this species at Kingston and Phoenicia in the Catskills. 



Typhlocyba sp. Beaten from a thorn bush in an opening in the 

 woods near "Balance rock." 



Trioza tripunctata Fitch. Taken at Axton by Professor Mac- 

 Gillivray. 



Psylla sp. Six species of this genus and three of Li via were 

 taken by me about Lake Placid. So little has been done with our 

 North American species in this family that it is quite useless to 

 attempt the determination of our material at present. Probably 

 no family of our Hemiptera is so much in need of careful and con- 

 scientious study by a competent student as this.
