THE JUMPING PLANT-LICE OR PSYLLID^ OF THE NEW WORLD. 151 



PSYLLA CARPINICOLA, new name. 



Figs. 86, 91, 262, 317, 473, 478. 

 Psylla carpini Fitch '51:— Riley '83:69.— Lintner '93:64. 



Length of body (male) 2.1 mm.; (female) 2.7 to 3; length of fore 

 wing 3; width of head 0.87. General color greenish yellow, antennae 

 black at tips and on apices of four terminal segments. 



Head broad; vertex usually not deeply impressed discally, nearly 

 half as long as broad, emarginate in front at median line; genal cones 

 as long as vertex or often longer, acute to subacute at apex, moderately 

 divergent, pubescent, scarcely dcfiexed from plane of vertex. Anten- 

 nae long and slender, fully two and a half times as long as width of 

 head. 



Thorax typical in form. Hind tibiae with a distinct spur at base. 

 Wings rather clear, sometimes shghtly yellow but never so much as 

 in striata, venation similar to that of striata. 



Genitalia. — Male. — Anal valve long, narrowed apically, tip broad- 

 ened somewhat, densely pubescent; forceps long, shghtly narrowed 

 midway, with a black tooth at apex. Female. — Genital segment 

 longer than rest of abdomen, moderately thick at base and converging 

 to an acute apex; dorsal valve longer than ventral. 



Described from several males and females from Polk County, Wis- 

 consin (Baker); Ames, Iowa (Mally), July 1, 1894; Ormsby County, 

 Nevada (Baker). Several of these specimens have been identified 

 as P. carpini by C. V. Riley and others, though how authentic this is, 

 is not certain. 



Forster, in 1848, named a European species carpini. Although this 

 is a synonym of Psylla mali, yet it invalidates Fitch's carpini which 

 was described in 1851. In order not to change the name too much, 

 since it is so famihar, I have assigned to it the name carpinicola. 



PSYLLA CEPHALICA, new species. 

 Figs. 90, 263, 309, 475. 



Closely related to carpinicola, but a httle larger and broader; head 

 distinctly broader, sometimes about 1 mm broad; vertex flatter; 

 genal cones larger, broadly rounded and only a Httle divergent, about 

 as long as vertex or shorter; antennae equally long and slender. 

 Legs rather stout. Wings more yellow than in carpinicola but less 

 than in striata; long branch of cubitus (CuJ distinctly more arched 

 than in either of the above species. 



Described from several males and females from Texarkana, 

 Arkansas (R. A. Cushman) on Carpinus caroliniana, March 20, 1907; 

 Marshall, Texas (Cushman), on Rubus, March, 1907; Washington, 

 District of Columbia (Schwarz), August; Mud Creek, Tompkins 

 County, New York, in June, 1904 (determined by Miss Patch as
