THE JUMPING PLANT-LICE OR PSYLLlDiE OF THE NEW WOELD. 43 



Head broad, but not as broad as thorax, very uniformly rounded 

 downward in front; vertex rather large, converging toward front; 

 frons unusually large, a heptagonal sclerite visible from in front, 

 broadest at ocellus, continuing uniformly the surface of vertex and 

 gense; gense large, swollen lobately on each side beneath antennal 

 bases, with a long hair at lowermost point; clypeus rather large; 

 (antennae broken). 



Thorax well arched, coarsely punctate or stiigate; pronotum long. 

 Hind tibiae with a spur at base. Wings long, hyaline, transparent, 

 about two and two-thirds times as long as broad, narrowed toward 

 apex, rounded at tip; first marginal cell broader than in ilicis; ptero- 

 stigma long, broad at base. 



Oenitalia. — Female — Genital segment about half as long as rest of 

 abdomen, acute; dorsal valve a httle longer than ventral, with a tuft 

 of hairs dorsad. 



Described from one female from Escuintla, Chiapas, Mexico (Craw- 

 ford), July 25, 1910.

Figs. 102, 103, 10-J, 105, 108, 410. 



Psylla ilicis Ashmead '81: 225. 



Aphalara ilicis Riley '83: 69. 



N. B. — Psyllopa ilicis Crawford '11c: 632 is a different insect. 



Length of body 2 mm.; length of forewing 2.6; width of head 0.93. 

 General color flavous; antennae brown. 



Head uniformly rounded down and forward as in magnifrons; frons 

 smaller, similar in position; genae less swollen, making head appear 

 more as a longitudinal portion of a cylinder. Antennae about twice 

 as long as width of head, not very slender. Cl3rpeus large, conical, 

 perpendicular. Thorax moderately broad. Propleurites rather large, 

 with pleural suture oblique. Legs rather short; hind tibiae without 

 spur at base. Wings hyaline, elongate-ovate, venation typical of 

 genus; fii-st marginal cell elongate; pterostigma large. 



Genitalia. — Male. — Genitalia as in A])lialara; anal valve with a 

 similar long, caudal projection from the perpendicular axis; forceps 

 slender, converging to an acute point, bowed. Female. — Genital 

 segment about as long as rest of abdomen, very acutely pointed, 

 dorsal valve a little longer than ventral, with long pubescence dorsad. 



Described from eight males and females from Savannah, Georgia 

 (Schwarz), April 15, 1884. These bear the label "Aphalara ilicis 

 Ashmead." This is an entirely different insect from that described 

 by myseli recently from Florida (Crawford 'lie: 629,632), and called 

 PsijUopa fioiidensis first and then corrected to Psyllopa ilicis. Judg- 

 ing from Ashmead's description of the nymph, I am inclined to 

 believe that the latter is correct, while the present species, of Pauro-
