THE JUMPING PLANT-LICE OR PSYLLIDiE OP THE NEW WOELD. 159 



PSYLLA ORIZABENSIS, new species. 



Figs. 95, 479. 



Closely related to torrida, differing as follows: Larger; body (female) 

 2.6 mm. long; forewing 3; head relatively a little broader. Vertex 

 less emarginate in front at median line. Wings longer, over two and 

 a fourth times as long as broad, rounded at apex, yellowish, venation 

 similar, but pterostigma distinctly larger. Female genital segment 

 a little longer. 



Described from one- female from Orizaba, Mexico (Crawford), 

 August 20, 1910. 



Type in author's collection. 



PSYLLA MINUTICONA, new species. 



Figs. 94, 480. 



Length of body (male) 1.7 mm.; (female) 2.1; length of forewing 

 2.2; width of head 0.68. General color greenish yellow to Ught 

 orange; antennae flavous on basal half, rest black. 



Resembling torrida, but smaller ; vertex almost straight across 

 front margin, rounded down from base toward genal cones almost as 

 in Calophija; genal cones very short and rounded, not as long as their 

 width at base, with a few rather long hairs; antennae as in torrida. 

 Wings about twice as long as broad, clear or slightly yellowed, broadly 

 rounded at apex, venation similar; pterostigma small, as in torrida. 



Genitalia. — Male. — Anal valve similar to torrida; forceps of same 

 type, flat-ovoid, about two-thirds as broad as long, with a similar 

 crotch-shaped structure between them. FemaZe.^Genital segment 

 similar, but shorter. 



Described from one male and two females from Champerico, 

 Guatemala (C. F. Baker). 



Type in author's collection. 



DOUBTFUL SPECIES. 



PSYLLA RECTICEPS Provancher. 

 Psylla recticeps Provancher '86: 305. 



This seems to be a species of ApTialara, and were it not for the fact 

 that the wing is described as acute, I would have no hesitation in 

 assigning it to that genus. The description of the wings suggests 

 Trioza. In his key to the genera, Provancher describes Psylla as 

 "head square in front, anterior margin slightly emarginate; antennae 

 nearly as long as body;" this is apparently ApTialara. DirapMa is 

 described as ''head cleft in front, forming on each side a conical pro- 

 jection" — apparently Psylla. 



It was described by Provancher as follows: 



Psylla recticeps n. sp.— Length 0.12 inch; color greenish yellow; head short, trans- 

 verse, emarginate in front, with a median impressed line and a depression on each
