d'. Wings larger, more than twice as long aa broad, broadly rounded at apex; 



pterostigma half as long as Rs orizabensis, new species. 



e-. Genal cones very short, rounded at tips; wings twice as long as broad. 



minuticona, new species. 

 PSYLLA FIBULATA, new species. 



Figs. 98, 266, 314, 482. 



Length of body 1.6 to 1.9 mm.; length of fore wing 2.6; width of 

 head 0.81. General color Hght yellowish green throughout; antennae 

 black distally. 



Vertex scarcely half as long as broad, bulging forward in front on 

 each side of median line, with a shallow fovea on each side posteriorly; 

 genal cones about as long as vertex, not strongly divergent, sub- 

 acute, pubescent. Antennae about one and a half times as long as 

 width of head. 



Thorax strongly arched. Legs rather stout; hind tibiae about as 

 long as femora, without a spur at base, or if present it is very small. 

 Wings hyaline, slightly whitish in color, about two and a half times 

 as long as broad, venation as in illustration; pterostigma long and 

 rather narrow. 



Genitalia. — Male. — Anal valve long, much longer than forceps, 

 sides subparallel, pubescence short; forceps enlarged at base, acute 

 at apex, front margin nearly straight, posterior margin deeply con- 

 cave making basal portion unusually large and distal half slender, 

 acuminate, slightly pubescent. Female. — Genital segment about as 

 long as rest of abdomen, dorsal valve distinctly longer than ventral, 

 slender at apex. 



Described from several males and females from Colorado (no data) 

 collection of C. F. Baker. 



Type.— C&t. No. 18104, U. S. Nat. Mus. 



PSYLLA SINUATA, new species. 



Figs. 267, 268, 491. 



Length of body 1.9 to 2.1 mm.; length of forewing 3.1; width of 

 head 0.89. General color greenish yellow, antennae black on distal 

 half or third. 



Similar to fibulata, but differing as follows: Body and wings larger; 

 vertex relatively a little longer; genal cones longer. Hind tibiae with 

 a minute spur at base, scarcely visible. Male forceps longer, with 

 posterior margin sinuate conspicuously, with long pubescence, apical 

 portions slender and strongly bowed inward. Female genital seg- 

 ment similar but larger and thicker. 



Described from several males and females from Pagosa Springs, 



Colorado (C. F. Baker); these bear the manuscript name of Psylla 



fibulata simulans Crawford; several from Ungava Bay, Labrador 



(L. M. Turner), July 22, seem undoubtedly to belong to this same 



species.
