b 2 . Forewings opaque, mottled with brown; genal cones acutely conical; 

 wings about twice as long as broad. 

 c\ Thorax ocherous, mottled with brown; forceps long and slender. 

 d 1 . Genal cones very long, acutely pointed; antennae very long; legs 

 long; wings twice as long as broad. On Acacia decurrentis. 



(Australia.) P. acaciae-decurrentis Froggatt ('01: 248). 



d\ Genal cones short, broad at base, acutely pointed; antenna; 

 moderately short; legs short; wings less than twice as long as 

 broad. On Capparis mitchelli. (Australia.) 



P. capparis Froggatt ('01: 250). 

 c\ Thorax dark brown, mottled with dull yellow; forceps short; genal 

 cones large, moderately long, pointed; antennas very short; legs 

 short. On Apophyllum anomalum. (Australia.) 



P. schizoneuroides Froggatt ('01: 253). 



Psylla fumosa sp. nov. 



Length of body, 2.3 millimeters; forewing, 3. General color 

 brown, with small lighter areas about base of wings and on pro- 

 notum; antennae brown except basal one-fourth yellowish; fore- 

 wings smoky, a little more densely browned irregularly in apical 

 portion. Body surface pubescent with short, fine hairs. 



Structurally similar to P. crenata Crawford ('17: 171), to 

 which species this is apparently closely related, differing as fol- 

 lows: Genal cones about two-thirds as long as vertex, bluntly 

 rounded at apex, somewhat divergent; antennae a little longer 

 than forewings but not quite as long as body and wings com- 

 bined; thorax more slender; wing venation similar, except cu- 

 bital petiole (M-f-Cu) only half as long as stem of cubitus 

 (Cu), while in P. crenata it is nearly three-fourths as long; 

 forewing narrower relatively. 



Male forceps stout, as long as anal valve, somewhat falcate, 

 broadest midway and arched forward, subacutely pointed; anal 

 valve moderately long, tapering from base to apex, apical third 

 slender and inclined backward. Female genital segment short, 

 about one-third as long as abdomen. 



Borneo, Sandakan {Baker), 1 male and 1 female. 



This is a close relative of Psylla crenata but is surely distinct. 

 It approaches to a confusing degree certain species of Arytaina. 



Psylla leprosa sp. nov. Plate III, fig. 8. 



Length of body, 2 millimeters; forewing, 2.9; antennae, 4.2. 

 General color lemon yellow with leprous-white areas; vertex in 

 center of pronotum, posterior edge of dorsulum, paraptera, and 

 metascutum white; legs pale; wings clear or slightly yellow, 

 antennal segments 1 and 2 pale, 3 black at extreme tip, 4 black 

 on distal third, 5 black on distal half, 6 black on distal two-thirds, 

 7 pale at base, 8 to 10 black.
