b'\ 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. aeaeise -decurrentis Froggatt (’01: 248). 
d\ Genal cones short, broad at base, acutely pointed; antennae 
moderately short; legs short; wings less than twice as long as 
broad. On Capparis mitchelli. (Australia.) 
P. capparis Froggatt (’01: 250). 
c 2 . Thorax dark brown, mottled with dull yellow; forceps short; genal 
cones large, moderately long, pointed; antenna} 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; antennse 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. crcnata 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; antennse 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-j-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 leprcsa sp. nov. Plate III, fig. 8. 
Length of body, 2 millimeters; forewing, 2.9; antennse, 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.
