18,3 Uichanco: Philippine Psyllidw 217 
metathoracic femora and tibie. Eyes light reddish brown. 
Body finely and irregularly reticulated. Body and appendages 
very sparsely and briefly pubescent. 
Head subequal in width to thorax, slightly deflected. Vertex 
about four times as broad as long, conspicuously concave 
dorsad; caudal half hidden mediad from above by prothorax. 
Ocelli small, somewhat less in diameter than antennal segment 
III; anterior subequal in diameter to posterior. Eyes subglo- 
bose, subequal in thickness to distance from lateral margin to 
median suture of vertex. Antenne about one and two-thirds 
times as long as width of head including eyes; diameter of 
segment I slightly greater than II; II about one and two-thirds 
times III; the rest of the segments distad subequal in diameter 
to III. Clypeus large and subglobose. 
Thorax robust, slightly longer than wide, about as wide as 
thick. Length of pronotum about one-fifth that of mesopre- 
scutum ; the former deflected and partly hidden laterad beneath 
latter. Mesopreescutum irregularly pentagonal, about half as 
long as wide, produced on each side into an abrupt, caudola- 
terally diverging spine. Mesoscutum subequal in length to 
mesoprescutum; about one and one-third times as wide as 
long, irregularly subcircular. Mesoscutellum less than half as 
Wide as mesoscutum, concave at cephalic margin. Metascutum 
with an erect, subconical epiphysis dorsad. Wing hyaline, 
irregularly obovate, broadly rounded at apex, slightly more than 
twice as long as wide. Pterostigma about one-third area of 
first marginal cell, brown. Hind legs slightly longer than body, 
about one and one-third times as long as middle legs; entire 
length of hind tibize sparsely armed with moderately long spines. 
Fore and middle legs subequal in length; ungues broadly curved. 
Abdomen subequal in length to thorax; length about twice 
width, and one and one-sixth times thickness. Fifth tergite 
elevated dorsocaudad above level of sixth. Genital segment, to- 
gether with anal valve and genital forceps, nearly one-fourth 
total length of abdomen, strigose. Genital forceps subellip- 
soidal, slightly shorter than anal valve and subequal in diameter 
to latter. Anal valve elongately subellipsoidal. 
Female._—Genitalia about two-fifths total length of abdomen, 
deflected at an angle of 80° to 120° from longitudinal axis of 
body, very sparsely pubescent. Dorsal valve subequal in diam- 
eter to ventral; length of former about one and one-fourth 
times that of latter: both acutely subconical. Ventral valve 
broadly curved subapically dorsad.
