three-fourths as long as width of head; segment I slightly 
thicker than II ; II about one and one-third times as thick as III. 
Thorax not arched, about one and one-fifth times as long as 
wide. Forewing pads about three times as long as wide, 
broadly rounded apicad. Hind legs about half as long as body; 
fore and middle legs about five-sevenths as long as hind; sub- 
distal third of femora in all legs slightly curved entad; ungues 
about one and one-fourth times as long as diameter of tibiae, 
strongly curved subapicad. * 
Abdomen about one and two-fifths times as long as thorax, 
about as long as wide, irregularly subcircular from dorsal aspect, 
slightly narrowing down caudad; caudal margin truncate, with- 
out process. 
Younger nymphal instars. — Distinguishable from full-grown 
nymphs by their smaller size, brighter red eyes, and, in very 
early instars, absence of wax coating.

altitude of about 42 meters, January and March, 1917. Acces-

This species passes its preadult stages in the very common 
leaf galls on Ficus ulmifolia Lam. (Moracese) . For a description 
of the gall and some field observations on the adult insect, see 
Uichanco (’19: 545, pi. 6, fig. 1; pi. 12, figs. 1, 5, and 6). The 
gall is apparently similar to the work of an Indian species of 
Psyllidse on Ficus glomerata Roxb., as figured by H. M. 
Lefroy (’09: pi. 80, fig. 6).

Plate 2, fig. 12 ; Plate 4, fig. 35 ; Plate 5, fig. 46. 
Male. — Length of body, 0.9 to 1 millimeter; width of head, 
0.53 to 0.64; length of antennae, 0.35 to 0.4; length of fore- 
wings, 1.12 to 1.36, width, 0.53 to 0.6. Very dark reddish 
brown. A large, subtriangular, depressed, reddish orange area 
on metapleura. Yellowish brown as follows: Fore and middle 
legs; hind tibiae and tarsi; antennae, except distal segments, 
which are dark reddish brown ; mesopraescutum ; and distal third 
of anal valve. A broadly subtriangular, longitudinal, median, 
light reddish brown band, and a concolorous, broadly sublinear 
area on cephalic half of lateral margin, on mesoscutum; also 
on cephalic margin of mesoscutellum and median third of 
abdominal tergites HI and IV. Body and appendages sparsely 
and briefly pubescent.
