Described from fourteen males and eight females. 
Cotypes. — No. 18178, in College of Agriculture, University 
of the Philippines. 
The present variety is distinguished from the species prin- 
cipally by its strongly deflected head, brown pterostigma, and 
darker brown abdomen, which is concolorous with notum. 
Nymphs ( living specimens). — Very light whitish yellow. 
Black as follows: Apical and subapical antennal segments; 
distal portions of the rest of antennal segments proximad. 
Eyes red. Tibiae and tarsi reddish white. Body and append- 
ages sparsely covered with long hairs and an irregular thin 
coating of wax. A slender, fluffy, waxy filament, usually longer 
than body, joined to each side of subapical abdominal tergite. 
The species, likewise, has been reported to produce similar 
waxy secretions (Crawford T5:260), and it is said to be at- 
tended by ants. 
Nymph ( apparently full-grown; mounted in balsam) . — Length 
of body, 1.84 millimeters; width of head, including eyes, 0.6; 
length of forewing pads, 0.64, width, 0.2; length of abdomen, 
1.04, width, 0.59; length of larger caudolateral wax glands, 
0.2, thickness, 0.09. Light yellow. Eyes red. Brown as 
follows: Ungues; terminal and subterminal antennal segments. 
Body and appendages very sparsely covered with moderately 
long hairs. 
Head slightly narrower than thorax, obtuse at cephalic mar- 
gin. Vertex about one and one-fourth times as long as wide. 
Eyes subhemispherical, about four-sevenths as thick as width 
of vertex. Two small, irregularly diffuse areas situated meso- 
caudad from eyes and concolorous with latter, presumably 
representing posterior ocelli. Antennae about twice as long as 
width of head including eyes; basal two segments shorter and 
thicker than the rest, as in adult. 
Thorax about one and one-eighth times as long as wide, 
suburiiform in width throughout. Hind legs about one and 
one-fifth times as long as middle ; fore and middle legs subequal in 
length; ungues curved apicad. 
Abdomen about one and six-sevenths times as long as thorax ; 
width about half the length; uniform in width from thorax to 
beginning of caudolateral wax glands ; obtusely angular caudad, 
terminating in a small, subcylindrical, caudal segment, about 
twice as wide as long and about two-sevenths as wide as larger 
portion of abdomen ; two short, bristlelike hairs on each side of 
caudal segment ectodistad. Larger pair of subreniform wax
