NEW LACEBUGS—DRAKE AND RUHOFF 135 
reddish fuscous. Antennae brownish, with first two segments black 
fuscous and fourth dark fuscous. Legs brown, with femora mostly 
dark fuscous and tips of tarsi dark. Length 2.90 mm., width 0.88 mm, 
Head very short, slightly produced in front of eyes, armed with a 
pair of short, stout, blunt, occipital spines, other cephalic spines want- 
ing; eyes large, transverse; antenniferous tubercles short, bluntly 
rounded in front, not spiniform. Antennae moderately long, incon- 
spicuously pubescent, rather slender; segmental measurements: I, 18; 
II, 9; III, 76; IV, 38. Labium extending to base of mesosternum; 
buccal laminae wide, areolate, with ends meeting anteriorly; laminae 
of sternal sulcus not very broad, uniseriate, widely separated, parallel, 
closed behind by a transverse ridge. Ostiole and ostiolar canal of 
metathoracic scent glands with an upright sulcus on each meta- 
pleuron. Hypocostal lamina narrow, uniseriate. 
Pronotum rather strongly convex across humeral angles, reticu- 
lately punctate, tricarinate; median carina very distinct, percurrent, 
with two or three small areolae between calli;lateral carinae distinct and 
parallel on hind pronotal process, less elevated and concave within 
on pronotal disc; calli deeply impressed, impunctate; collum wide, 
truncate in front; with transverse rows of areolae; paranota cariniform, 
slightly wider opposite call. 
Elytra parallel sided, extending beyond apex of abdomen; costal 
area very harrow, uniseriate, not clearly separated (except in wider 
part opposite apex of discoidal area) from subcostal area, with tiny 
areolae; subcostal area obliquely upright, mostly biseriate; discoidal 
area extending a little beyond middle of elytra, acutely angulate at 
both base and apex, four areolae deep opposite apex of posterior 
process of pronotum; sutural area on same horizontal level as dis- 
coidal area, with areolae distinctly larger than in other elytral divi- 
sions. Hind pair of wings extending beyond apex of abdomen, 
densely clouded with dark fuscous. 
Typz: Holotype (male), Sandakan, Borneo, C. F. Baker, USNM 
65117. 
Remarks: This species is most closely related to P. wlustris Drake 
and Poor, but is readily separated from it by its shorter body, darker 
color, and distinctly narrower costal area. The lateral carinae are 
also fairly distinct on the pronotal disc. Both species are customarily 
found with snowy-white excretions (as depicted in fig. 9, the holotype).
