erayish-golden pubescence. Length 3.40 mm.; width at widest part 
of elytra 1.20 mm., across humeral angles 1.00 mm. 
Head very short, armed with five moderately long, appressed spines; 
bucculae mostly biseriate, with ends contiguous in front, not surpassing 
apex of head. Antennae moderately stout; segmental measurements: 
J, 10; IJ, 10; III, 90; 1V, wanting. Labium reaching onto metaster- 
num; laminae foliaceous, uniseriate, cordate with ends behind not 
quite meeting on metasternum. Legs moderately long, femora very 
little swollen. 
Pronotum moderately convex, punctate on disc, reticulate on 
posterior process, moderately narrowed anteriorly, tricarinate. The 
carinae quite distinct, without cells; median carina long, slightly 
higher than lateral pair; lateral carinae strongly convexly constricted 
on disc, terminating in front at calli; paranota long, wide, reflexed, 
resting flatly against pronotal surface, not extending to lateral carinae, 
six areolae deep in widest part; hood small, inflated, pyriform, truncate 
in front, extending backward between calli. Metathoracic scent 
glands with orifice and upright channel on each metapleuron.. Hypo- 
costal laminae uniseriate. 
Elytra widest across costal band, there wider than width across 
humeri of pronotum, convexly constricted on sides beyond middle, with 
sutural areas overlapping and jointly rounded behind; costal area 
moderately wide, biseriate on basal three-fifths, thence narrower and 
uniseriate, the cells (except in darkened areas) hyaline; subcostal area 
narrower than costal area, nearly vertical, biseriate; discoidal area 
large, two-thirds as long as elytra, with outer boundary vein slightly 
sinuate, acutely angulate at base and apex, widest at middle, there 
eight cells deep; sutural area on same horizontal plane as discoidal 
area, the areolae slightly larger in distal half. Metathoracic wings 
nearly as long as elytra, slightly embrowned. 
Type: Holotype (male), Laut Island, Macassar Strait, near Borneo, 
USNM 65116. 
Remarks: This species is separated from other members of the 
genus described above by the black head and disc of pronotum, widely 
convexly separated lateral carinae on pronotal disc, and the short, 
flakelike, golden pubescence.
