Conchotingis borneoana, new species 
Ficure 17a 
DescripTION: Large, broad, nearly rectangular in outline, brown 
with slight tinge of testaceous, body beneath dark reddish brown, 
appendages ferrugineous. Length 4.75 mm., width 2.30 mm. 
Head rather short, extended about twice the length of an eye in 
front of eyes, armed with five long spines; hind pair erect, rather 
slender; median spine erect, stoutest, and longest; anterior pair sub- 
erect, as long as hind pair; bucculae long, wide, aerolate, with ends 
meeting beneath apex of clypeus; labium extending to end of sulcus; 
laminae testaceous, composed of one row of large cells, parallel, open 
behind. Orifice of metathoracic scent glands with a short, upright 
channel on each metapleuron. Antennae moderately furnished with 
setalike, pale hairs, each of which is scarcely longer than the thickness 
of segment at point of origin. Hypocostal laminae long, uniseriate. 
Pronotum moderately convex, coarsely pitted, very wide across 
humeri, sides rather strongly converging anteriorly in front of humeri, 
tricarinate; hood fairly large, very long, tectiform, angulately project- 
ing over base of head, extending backward tectiformly almost to 
center of disc, then recurved, hooklike (fig. 17a), laterally compressed, 
not strongly inflated; median carina high, terminating anteriorly at 
base of hood near center of disc, mostly biseriate, triseriate in the 
arched part just behind hood; lateral carinae long, high, terminating 
anteriorly at calli, distinctly convexly rounded above, mostly biseri- 
ate, triseriate in highest part; paranota moderately long, much wider 
than long, turned nearly obliquely upward, with anterior and posterior 
margin rolled upward. 
Elytra very wide, rather sharply expanded basally, much longer 
than abdomen; costal area very wide, obliquely widened at base, 
mostly four areolae deep, the areolae embrowned in subbasal and 
apical bands; subcostal area rather narrow, subvertical, mostly uni- 
seriate, biseriate in widest part; discoidal area very large, extending 
beyond middle of elytra, widest beyond middle, there five or six 
aerolae deep, acutely angulate at base and apex. The outer boundary 
vein distinctly raised and evenly bowed outward; sutural area large, 
on same horizontal plane as discoidal area. Metathoracic wings 
clouded with dark fuscous, extending a little beyond tip of abdomen.
