Neosambus glabrus sp. nov. 
Elongate, rather robust, attenuate posteriorly, strongly convex, 
glabrous; head green; pronotum dull green, with a violaceous 
tinge; elytra dark reddish violaceous; beneath aéneous. 
Head with the front wide, strongly convex, not gibbose on ver- 
tex, without median longitudinal groove; surface rather coarsely, 
densely punctate and vaguely strigose, feebly pubescent on the 
front; epistoma about as long as wide, anterior margin broadly, 
but not deeply, arcuately emarginate, the angles wide and extend- 
ing beneath antennal cavities; clypeal suture not distinct. 
Pronotum nearly two times as wide as long, widest at about the 
middle, narrower in front than behind; sides feebly margined 
and crenulate, strongly arcuate from apex to basal sixth, then 
nearly straight to posterior angles, which are nearly rectangular; 
anterior margin deeply emarginate, with a large, broadly rounded 
lobe at middle, the angles acute; base strongly bisinuate, with 
a large median lobe, which is truncate in front of the scutellum; 
disk strongly gibbose at middle; surface with a broad irregular 
depression along the lateral margin, which is more deeply de- 
pressed just back of the anterior margin, coarsely, tranversely 
rugose, the rugs becoming somewhat concentric on the elevated 
part. Scutellum triangular, very acute posteriorly; surface 
vaguely strigose. Elytra about equal in width to pronotum at 
base, strongly convex; humeral angles obtusely angulate; sides 
sinuate at posterior coxze, feebly expanded just back of the middle, 
then strongly, arcuately narrowed to tips, which are separately 
broadly rounded and feebly dentate; surface very strongly, 
transversely rugose, the rug becoming finer and denser toward 
apex, intervals with large elongate punctures, connected to the 
rugz posteriorly. Abdomen rather convex, glabrous, rather 
densely marked with distinct crenulate lines; prosternum densely 
scabrous; intercoxal process parallel to behind coxe, then abruptly 
narrowed to apex, which is rather obtuse, rather densely clothed 
with long white pubescence at middle; tarsi and claws black; 
tarsal lamella brownish.
