N. viridipennis sp. nov. 
Elytra feebly expanded behind middle and of a reddish violaceous color. 
N. glabrus sp. nov. 
Neosambus cupricollis sp. nov. 
Elongate, robust and strongly convex, shining; head and 
pronotum bright cupreous, becoming brassy on front of head; 
elytra and beneath bright greenish blue, glabrous. 
Head with the front wide, strongly convex, feebly gibbose on 
the vertex, with a feeble, median, longitudinal groove on vertex 
and occiput, becoming obsolete on middle of front; surface 
strongly strigose, the strigze transverse on the front and becom- 
ing concentric on the gibbosities; intervals with large, shallow 
punctures; epistoma transverse, anterior margin broadly but 
not deeply, arcuately emarginate, the angles extending beneath 
the antennal cavities; clypeal suture transverse, elevated. Pro- 
notum one-half wider than long, widest at about the middle, 
slightly narrower in front than behind; sides feebly margined 
and crenulate, strongly arcuate from apex to basal sixth, then 
nearly straight to the 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 scutellum; disk strongly gibbose behind the middle; surface 
with a broad, irregular depression along the lateral margin, 
extending from apical sixth to base, coarsely, transversely 
rugose, except on the gibbosities, where the ruge are more or 
less concentric, intervals smooth, with elongate punctures con- 
nected posteriorly to the ruge. Scutellum triangular, very 
acute posteriorly ; surface smooth. Elytra as wide as pronotum 
at base, strongly convex; humeral angles obtusely angulate; | 
sides strongly sinuate at posterior cox, broadly expanded just 
behind the middle, then arcuately narrowed to tips, which are 
separately, broadly rounded and finely dentate; surface very 
coarsely, transversely rugose, becoming much smoother toward 
apex, intervals with coarse, elongate punctures behind the ruge. 
Abdomen rather convex, glabrous, rather densely marked with 
distinct crenulate lines; prosternum coarsely scabrous and
