Length, 4 millimeters; width, 1.5. 
Described from a unique specimen from Iligan, Mindanao 
(Baker). 
Neosambus viridipennis sp. nov. 
Elongate, rather robust, attenuate posteriorly, strongly convex; 
head and pronotum bright brassy green; elytra bright bottle 
green; beneath piceous, shining and glabrous. 
Head with the front narrower than in the other species of this 
genus, strongly convex, not gibbuse on vertex, and without me- 
dian longitudinal groove; sides concave, with the front feebly 
expanded on occiput, more strongly expanded at anterior mar- 
gin; surface coarsely, densely strigose, the strigze transverse on 
the front, becoming concentric on vertex, intervals with large 
shallow punctures ; epistoma transverse, anterior margin broadly, 
but not deeply, arcuately emarginate, the angles extending be- 
neath the antennal cavities; clypeal suture transverse, elevated. 
Pronotum one-half wider than long, widest at about the middle, 
slightly narrower in front than behind; sides feebly margined and 
crenulate, strongly, arcuately rounded from apex to middle, then 
nearly parallel to posterior angles, which are nearly rectangular ; 
anterior margin arcuately emarginate, with a feeble median lobe, 
the angles acute; base bisinuate, with a large median lobe, which 
is truncate in front of the scutellum; disk broadly gibbose on 
the anterior median part; surface with a broad, deep, irregular 
depression along lateral margin, reaching from apical angles 
to the base, and a broad, transverse, concave depression along 
the posterior margin, rather finely, sparsely rugose, the intervals 
nearly smooth, with a few small punctures connected to the rugs 
posteriorly. Scutellum triangular, very acute posteriorly; sur- 
face finely strigose. Elytra as wide as pronotum at base, 
strongly convex ; humeral angles obtusely rounded; sides strongly 
sinuate at posterior coxse, broadly expanded behind middle, then 
rather obliquely narrowed to tips, which are separately, broadly 
rounded, and feebly dentate; surface rather coarsely, trans- 
versely rugose, becoming smooth posteriorly, intervals sparsely, 
coarsely punctate. Abdomen rather convex, glabrous, shining, 
sparsely and indistinctly marked with crenulate lines ; last ses- 
ment broadly emarginate at apex; prosternum finely, densely 
scabrous ; intercoxal process parallel-sided to behind coxee, then 
abruptly narrowed to the apex, which is rather acute, sparsely 
clothed with long pubescence; tarsi and claws black; tarsal 
lamellz yellowish.
