Sambus gibbosus sp. nov. 
Small, rather elongate, head and pronotum bright reddish pur- 
ple, the former with the front bright green, the latter with a 
faint greenish tinge along the lateral margin; elytra coppery 
bronze and marked with irregular designs of white and pale 
yellow pubescence, the transverse zigzag band at apical fourth 
very distinct; beneath bronzy green and clothed with short white 
pubescence. 
Head broadly grooved for its entire length, strongly gibbose 
on vertex, slightly rugose and densely, finely granulate, rather 
evenly clothed with long white pubescence, the hairs becoming 
finer and sparser on occiput; antenne green, reaching to middle 
of pronotum; clypeal suture distinct; epistoma very narrow be- 
tween antennz. Pronotum much wider than long, narrower in 
front than behind; sides flattened and regularly arcuate, with the 
lateral margin crenulate; anterior margin bisinuate, with the 
median lobe broadly rounded ; base bisinuate, with a large median 
lobe in front of scutellum; lateral carina nearly straight ‘and 
perpendicular to base, reaching from posterior angles to a little 
beyond the middle; disk strongly convex anteriorly; surface 
coarsely punctate, concentrically rugose, and sparsely clothed 
with inconspicuous dark hairs on disk, the sides more densely 
clothed with long white hairs. Scutellum large, triangular, cu- 
preous, and finely, transversely carinate. Elytra narrower at 
base than middle of pronotum, rather convex; sides strongly sin- 
uate at posterior coxee, expanded at apical third, then strongly at- 
tenuate to tips, which are conjointly, broadly rounded and finely 
dentate; surface strongly imbricate, becoming less distinct pos- 
teriorly, and clothed with pubescence which is arranged as fol- 
lows: Each elytron with a small round patch of silvery white 
hairs at basal third near suture, but separated from it, a similar 
patch of pale yellow hairs behind these at the middle, a very 
distinct transverse zigzag band of similar white hairs at apical
