fourth, behind which is a short transverse row of recumbent 
white hairs near suture, balance of surface sparsely clothed with 
fine inconspicuous yellow hairs, becoming darker and slenderer 
toward apex. Abdomen strongly punctate and finely rugose. 
Length, 4 millimeters; width, 1.5. 
Described from a unique specimen from Butuan, Mindanao 
(Baker). 
This species differs from all the other species examined by 
its head being strongly gibbose on the vertex and the epistoma 
very narrow between the eyes, which are nearly contiguous. 
Sambus bakeri sp. nov. 
Rather robust, uniformly cupreous, except head which is bril- 
liant reddish purple; each elytron with a large, oblong, lateral 
spot of a beautiful reddish purple color ; beneath cupreous, with a 
slight purplish reflection, sparsely clothed with short white hairs. 
Head deeply grooved, the groove becoming less distinct on the 
front, slightly, transversely rugose, sparsely, finely punctate and 
clothed with pale yellow pubescence, becoming denser and longer 
on the occiput; antennze coppery, reaching to middle of prono- 
tum; clypeal suture distinct; epistoma wide, transverse between 
antenne. Pronotum much wider than long, distinctly 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 strongly bisinuate, with 
the median lobe rather abruptly rounded in front of scutellum; 
lateral carina slightly arcuate, reaching perpendicularly from 
theeposterior angles to apical fourth; disk convex anteriorly, 
broadly concave posteriorly, with a rather deep depression inside 
of lateral carina reaching from base to median part; surface 
strongly punctate and concentrically rugose, densely clothed 
with long, yellowish, recumbent pubescence. Scutellum large, 
triangular; surface finely reticulate. Elytra narrower at base 
than middle of pronotum, rather convex; sides nearly parallel 
to middle, strongly expanded at posterior third, then arcuately 
attenuate to tips, which are conjointly, broadly rounded and 
finely dentate; surface finely imbricate, with a shallow depression 
extending obliquely from base to suture at basal fourth, an 
another near suture at apical fifth; a semioblong spot of brilliant 
reddish purple along lateral margin of each elytron, extending 
from humeral angle to apical third and internally to the median 
part and clothed with inconspicuous, fine black hairs, rest of sur- 
face of a uniformly bright coppery color and densely clothed with
