regularly arcuate, with the lateral margin crenulate and the 
posterior angles broadly rounded; anterior margin slightly 
bisinuate, without a distinct median lobe; base strongly bi- 
sinuate, with a broadly rounded median lobe in front of scutel- 
lum; lateral carina strongly arcuate, slightly sinuate anteriorly 
and reaching from base to near the anterior angles; disk 
strongly convex anteriorly and limited at the basal fourth by 
a broadly rounded, transverse depression ; surface rather densely 
punctate and concentrically rugose, sparsely clothed with fine, 
short, white hairs. Scutellum dark bronzy, large, triangular ; 
surface finely, transversely carinate. Elytra narrower at base 
than middle of pronotum, rather convex, with shallow basal 
depressions and a similar depression along suture near apex; 
sides parallel to apical third, then arcuately attenuate to tips, 
which are broadly, conjointly rounded and finely dentate; sur- 
face finely imbricate, rather densely clothed with short, 
inconspicuous, dark hairs of the same color as the surface, and 
marked with broader white hairs as follows: An indistinct 
elongate series along suture behind scutellum, a double 
tranverse zigzag row near middle, and a similar, more distinct 
double row at apical fourth. Abdomen rather densely punctate 
and finely crenulate. 
Length, 4 millimeters; width, 1.6. 
Described from a single specimen from Mount Maquiling, Lu- 
zon (Baker 8326). : 
Sambus lugubris Saunders. 
This species is represented by one specimen from Mount Ma- 
quiling, Luzon (Baker 8327); one from Baguio, Benguet 
Province, Luzon (Baker),; one from Dapitan, Mindanao (Baker 
8328) ; three from Davao, Mindanao (Baker) ; and a specimen 
in the United States National Museum collection labeled ‘Acc. 
No. 1130, Bur. Agri., P. I., collected by C. R. Jones,” without 
any definite locality. The Bureau of Agriculture gives Lamao, 
Bataan Province, Luzon, as the locality for the last specimen. 
This species is slightly variable in the coloration of the 
pubescence. In some specimens the transverse bands are 
composed of yellow and white hairs intermixed, while in others 
the pubescence is entirely pale yellow, with all forms of inter- 
grades, but the markings seem to be quite constant on all of 
the specimens. The males have the entire head bright green 
and the pronotum of a more bronzy color, while in the females 
the head and pronotum are of a bright reddish copper color.
