depressions formed by the accumulation of minute punctures ; the 
punctuation of the thorax not so coarse ; in other respects simi!ar 
to S. equisignata.

Sternocera ruficornis, n. sp. 
S. viridis ; capite dense punctato ; thorace valde largeque punc- 
_tato; elytris S. @quisignate similibus; abdominis mar- 
ginibus anticis aureo-pubescentibus; antennis pedibusque 
testaceis, 
Green, with blue reflexions. Antenne and legs testaceous, the 
latter with a bronzy tint. Head with a slight dorsal furrow, 
closely and deeply punctured, becoming rugose between the eyes. 
Thorax at the. base once and a-half as broad as long; anterior 
margin rounded and finely ciliated, sides widening till beyond the 
middle, then nearly straight to the posterior angles; base slightly 
sinuate; disk covered with large remote punctures, becoming 
slightly larger at the sides; at the base on each side is a faint 
oblong impression. Elytra nearly twice as long as broad, sides 
rounded, widest a little behind the middle; apex with three 
spines, the exterior ones the longest; disk finely punctured, 
covered sparsely with very short white hairs, the punctures ar- 
ranged in very irregular longitudinal strize; near the posterior 
margin of each elytron are two rows of very minute pubescent 
white spots ; base with two fovee filled with white pubescence. 
Beneath punctured, the sides of the breast, the upper edge of 
the abdomen, two transverse spots on the anterior margin of the 
two middle segments (almost uniting in the middle), and a trian- 
gular spot on each side of the apical segment, covered with golden 
pubescence. 
Length 17 lines; breadth 7. 
Pachbon. 
Closely allied to S. @quisignata, from which it differs by its 
more closely punctured head; by its thorax, of which the punc- 
tures are smaller and less deep; by the margins of the ab- 
domen being covered with a golden pubescence, instead of 
having a white spot on each side; and by its yellow antennz 
and tarsi.
