of base, a common sutural spot below the latter, another oblong- 
ovate on the sides behind the middle and a small spot external 
to the humeral callus, black and shining. 
Yar. Thoracic patch and several of the spots on the elytra 
absent. 
Length 5-6 mm. 
Hah. Nepal; Assam: Ivhasi Hills; Burma; Andamans; Sumatra; 
Northern China. 
This species seems to vary a good deal in regard to the black 
markings ; in some specimens the sides of the breast and abdomen 
have black spots, in others these are absent ; the sides of the thorax 
have likewise sometimes black markings. A specimen from the 
Andamans in my collection is of more elongate shape and the 
markings are opaque, but I cannot find any other differences.

p. 906. 
Beddish-fulvous, clothed with white pubescence. 
Head strongly and closely punctured, with central groove ; man- 
dibles black, apex fulvous ; antennae fulvous, apical joints slightly 
thickened. Thorax about half as broad again as long, very closely 
and much more strongly punctured than the head, interstices 
slightly rugose, pubescent. Elytra with the shoulders prominent 
and angulate, a depression below the base ; puncturation very close, 
much finer than that on the thorax ; interstices longitudinally 
costate at base, the costae disappearing towards the middle, 
pubescence long. Body beneath more shining. 
Length 6 mm.

Separable by the angulate shoulders and costate base of the

705. Aoria fulvifrons, Jac. Ann. Mus. Civ. Genova, xxxii, 1892, p. 905. 
Black, clothed with fine white pubescence ; head, basal joints 
of antennae and labrum fulvous. 
Head very finely punctured ; antennae slender, black, the basal 
tour joints fulvous, the fourth joint longer than the third. Thorax 
of usual shape, widened towards the middle, very closely punctured 
and closely covered with whitish hairs. Elytra wider at the base 
than the thorax, the shoulders rather angulate but not very 
prominent, the puncturation fine and very close, the interstices 
finely transversely wrinkled, very closely covered with rather long- 
white pubescence. Underside and legs black, clothed with white 
pubescence. 
Length 4 mm.

Smaller than A. nigrita, and distinguished by the colour of the
