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. 



Var. Thoracic patch and several of the spots on the elytra 

 absent. 



Length 5-6 mm. 



Hob. Nepal; Assam: Khasi 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 o 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.

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, 

 mucb liner than that on the thorax ; interstices longitudinally 

 costate at base, the costa? disappearing towards the middle, 

 pubescence long. Body beneath more shining. 



Length 6 mm.

Separable by the angulate shoulders and costate base of the

Black, clothed with fine white pubescence ; head, basal joints 

 of antennae and labrum fulvous. 



Head very finely punctured ; antennae slender, black, the basal 

 four 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.
