Rather broadly oval, convex, feebly shining. 

 Dark reddish-brown to i>ioeous. the head and 

 thorax sometimes almost black; antenna* and 

 tibia> usually paler, the former one-halt' the 

 length of Iiody. Thorax nearly twice as wide 

 as long, sides rounded on basal half, converging 

 toward apex, which is two-thirds as wide as 

 base; disk finely and densely punctate. Elytra 

 at middle one-fourth wider than thorax; surface 

 finely and sparsely but distinctly punctate, each 

 with two strife plainly visible only on apical half 

 near the suture. Length 5-6.5 nun. (Fig. 567.) 



Throughout the State ; much more com- 

 mon in the northern counties, where it 

 occurs aboundantly on hucldeberry and other shrubs along tilt- 

 borders of marshes. May 11-August 15. The last joint of the max-

 and legs paler; pubescence line, short, yellowish, rather dense. Head small, 

 less than half the width of thorax, finely and densely punctate. Antenna-

 third, the latter a little longer than fourth. Thorax twice as wide as long. 

 strongly narrowed from base to apex; sides evenly rounded, base Insinuate, 

 hind angles rectangular; surface finely and densely punctate and with a 

 fine impressed median line on basal third. Elytra at base but slightly

 Prosternum densely and roughly punctate ; abdomen finely and rather close- 

 ly punctate. Length 7 mm.
