 punctured, with the apex acute, and more or less distinctly chan- 

 nelled above. Coriaceous portion of the elytra dark chestnut, 

 finely and thickly punctured, with the nervures bright yellow ; 

 membrane dark brown, brassy, shining. Margins of the abdo- 

 men green, with a minute brown spine at the posterior angle of 

 each segment; apical spines black. Abdomen beneath bright 

 yellow, smooth, shining and impunctate, with the sides tinged 

 with green ; the sutures, a short transverse line near each of the 

 stigmata, a more or less distinct longitudinal central line, and a 

 zigzag line down each side within the stigmata, brown. Breast of
