 pronotum and under surface ; margins of pronotum, costal edge of elytra, 

 legs, buccuke and beak, yellow; apical half of posterior lobe of pronotum,

 apex, male, more evenly rounded, female; discoidal area about half as 

 long as elytra, obtusely pointed at apex, with four rows of small crowded 

 cells, which have the appearance of granules, costal area with one row 

 of large oblong cells, the black cross nervures forked ; subcostal area with 

 two rows of minute cells. Length, 2.3 — 2.5 mm. (Fig. 119, a).
