being strongly and closely punctured, by the base of the 
thorax being rounded, not transvsrse, by the apical furrow 
on the metanotum being longer, deeper and wider; and the

the scutellum and post-scutellum furrowed longitudinally.

on the sides of the metanotum and almost the apical third of 
the 24 abdominal segment, pale yellow, as are also a line,

the eye incision broadly and the upper part narrowly; the 
following. parts are ferruginous: antennæ, a line above the

third of the 2°%4, and the apices of the others broadly. Legs

tures which are weaker and closer together on the outer edges.
