 eyes than to each other ; pronotum elongate, moderately laterally 

 sinuate, transverse constriction distinct, anterior lobe convex, a 

 little shorter than posterior lobe, which is deflected anteriorly, the 

 posterior lateral angles rounded, their posterior margins slightly 

 lobately produced ; scutellum a little longer than broad, with a 

 discal longitudinal carination ; corium a little more than half the

 antennae being shorter than the head ; the much longer rostrum 

 and the relative lengths of joints of same, the shorter and evenly 

 thickened posterior femora, not attenuated towards base and
