Recognition

Very fragile, head quite barrow with respect to prothorax, with strongly narrowed frons (somewhat projected beyond eye) and long antennae (with dark lines on anterior margin of scape); green-ish in life.  I've seen this species in long series, but seldom in good shape.  It is possible that there are unrecorded species in this genus.
