small one on the middle of the loral suture, narrow below the lorse 
but, on meeting the clypeus, suddenly expanding and extending to 
its apex ; lorse and clypeus entirely yellow, or with their lower ends 
blackened ; entire length of face distinctly greater than the width. 
Pronotum colored like the vertex on the anterior margin but shad-

on the posterior half, nearly three times as wide as long. Scutellum 
small, greenish or yellowish without markings, transverse groove
