Vertex considerably more than twice as broad as medianly long. 
Anterior border smooth, slightly upraised, and narrowly bordered with 
fuscous; dise of x irregularly corrugated, with a depression on 
side near each eye and three longitudinal striae between ocelli, whic 
are dull-pinkish. Vertex uniform olivaceous. Fore-border roundly and 
obtusely angulate. Edge between vertex and frons acute but passing 
immediately ventrad into a rounded curve. Eyes variegate, olivaceous 
and fuscous, 
топо irregularly transversely striate; a median transverse
