verse striz; breadth between the eyes a little smaller than the eyes toge- 
ther : face transversely striated, stronger and more oblique on the sides : 
frons longer than broad, flat at the base, more convex at the tip, the 
grooves and base of a brighter citron yellow: gens with parallel circu- 
lar streaks on the upper border which is circular, slightly sinuate be-
