Antenna as in Fig. 63 View FIGURES 56 – 68 . Frons with raised, weak reticulation below level of toruli except smooth just below toruli and just below eyes, parts up to frontal suture and in angle just above frontal suture with raised, strong reticulation, and otherwise smooth above frontal suture ( Fig. 27 View FIGURES 27 – 30 ); frontal suture reaching eyes at level equal with anterior margin of anterior ocellus. Vertex with engraved, strong reticulation inside ocellar triangle, but smooth outside ocellar triangle ( Fig. 30 View FIGURES 27 – 30 ). Occipital margin rounded. Eyes with sparse, scattered hairs ( Figs 27, 30 View FIGURES 27 – 30 ).
