 ridged ; face nearly twice as long as broad, slightly ampliated and 

 rounded towards clypeus, Avhich is moderately ridged centrally 

 and laterally ; eyes placed obliquely; pronotum narrow, con vexly 

 produced between eyes, its posterior margin concave ; mesonotum 

 large, long, tricarinate, the lateral carinatious anteriorly incurved 

 and nearly meeting near anterior margin ; posterior tibiae with 

 three and sometimes with a small fourth subbasal spine ; tegmiua 

 with the basal cell emitting three veins near its upper end, claval 

 vein united to posterior claval margin near or a little beyond 

 middle, costal membrane obliquelj" transversely veined, beyond 

 middle thei*e are a number of transverse veins forming some^^"hat 

 short cells, a continuous subapical marginal line formed of trans- 

 verse veins on basal area, and above clavus four longitudinal cells, 

 the second with a transverse vein near its apex ; wings with the 

 second and third longitudinal veins emitted from a common stem,

 the venation fuscous-brown, costal membrane with three large 

 transverse piceous spots, the first near base, the other t\\o (closer

 tegmen beyond middle, the apical margin somewhat broadly and 

 irregularly and the inner margin more narrowly fuscous-brown,
