longer than the third; fourth much longer than the second. Thorax 
roughly and rather thinly punctured, with a transverse furrow and smooth 
space in front bordered with pale luteous on each side; disk partly pale 
Juteous; horns slightly inclined forward, a little longer than their breadth 
at the base, rounded at their tips. Scutellum slightly attenuated and 
acute, roughly punctured, finely punctured towards the tip, which is pale 
luteous. Hind angles of the apical abdominal segment forming two stout 
spines; no intermediate spines. Legs pale luteous, somewhat pubescent. 
Fore wings thickly and minutely punctured, with a broad pale luteous
