 pronotum. is twice as wide as long with the sides feebly convex. Mesonotuni 

 large, almost circular, though very slightly wider in front than behind. 

 Parapsidal furrows deep, longer than half the mesonotum. Scutellaria broader 

 than long, elliptical, with a wide suture separating it from the epinotum. It is 

 smooth and shining. Epiuotum transversely striate and twice as broad as 

 long. The node is finer than that of the major, concave on top. In profile the 

 mesonotum is higher than the pronotum with a feebly convex dorsum. The 

 scutellum is lower than the mesonotum, while the epinotum is convex with a 

 declivity concave, and much steeper than that of the major. The wings are 

 almost colourless with the pterostigma light brown.
