 The head is distinct; the front a little convex, but hardly bulging; the 

 palpi distinct, scarcely reaching the middle of the front. The anterior 

 legs of the male are rather slender and graceful, the femur only a little

 the inferior process very short and abruptly pointed, the upper long, 

 rather stout, usually obtuse at tip, and a little curved.
