Large stridular area on femur. Female palae short cultrate, femur also apparently with a strid-ular area. No terminal palar spine in either sex. Male vertex tumid, face flat, hardly foveate, female face convex. Meta-thoracic wings aborted in both sexes. Male asymmetry and strigil dextral ; fifth tergite entire, sixth divided.
