Transv. Mus., xvii, 1936.) This striking and handsome species cannot be confused with any other South African species except basalis. Its entirely pale reddish or reddish brown body and legs on which only two or three narrowish thoracic stripes, the narrow base of scutellum and a row of triangular, discal patches on abdomen above, or in some ?$ also narrowish, transverse, basal, tergal and sternal bands are black, readily distinguish it from other species. The characteristic wing-pattern in which the pale yellowish brow
