Clypeus and supraclypeal area with rosy tints, mesonotum and scutellum rosy pink, the scutellum brightly colored. One specimen, Rota Island , July 1925 . I give this a name as it has a very distinctive appearance. Typical H. rotaensis, seen from in front, looks almost exactly like H. crotalariae Cockerell from New Caledonia , which however has a shining, olive-green abdomen.
