Mesonotum with a central triangular linear fascia, on each side of which is an irregular and inwardly notched fascia, and the basal cruciform elevation, pale castaneous. Abdomen black, the lateral margins fringed with pale castaneous pile. Body beneath very pale castaneous; the face, anterior margin of the head between face and eyes, and basal abdominal patch, black. Anterior legs black, the femera streaked with pale castaneous; intermediate legs with the femora black streaked with pale castaneous, the tibis pale castaneous with their bases and apices black; posterior legs pale castaneous, the bases and apices of femora and tibiae black.
