Front with short greyish pubescence, a dark, transverse band somewhat above the antennae; palpi yellow, sometimes the basal joint dark. Antennae dark brown, yellow below on the inner side. Thorax black, the humeral callus yellow, the yellow colour stretching some- what inwards on the disc; in the middle, just on the transverse furrow, there is a yellow, transverse stripe, widely interrupted in the middle, widened on the sides, and here connected with the yellow side band, and at the inner ends prolonged somewhat towards both ends, anteriorly sometimes so much as to form a narrow line, connected with the yellow anterior spot; the postalar callus yellow, this colour stretching forwardly somewhat in on the disc: on the upper margin of the pleura there is a yellow band, stretching from the humerus to the wing-root, and here much widened so that it reaches far dow^n on the pleura. Scutellum yellow, only black at the base; metapleura yellow. Thorax with short, yellowish pubescence on the disc. Abdomen black with broad, yellow side spots on the first segment, the following.
