♀ Head: sides clothed with flat white scales, interrupted by a rather narrow horizontal band of flat black ones; two large patches of flat black scales on the top, separated by a rather narrow band of narrow white scales extending from the nape on to the front; a narrow line of narrow white scales bordering the upper part of the eyes. Eyes well separated. Proboscis and palpi black. First antennal joint blackish, greypruinose. Thorax: integument blackish, except for the reddish scutellum and a small pale spot on each side at the base of the postnotum. Prothoracic lobes and the space behind them clothed with flat white scales. Scutum clothed with narrow yellowish-white and blackish scales, the former arranged in definite narrow lines as follows: a median line extending from the front margin to a little in front of the scutellum, where it forks into two; a line on each side of this extending the whole length of the scutum, enlarged a little in front of the middle and sending a branch obliquely forwards from this point to the lateral angle of the thorax; and another line forming a border to the scutum. Scutellum with narrow scales, mostly yellowishwhite, but some black ones on each side of the middle lobe. Pleurae with several patches of flat white scales. Abdomen black, above with conspicuous pure white basal lateral patches and traces of yellowish-white basal bands on all the segments; venter black, all the segments with pure white basal bands.
