    sub-callus black covered with grey bloom. Frontal callus glossy black, tapering to a fine point, about two-thirds the length, and its base almost as broad as the front; palpi white, ground colour black, clothed'with mixed black and white hair on the upper margin and outer edge, except the base which is clothed with fairly long white hairs. Antennae black, first and second segments clothed with moderately long black hairs, the upper edge of the second segment produced into a sharp moderately long point; terminal segment with expanded portion moderately broad, and the angle on its upper margin prominent. Thorax.—Black clothed with black appressed hairs, with a few mixed golden and white hairs at the base of the wings, a few golden ones at the base of the thorax; humeral calli with a long black fringe; pleurae slaty grey clothed with long white hairs, denser at the base of wings; scutellum, with similar ground colour to rest of thorax, clothed with black appressed hairs, with lateral border of bright golden hairs. Abdomen.—Black, except the first segment which is greyish clothed, with black appressed hairs; first segment with a patch of bright creamy hairs in the centre of the apical edge with a patch of white ones on either side towards the base, and with a broad lateral grey spot; segments two to six with a median apical white spot clothed with white hairs; segments two to four with broad lateral white spots. Venter brown clothed with black appressed hairs; all the segments, except the first, with white apical bands; segments two to five have the bands clothed with white appressed hairs; bands on sixth and seventh are clothed with black appressed hairs.

The following is Walker's description:— Nigro-cinereus, thoracis lateribus, pectore abdominisque segmentorum mar- ginibus postieis ferrugineis, antennis ferrugineis apice piceis, pedibus ferrugineis, tibiis anticis apice tarsisque piceis, tarsis anticis nigris, alis einereis.
