 bands. Legs with tarsi unhanded. Wing scales mottled. 



? . Head densely scaled, and with a few long bristles. The 

 curved scales are large and white in colour, except at the borders 

 of the eyes where they are smaller and of a deep golden brown. 

 The upright forked scales are numerous and all black. The flat 

 scales at the sides of the head are mostly white, though a part of 

 their ai-ea is covered with purplish dark scales. The eyes are mainly 

 silvery but have large dark black irregular patches. Clypeus shiny 

 black. Palpi densely clothed with dark scales, and a few outstand- 

 ing bristles. Proboscis covered with mixed dark and white scales, 

 giving it a mottled appearance. The basal joint of the antennae is 

 clothed with small dark hair-like bristles and a few small narrow 

 flat white scales. Mesonotum dark brown thickly clothed with deep 

 golden brown narrow curved scales, which are larger and of a white

which become lighter in colour on the apical segments. First 

 segment with a few whitish scattered scales. Small white lateral 

 apical spots on the second segment, and a pale indistinct apical 

 band consisting of a single row of scales is first noticed on the 

 third segment. It becomes more pronounced on the succeeding 

 segments, except on apical where it becomes merged into the 

 general pale coloured scales covering the whole segment. The 

 lateral spots also become more distinct on the third and succeeding 

 segments. The ventral surface of the abdomen is almost entirely 

 covered with white scales. 



Wings large, longer than the abdomen ; veins, except at the apex 

 where the scales are culex-like, clothed with mixed dark and white 

 Tasniorhynchus-like scales. The dark scales which are brown in 

 colour with a purplish reflection are the most numerous. The first 

 submarginal cell is slightly narrower though somewhat longer than
