Abdomen. — Sub-conical, ground colour chiefly reddish brown, 

 2nd segment with a narrow anterior, and rather wider posterior 

 band connected by a thin dorsal stripe, a rather wide irregular, 

 not well-defined black transverse band on 3rd segment, which 

 is repeated less distinctly on the following two or three segments. 

 The extreme posterior border of all the segments is reddish brown, 

 and the whole dorsum is covered lightlj^ with short, bright orange 

 hairs, which become brightest, longest and fiery red at the abdom- 

 inal tip. Belly cinereous, posterior borders of all the segments 

 orange-yellow ; whole belly covered with short orange hairs. 



Legs. — Coxse, femora and most of the tibiae reddish orange, 

 the tibiae towards the tips (especially the hind pair) and all the 

 tarsi, black. The middle femora have a few black short spines 

 below, the hind pair a row of stronger ones ; the posterior tibiae 

 are beset with black short bristles, which are longer on the hind 

 pair. The posterior tibiae have a circlet of strong black spines 

 at the tip, and the whole legs, especially the tibiae and tarsi, are 

 minutely but densely spinose. 



Wings clear ; first posterior cell closed some distance before the 

 border, the 4th longitudinal vein joining the 3rd just above the junc- 

 tion of the anterior branch of the 3rd. Two broad dark brown 

 bands. Base of wing bright orange-yellow, the colour extending 

 across the wing from the costa to (and including) the alula, and reach- 

 ing distally as far as to just enter the two basal cells. The costal 

 cell is orange-yellowish, also a spot on and over the discal cross- 

 vein, and another small spot in the centre of the upper basal cell. 



The first brown band begins in the upper basal cell, which it 

 fills, extending posteriorly, filling the 2nd basal cell and basal fourth 

 of discal cell, thence narrowing, to the hind border of the wing, 

 leaving about the distal fourth of both the anal and axillary cells 

 clear. The second band begins approximately on the costa, 

 blending with the orange colour of the costal cell, fills three-fourths 

 of the 1st submarginal and ist posterior cells, thence narrow- 

 ing somewhat, it fills nearly the distal half of the discal cell and 

 terminates distinctly clear of the posterior margin of wing, enter- 

 ing the 2nd and 3rd posterior cells. A small round quite clear 

 spot is in the extreme upper angle of the lower basal cell. A few 

 very short stiff black bristles at the base of the costa, and some 

 short close yellowish orange hairs on the margin of the alulae and 

 the orange tegulae. Halteres yellow.
