Legs. The coxae of the forelegs are elongated; coxae of mid and hind legs 
with three or four spines on or near their apical margins. The femora are very 
broad, and the hind pair each have a tuft of about 60 short hairs on their 
ventral surface. 
The abdomen is broadly oval, being widest at the fourth segment. The 
tergites each have a pale transverse band (serrated on its posterior border) 
extending to, or almost to, the pleurites and with a series of about 18 to 
20 hairs on their posterior margin. On each sternite there is also a trans¬ 
verse band, which is darker and not so wide as that on the corresponding 
tergite; on each band there is an irregular series of short hairs, which on 
tergites 3 to 6 form a more or less dense patch on the sides. The band on the 
seventh sternite is interrupted in the middle, the median space being filled by 
a still darker blotch, and the same appears to be the case on the sixth sternite, 
at least the median area is also darker than the rest of the segment. On stern- 
ites 7 and 8 there is a longitudinal blotch on each side of the median line, 
extending from the middle of the seventh to the apex of the eighth. The vulva 
is broadly rounded, with a series of fine short hairs on its margin. 
The pleurites are well developed, brown in colour, with several hairs in the 
middle, and a series of longer ones and one or two small spines on their posterior 
margin.
