The legs have a longitudinal red-brown streak on the outer 
side of the femora of the first pair, and a blackish one on 
the inner side of those of the fourth pair, a white line also runs 
along the side of the tibie and metatarsi; the tarsi of the first 
and second pairs are white; the general colour of the legs is dull 
orange-yellow. 
The abdomen is joined to the therax by a distinct jointed pedicle ; 
it is of an oval form, broadest behind and pointed in front, and 
without any lateral transverse constriction. It is of a dull 
yellowish hue tinged with reddish ; on either side towards the hinder 
extremity is a large black spot ; along the middle of the upperside 
on the hinder half are two converging rews of small white spots, 
with some other white ones towards the fore extremity ; on each 
side also of the fore half are two broadish, but not very strongly 
defined, oblique brownish stripes, the hinder ones meeting at an 
angle in the middle and continued in the median line to the fore 
end. The genital aperture is well marked and of a very charac- 
teristic form.
