The living insects are clustered in the leaf-sheaths, twenty to thirty 
females and many young often being found at the same node. They are 
pink or flesh-pink in colour, sparingly powdered with coarse white meal. 
Some are entirely without lateral filaments ; others possess them, but they 
are short. Caudal filaments are more commonly seen. The segmentation 
is distinct, and the posterior segments appear to be somewhat retracted, 
giving the insect a truncate appearance. 
The average size of the female is about 4 mm. long, but two specimens 
collected by C. P. Lounsbury measured 6 mm. and 6*5 mm. respectively. 
In mounted specimens the most striking characteristics are the com- 
paratively short legs and antennae, the scattered (single) gland-pores, and 
the long hairs and setae of the posterior segments. The caudal tubercles 
are not produced, but each bears a long seta, w^hich may reach 300 fi 
in length, and several shorter hairs. The 6 setae of the anal ring average 
150 fi in length. On each side of the penultimate segment there is an area 
which simulates the caudal lobe, also bearing a long seta (280 fi) and 
several shorter hairs. The presence of this second pair of setae at once 
distinguishes this insect from any other yet known in South Africa, and is 
such a prominent characteristic that I think it could not have been present 
in the material examined by Prof. Cockerell. This could be accounted 
for by the fact that in mounting specimens from spirit material the coarse 
setae are often broken away. On the other hand, I may be deahng with
