and on October 26th was found outside the ovisac. PecuUar movements 
were noticed, and although observed for half an hour no appreciable 
progress was made, but the movements looked as though a scraping" 
motion was being performed with the anterior end, the bristle-like 
antennae being utilized for the purpose. This can hardly be looked 
upon as a means of locomotion, I imagine, and as the $ was found 
about ^ inch heloiu the ovisac, I think the movements were rather due 
to the insect having fallen out. On the dorsum were a number of very 
delicate waxy filaments, but these did not seem to be attached to body. 
They were, I think, from the inner lining of the ovisac. 
Adult 2 viviparous; when alive may attain 2*6 mm. long by 1"8 mm. 
broad ; chestnut-brown in colour ; distinctly segmented. Margins appear 
thin and lighter in colour. 
In boiling KOH the insects become purplish and stain the liquid deeply. 
When cleared and mounted the dermis is clear and colourless except 
around the anal end, where it is much more chitinous, much wrinkled, 
and brown in colour. The anal ring has 6 long bristles and lies deeply 
recessed in a trough-like cavity. The anal lobes are represented by 
several stout hairs ; the circum-anal region bears many sharp, strong 
spines and gland-pores, and is finely rugose. 
The two pairs of spiracles are conspicuous, yellow, of usual size, 
shape, and position (Fig. 9a). 
Antennae of 3 segments, often appearing to have but 2, owing to the 
indistinct nature of 1. The segments are all very short, 1 being broad, 
2 narrowed, and 3 irregular^ conical, bearing several hairs (Fig. 9). 
Larva, purplish in colour, elongate, active. Antennae of 6 segments, 
of which 6 is longest, being as long as 4 -i- 5 (Fig. 96). Anal ring with 
6 bristles. Anal tubercles produced, each bearing a very long seta and 
2 shorter hairs. The setae of the anal lobes are about three times as 
long as those of the anal ring ; the shorter hairs on the lobes are of about 
the same length as the latter (Fig. 9c). 
Habitat : On roots of grass ; Daspoort, Pretoria. Collected by the 
writer, October 11, 1914. 
Material studied includes a number of ovisacs with 2 $ and young 
enclosed ; 16 larvae, and 15 $ $ cleared and mounted.

Gen. EHIZOECUS Kiinck. 
Adult $ exceptionally long and narrow. Antennae short, geniculate, 
of 5 joints, the terminal segment bearing several falciform spines as well 
as the usual hairs. Anal ring with 6 hairs. Integument with some 
3-grouped glands.
