Adult female elongated-oval, convex, red in colour; length, 
about s5in. Body segmented, tapering rapidly to the posterior 
extremity ; the cephalic segment occupying more than half the 
length. Anal tubercles conspicuous, apparently two, but on close

short spiny hairs. Anogenital rmg imconspicuous, with eight 
fine hairs. Antenne of six short joints, tapering. Foot as if 
atrophied, the joints small and swollen ; digitules all fine hairs. 
On the body are many small conical spines, which are most 
numerous on the last two abdominal segments. 
Larva free, active, red in colour, flattish, elongated, tapering 
to the abdominal extremity; length, about -4in. Body seg-

short hairs. Antenne of six joints; feet normal. 
Adult male red, about jin. long; wings rather narrow, 
hyaline. Antenne ten-jointed, hairy. Feet normal. Abdomi-

Habitat—In crevices (and sometimes on surface) of bark of 
Hoheria angustifolia, on hills above the town of Lyttelton. About 
midsummer individuals may be found which have just completed 
their sac and have not yet become coated with the black fungus. 
The pegtop form and the four anal tubercles of this insect 
distinguish it from all others of the genus.
