70 INSECTS NOXIOUS TO AGRICULTURE. 
of its basal tubercle. Antenne of ten joints; the first two very 
short, the rest longer and equal. On the last joint are several 
long hairs, of which three are knobbed. 
Habitat—On Brachyglottis repanda, Panax arboreun, Lepto- 
spermum scoparium (manuka), Hleocarpus dentatus (hinau) ; 
Wellington. 
The species is distinguishable by the shape and colour of 
the test and the arrangement of the spinnerets, in the adult 
female. The tests of the second stage may sometimes be taken 
for adult Ceroplastes rusci, Linn. ; but can be easily distinguished 
on examination of the enclosed insect.
