ring apparently folded. At the extremity of the abdomen two 
long hairs springing from quadrate tubercular bases which repre- 
sent the anal tubercles. 
Adult male red or purplish in colour, wings bluish-purple 
with red nervures; length, about 4in.; width across expanded 
wings, about $in. Eyes large, prominent, facetted. Antenne 
of ten joints, each joint bearing many hairs. Feet long, 
slender, with somewhat large trochanter; on the tibia and 
tarsus a fringe of hairs as in the female. Upper digitules 
two long fine hairs; lower digitules absent. The nervure of 
the wings branches twice at least. Haltere large, inflated, sac- 
hike ; bearmg four curling sete. Abdomen distinctly segmented, 
each segment bearing many fine short hairs and several small 
circular marks. Abdominal spike short, broad, bivalvular ; 
penis protruding as a long soft white tube covered with minute 
recurved hairs. 
Habitat—For the adult female and larva the trunks of trees 
and shrubs in forests, or rocks and bushes in open country, 
Otago, Nelson, Canterbury, Wellington. For the second stage 
the stems and roots of Muhlenbeckia adpressa (complexa 2) ; 
Sumner Road, Lyttelton; Evans Bay, Wellington: Rhipogonum 
scandens (supplejack) ; Riccartcn Bush, Canterbury ; Nelson ; 
Wellington. On Muhlenbeckia the waxy tests are often largest 
and most numerous underground. Male insects sometimes found 
clustering, attached to females. 
This is a very large and peculiar species, its transformations 
and changes of secretion being abnormal. It cannot be said to 
be greatly harmful; but the odour of the second stage is 
unpleasant.
