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 13 in.; width across expanded 

 wings, about Jin. Eyes large, prominent, facetted. Antennae 

 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- 

 like ; bearing four curling setae. Abdomen distinctly segmented, 

 each segment bearing many fine short hairs and several small 

 circular marks. Abdominal spike short, broad, bi valvular ; 

 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 jn open country, 

 Otago, Nelson, Canterbury, Wellington. For the second stage 

 the stems and roots of Muhlenbeckia adpressa (complexa ?) ; 

 Sumner Road, Lyttelton ; Evans Bay, Wellington : Rhipogonum 

 scandens (supplejack) ; Riccarton 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.
