48 INSECTS NOXIOUS TO AGRICULTURE. 
Adult female orange-red in colour, peg-top shaped; the 
abdominal segment very small as compared with the rest of the 
body, and the two next segments overlap it. Abdomen ending 
in two conspicuous, prominent, median lobes, and at each side 
of them two semi-circular depressions: several branched and 
serrated hairs in the region of these lobes. There are no groups 
of spinnerets. There is no wide depression of the edge between 
the median lobes. 
Adult male unknown. 
Habitat — On Santalum cunninghamii (Maire), Te Aute, 
Hawke’s Bay; and on pear, plum, and other fruit-trees at 
Whangarei, having probably spread from native plants. 
The carmated male puparium distinguishes this species from 
Aspidiotus. The absence of spinnerets is curious.
