56 INSECTS NOXIOUS TO AGBICULTURE. 



Adult male unknown. 



Habitat On Dysoxylon spectabile (Kohe-kohe) , Wellington ; 

 Hawke's Bay; Auckland. 



The large white puparia of this insect do much to spoil the 

 appearance of Dysoxylon, one of the most showy-leafed plants in 

 New Zealand. 



24. CHIONASPIS MINOR, Maskell. 



N.Z. Trans., Vol. XVII., 1884, p. 33. 

 (Plate VI., Fig. 4.) 



Female puparium white, small, not more than y^in. in 

 length, usually less ; it is narrower and less pyriform than is 

 usual in the genus, and is often bent in the middle ; pellicles 

 yellow. 



Male puparium white, narrow, elongated, carinated, about 

 ^in. in length. 



Adult female elongated ; segmented, but not deeply ; 

 colour, dark-brown. Abdomen ending in six small lobes, of 

 which the two median the largest are closely contiguous. 

 Between them and the next pair is a spine ; then beyond the 

 second pair another spine, a space, and a third pair of very small 

 lobes ; after a long space there is another spine. Five groups of 

 spinnerets : uppermost group with twelve to fourteen orifices ; 

 upper pair, fourteen to seventeen ; lower pair, eighteen to 

 twenty-four : many single spinnerets. 



Adult male not known. 



Habitat On Parsonsia, Hawke's Bay on Rhipogonum scan- 

 dens (supplejack), Wellington; Canterbury; Otago. 



The small puparia and the contiguous abdominal lobes of 

 the female distinguish this species. 



Genus : POLIASPIS, Maskell ; N.Z. Trans., Vol. XII., 1879, 



p. 293. 



Female puparia elongated; pellicles at one end. Male 

 puparia narrower, elongated, pellicle at one end. Female with 

 more than five groups of spinnerets ; abdomen without fringe. 



In the kindred genus, Leucaspis, Targioni-Tozzetti (Signoret, 

 loc. cit., 1868, p. 101), the abdomen has a continuous fringe of 

 long spines, and the groups of spinnerets vary in number from 

 five to eight.
