54 INSECTS NOXIOUS TO AGRICULTUKE. 



In the female puparium and in the length of the abdominal 

 spike of the male this species resembles M. buxi, Bouche (Sig- 

 noret, loc. cit., 1868, p. 93), but differs in all other respects. 



Genus: CHIONASPIS, Signoret. 



Female puparium usually white, elongated ; pellicles at one 

 end ; generally flat. 



Male puparium white, elongated, carinated ; pellicle at one 

 end. 



Groups of spinnerets, five (in one American species, six) ; 

 rarely wanting.

Cornell Univ., 1883.

 (Plate VI., Fig. 1.) 



Female puparium dirty blackish-brown, with a grey margin ; 

 elongated. " There is a central ridge from which the sides slope 

 like the roof of a house " (Comstock) . 



Male puparium white, narrow, carinated. 



Adult female yellowish-white, elongated, segmented. Abdo- 

 men ending in six lobes, of which the two median are the 

 largest : these two are divergent. Along the edge some spines. 

 No groups of spinnerets : a few single ones. 



Adult male unknown. 



Habitat On oranges sold in the shops, imported from 

 Sydney. 



This insect, apparently an importation from America, was 

 not observed prior to 1884, and occurs as yet only sparingly, 

 mingled with A. coccineus, from which it is easily distin- 

 guished by its elongated puparium.

N.Z. Trans., Vol. XIV., 1881, p. 216. 



(Plate VI., Fig. 2.) 



Female puparium white, flat, elongated, pyriform, very thin ; 

 the pellicles rather small; length, about T V n -
