lobe followed by a spine. Five groups of spinnerets : lower pair with 

 12-14 orifices; upper pair with 7-10; uppermost group, 4-6. A few 

 spiny hairs are on the edge of the abdomen. 



I have not been able to hatch out an adult male, though the male 

 puparia are very numerous. 



Very abundant on Dysoxylon spectabile, often in company with Mytilaspis 

 piriformis. It seems to differ from all described species in the abdominal 

 lobes of the female. 



2. Chionaspis citri, Comstock. 



(Second Eeport of Entomol., Cornell University, U.S.A., 1883.) 

 An insect which occurs here sparingly on oranges imported from Sydney 

 belongs, I think, certainly to this species. 



3. Chionaspis minor, sp. nov. 



Female puparium white, small, not more than -^ inch 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 g\ T inch in 

 length. 



Adult female not deeply corrugated, with general form of Mytilaspis; 

 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 12-14 orifices ; upper 

 pair, 14-17 ; lower pair, 18-24 ; many single spinnerets. 



I have not seen the adult male. 



Abundant sometimes on Parsonsia ; also frequently on Rhipogonum 

 (supplejack). 



The smallness of this species and the contiguous median lobes of the 

 female abdomen sufficiently distinguish it. 



Genus Diaspis, Costa. 

 1. Diaspis boisduvalii, Signoret. 



In my paper of 1878 I reported this insect as occurring in hothouses. 

 I find that, like Asp. camellia;, it has spread out of doors, and is common on 

 several garden shrubs. I have found it abundant on the wattle. 

 2. Diaspis santali, mihi. 

 (Trans., vol. xvi., p. 122.) 



I have received from Gr. E. Alderton, Esq., of Whangarei, specimens 

 clearly belonging to this species, which in that locality seems to have spread 

 from the native trees to the orchards, and is infesting in great numbers 

 pear, plum and other fruit trees.
