my species, P. acacice and P. euealypti, there are rows of figure-of-eight 

 orifices resembling those noticeable in all the species of Planchonia. 

 This being so, and the anal tubercles being certainly present, the 

 generic description would be as follows : — 



Sub-Division ACANTHOGOCCIDiE. 

 G-enus Peosopophora, Douglas. 



Adult female covered with a test, whicli is either waxy or so closely felted as to 

 appear almost homogeneous. Margin of test without fringe. Antennae of not 

 more than eight joints. Anal tubercles present, but in the species observed very 

 small. Anogenital ring with more than eight hairs. Feet usually atrophied. 

 Mentum usually monomerous. There is generally a small terminal orifice in the test. 



Male pupa covered with a test of similar material to that of the female. Adult 

 with antennae of ten joints. 



Larva naked, exhibiting anal tubercles. Antennae of six joints. 



Both of my Australian species produce beneath them depressions in the twigs 

 they inhabit ; these depressions are usually filled with empty egg-shells. How they 

 are produced I am quite unable to say. 



III. 



I hope to be able to complete, in time for the next volume of the 

 "New Zealand Transactions," a further Coccid paper, dealing with a large 

 number of species, sent to me from Australia, India, the islands of the 

 Pacific, and other countries, by Messrs. Koebele, French, Tepper, 

 Cotes, and others. These are not all new species, as I have found 

 amongst them several which, infesting hothouse plants in Europe, 

 were described by Signoret. Nor have I any which approach in 

 strangeness and complexity the extraordinary creatures reported in 

 my paper for 1891.

A THIED SPECIES OF ALEURODICUS. 

 BT T. D. A. COCKERELL, F.Z.S. 



Aleurodicus ornatus, n. sp. 

 There is a white Aleurodes quite abundant on the leaves of Qap. 

 sicum in the yard of my house in Kingston ; but the other day I 

 noticed a different species on one of the leaves, larger and marked 

 with grey. On examining some of the insects I was much interested 

 to find that they presented all the characters of Mr. Douglas's 

 genus Aleurodicus (Ent. Mo. Mag , 1892, p. 32).
