14 THE WOMBAT. 



Aspidiotusm yoporii, sp. nov. 



Female puparium circular, slightly convex, dark brown 

 in colour, of a lighter tinge towards the edges. In some cases 

 the colour is almost black, and forms quite conspicuous objects 

 on the green leaves of the food-plant. Pellicles yellowish, 

 forming a slight depression. Average diameter about ^in. 



Male puparium somewhat elongated ; light brown in 

 colour; pellicles at one end. Average length A in. 



Adult female peg-top shape ; abdomen ending in six 

 triangular lobes ; several groups of spinnerets showing respec- 

 tively eight and ten orifices. Ground colour dark brown. 

 Average length to in. Type in the Gordon Technical College 

 Museum. 



Adult male unknown. 



Habitat — On Myoporum deserti at Myrniong, Victoria. 

 Specimens collected by Mr. H. Lidgett. 



This species seems to approach Aspidiotus setiger, Mask. 

 Trans. N.Z. Inst. p. 298., 1896., in the size and form of the 

 puparium, but the position of the pellicles is already sufficient 

 to distinguish it, and the appearance of only eight orifices in 

 the " spinnerets groups " is in itself sufficient to separate it 

 from that species which occurs, by the way, in Japan at 

 Yokohama on Quercus, whereas A. myoporii occurs on a totally 

 different genus of plants as well as being indigenous to 

 Australia. From A. ros:i it differs in the shining texture of 

 the puparium, and in the position of the larval pellicles, and 

 it is a larger species. I can find no trace of any previous 

 record of a species of Aspidiotus occurring on Myoporum. It 

 is, no doubt, a clearly distinct species. 



Genus Poliaspis, Mask.

 ending in two lobes. Many single spinnerets and several 

 " groups." No sign of any abdominal fringe. Ground colour 

 yellowish brown Average length before gestation Aj in.
