Maskell says : "I cannot say that this species entirely agrees with the 

 usual type of Pvlvinaria, because it is by no means easy to distinguish clearly 

 the insect, so much is it surrounded by the cottony mass; yet I cannot, 

 declare that it is entirely embedded. If it were so, it would probably have 

 to be placed in the genus Signoretia, but it seems to suit Puhinaria best 

 It is another instance of a species on the border line of two genera.

Pvlvinaria thompsoni, Maskell. 

 Trans. N. Zealand Inst., vol. xxviii, p. 393, pi. xx, figs. 1-8. 1896. 

 The type specimens come from Hobart, Tasmania, where they weie col 

 lected upon the foliage of the Native Hop Bush [Dodoncea viscosa). " It 

 differs from the species found upon another species of Dodoncea in South 

 Australia in structural details in having eight-jointed antennse, larger digi- 

 tiiles of the claw, in the very small number of deimal spinnerets, in the 

 spines of the marginal depression, in size and colour." 



The adult female varies from yellow to reddish brown, general form ellip- 

 tical, flattish, margin with a row of fine hairs set rather closely together; 

 each of the marginal depressions with three or four stout club-shaped spines. 

 Length, | inch. Specimens often massed together, the twigs covered with 

 filaments. Male puparium white crystalline, angular elliptical, sides sloping, 

 top flattened. Length, ^^2^ inch.

Pvlvinaria thece, n.sp. (Fig. 8). 



Found upon the foliage of a tea plant {Thea viridis) growing in a garden at 

 Eichmond, New South Wales (Mr. C. T. Musson). 



Adult female yellowish brown ; when cleared 

 with oil of cloves it appears to be pale yellow, 

 blotched with brown; the outer margins semi- 

 transparent, marbled with yellow lines, giving 

 it a tesselated pattern. Length, J inch. Anal 

 aperture very distinct, with anal cleft rounded 

 on either side. Legs and antennae indistinct. 



Ovisac pure white, elongate, sub-cylindrical, 

 broadly rounded behind, the filaments showing 

 a fluted structure with a delicate transverse 

 wave, like a bit of merino wool. Length,
