66 THE VICTORIAN NATURALIST. 



Male. — Puparium similar to that of female, but narrower. 

 Long, I mm. ; broad, o 50 mm. 



Adult female broadly pyriform. Pygidium bluntly pointed. 

 Pygidial lobes small and confused, almost concealed above by a 

 chitinous outgrowth of the margin ; median pair ligulate, with 

 truncate or slightly rounded extremity, separated by a space of 

 about their own width ; first lateral lobes broader than median, 

 closely followed by a stout marginal prominence simulating the 

 outer lobule often present in species of Mytilaspis and Chionaspis; 

 second lateral lobes represented by a blunt marginal prominence, 

 beyond which the margin is somewhat serrate. Squames — 

 between the lobes — rather densely chitinous. No circumgenital 

 glands. Dorsal pores rather small and inconspicuous, in the 

 usual linear series. Anal aperture moderately large, distant 

 from margin by about three times its greater diameter. Long, 

 1.05 mm. ; broad, about i mm. 



Habitat. — Shepparton, Victoria, Australia. On Styphelia 

 viigata. (Coll. C. French, No. 18.) 



(The above description has been drawn up from old and 

 densely chitinous examples. It is probable that — in early adult 

 examples— the pygidial lobes and squames would be more pro- 

 minent and conspicuous.) 



AsPiDiOTUS (Tagionia) subfervens, n. sp. (fig. 2). 



Fumale. — Puparium circular, strongly convex. Dull blackish 

 brown, thickly dusted with greyish scurfy secretion. Pellicles 

 fulvous, more or less obscured above by grey secretion. Below 

 deep chocolate-brown ; pellicles fiery red. Diameter averaging 

 1.25 mm. 



Male. — Puparium not observed. 



Adult female almost circular. Pygidium rather acutely pointed. 

 Median pygidial lobes large, prominent, convergent ; apex 

 rounded, outer edge steeply sloped and notched in the middle. 

 Lateral lobes represented only by small marginal prominences. 

 Two pairs of large, stout claviform paraphyses on each side. No 

 pectinate squames. Marginal spines moderately large. Anal 

 orifice distant from margin by about 2}^ times its greater diameter. 

 No circumgenital glands. Dorsal pores few and inconspicuous. 

 Long, I to 1. 10 mm. 



Habitat. — Victoria, Australia. On Acacia, sp. (Coll. C. 

 French, No. 24B). Received also from Mr. J. Lidgett, on 

 Fomaderris, sp. (Coll. J. Lidgett, No. 60.) 



The pygidial characters are very similar to those of A. pernic- 

 iosus ; but differ in the absence of pectinate squames, and in the 

 relatively larger size of the paraphyses. The puparium of subjer- 

 vens difters from that of 2:>eruiGiosus in its greater convexity, 

 stouter texture, and colour of pellicles.
