by marginal prominences. Squames very delicate and inconspicuous, the two 

 immediately following the second lateral lobe irregularly fimbriate and considerably 

 longer and broader than the remainder, which are almost spiniform. There are five 

 pairs of small but well-defined claviform paraphyses, situated in the spaces between 

 the lobes. Anal orifice small, at rather less than one-third of the distance from the 

 extremity to the base of the pygidium. Two series of oval dorsal pores on each side, 

 running diagonally from the margin between the second and third lateral lobes. 

 Numerous long tubular glands open on to the extreme margin. Length 0-5 to 0-9 mm. 

 On twigs of Eucalyptus miniata, Darwin, N.T. (Hill, 22). 



Aspidiotus (Aonidiella) subcuticularis, sp. nov. 



Female puparium completely buried beneath the cuticle of the leaf, the reddish- 

 brown larval exuviae partially exposed. The rest of the puparium is closely adherent 

 to and di£&cult to separate from the superimposed cuticle. Its presence is indicated 

 by very inconspicuous blister-like swellings on the surface of the leaf. These vesicles 

 have a diameter of from 2-0 to 2-5 mm. Nymphal pellicle with a denser median 

 area. 



Male puparium slipper-shaped, exposed, but sunk in a shallow pit, or surrounded 

 by a slight tumescence of the tissues. Exuviae thinly covered with whitish secretion, 

 with a raised white ring and central boss, and surrounded by a narrow dark brown 

 zone. The puparium is extended posteriorly by a paler reddish-brown appendix. 

 Length approximately 1 mm. 



Fig. 2. Aspidiotus subcuticularis, sp. n. ; pygidium of adult ?, X 280. 



Adult female circular or broadly oval, the posterior extremity somewhat pointed. 

 Eudimentary antennae wdth a single longish stout seta. No parastigmatic pores. 

 Pygidium (fig. 2) deltoid, the sides converging evenly to the pointed extremity. 

 Median lobes large and broad, closely approximated ; so deeply indented on the 

 outer edge as to appear almost duplex. A small conical lateral lobe on each side, 

 situated close to the median lobes. Both median and lateral lobes with a translucent 

 marginal area. Squames small, slender and inconspicuous — two between the median
