PARLATORIA AONIDIFORMIS, sp. nov. 

 Plate LX. 



Female puparium {fi^. 3) very small ; covered almost completely by the 

 second pellicle ; a very narrow secretionary border. Pellicles fulvous ; the 

 second tinged with red, especially at posterior extremity. The second pellicle 

 has a prominent median ridge, bifurcating in front to give space to the first 

 pellicle. Under surface {Jig. 4) completely closed in by the ventral parts of the 

 second pellicle, within which the adult female and eggs remain concealed, as in 

 the genus Aonidia. Towards the posterior extremity of the ventral surface, but 

 within the margin, is a well-defined depressed area resembling the pygidium of 

 the insect, and itself bordered by a separate zone of secretionary matter. On 

 breaking away the ventral scale, the adult female, which is much smaller than 

 in the previous stage, can be seen in the anterior part of the cavity {fig. 5), 

 the hinder part being occupied by the comparatively large purplish eggs, which 

 are deposited in two rows. Total length of puparium rather less than i mm. 

 Breadth almost equal to length. Second pellicle measuring 075 by o"5o mm. 



Male puparium {fig. 2) of normal form; oblong, slightly dilated behind; 

 hinder part with median depression and faint trace of median ridge. Pellicle 

 yellowish, with semi-transparent greenish median area. Secretionary area very 

 pale fulvous or whitish. Length i mm. 



Adult female {fig. 6) with flattened expanded margin and tumescent median 

 area. Colour purplish, fading to creamy white at margin ; pygidial extremity 

 pale fulvous. No parastigmatic glands. Mouth-parts rather large. Abdominal 

 segments almost destitute of fringed processes. Pygidium {fig. 7) with six 

 prominent chitinous lobes, decreasing in size from the centre outwards. The 

 rudimentary lobe on fourth space occasionally fully developed on one or both 

 sides. Each lobe constricted at base, with sharply pointed extremity ; a single 

 notch on the inner and two notches on the outer edge. The fimbriate squames 

 unusually long and narrow, fringed at extremity only. Semi-lunar pores small 

 and inconspicuous, in connexion with narrow cylindrical ducts. Marginal 

 spines situate upon prominent tubercles in the intervals between the squames, 

 except in such intervals as are occupied by the semi-lunar pores. Basal space 

 laterally produced, with deep and irregular incisions between the squames. 

 Dorsal pores few, minute and inconspicuous. Circumgenital glands in four 

 groups ; upper laterals, 4 to 5 ; lower laterals, 5 to 6. Anal slightly posterior 

 to genital aperture. Length of extended example 0*50 mm. 



Adult male not known. 



Habitat on upper surface of leaves of Nothopegia colebrookiana ; Punda- 

 luoya. 



A minute and inconspicuous insect, somewhat abnormal in form, But a 

 careful examination shows that in every important structural character it con- 

 forms with the genus Parlatoria. The male puparium is quite typical.
