1 66 Parlaioria, 



PARLATORIA CINGALA, sp. nov, 

 (Plate LIX.) 



Female puparium circular, flattish ; pale yellow {fig. 2) or brownish ochreous 

 ^fig- 7), according to the position of the scale on the under or upper surface of 

 the leaf respectively ; margin colourless, thin, and semi-transparent. Pellicles 

 overlapping ; pale yellow ; sub-marginal. Diameter I'So to 175 mm. 



Male puparium {fig. 3) white or faintly tinged with yellow ; oblong, posterior 

 half depressed, with indistinct sub-lateral ridges ; semi-transparent, the colour 

 of the pupa (brownish purple) showing indistinctly through the scale. Pellicle 

 at anterior extremity ; yellow. Length i mm. 



Adult female ( 7?^. 4) broadly rounded in front, pointed behind; breadth 

 almost equal to length ; broadest across metathorax ; median area tumescent, 

 marginal area flattened ; abdominal segments moderately distinct. Colour pale 

 yellow, pygidium and rostral parts tinged with reddish brown. Position of 

 circumgenital glands marked in the living insect by patches of white waxy 

 matter. Spiracles small and inconspicuous, the anterior pair placed far forward 

 on a level with the anterior parts of the rostrum. Parastigmatic glands con- 

 sisting of two pores only at each of the anterior spiracles. Margin of abdominal 

 segments with a fringe of prominent tubular processes like truncate spines. 

 These processes are unconnected with any spinneret ducts, but appear to be 

 perforate at extremity. Pygidium {fig. 5) with six prominent lobes at extremity, 

 all of about the same size, narrowed at base, free edge sharply and straightly 

 cut, inner edge longest. The usual rudimentary lobe on the fourth space is 

 here replaced by a very broad rounded lobe projecting only slightly beyond the 

 margin, its free edge forming an even curve. This is followed by a small spine- 

 like process and two conical marginal prominences in place of the usual fimbriate 

 squames. The base bears two conical points and three or four longish tubular 

 processes similar to those on the abdominal segments. Semi-lunar pores between 

 the lobes of normal form, but those on third and fourth spaces are more of the 

 oval type found in Chionaspis. Dorsal pores rather numerous, situate between 

 the thickened median area and the margin. A few small circular pores on 

 ventral surface. Circumgenital glands in four groups; upper laterals, 10 to 14; 

 lower laterals, 9 to 14. Anal at some distance below genital aperture. Length 

 about 075 mm. Breadth about 0*50 mm. 



Adult male not known. 



Eggs and young larvae pale yellow. 



Habitat on leaves of Flacourtia and Scolopiaj Pundaluoya ; Nuwara Eliya. 

 The scales occur on both surfaces of the leaves. Those on the upper surface 

 are brownish {fig. 7), while those on the under surface are distinctly yellow {fig. 2). 



Easily distinguishable from any other described species by the form of the 

 lobes and the tubular marginal processes on the lateral margin.
