The puparia are scarcely distinguishable from those of A. rossi, but 

 the exceptionally large paraphyses and the disposition of the circum- 

 genital glands distinguish it from that or any other species of 

 Chrysomphalus, 

 Aspidiotus (Aonidiella) taprobanus, n. sp. (PI. I, fig. 10). 



9 Puparium pale, transparent, straw-colour : pellicles slightly darker, 

 Flatfish ; irregularly oval. Ventral scale thin and delicate, adhering 

 to under surface of dorsal scale in such a manner as to leave a central 

 channel. Greatest diameter 2 to 2 - 25 mm. 



$ Puparium smaller and paler : more elongate. Length 1*50 mm. 

 Adult 9 yellow. Pyriform. Pygidium (fig. 10) with six promin- 

 ent rounded floriate lobes of equal size. Squames broad and deeply 

 fimbriate : the outermost three aciculate. Paraphyses small and incon- 

 spicuous, one at inner side of base of each lobe. No circumgenital glands. 

 Pygidial characters very similar to those of A. aurantii, but ultra- lobular; 

 squames not bifid. Length 1 to 1*25 mm. Breadth about 0*75 mm. 

 Adult $ not observed. 



Habitat. — On leaves of Phyllanthus myrtifolius : usually on upper 

 surface. Peradeniya. May. 



The species differs from aurantii in the simple form of the ultra-lobular 

 squames. The derm is more delicate and never becomes densely chiti- 

 nous : nor are the pygidium and abdominal parts withdrawn into the 

 body as in aurantii. 



Aspidiotus (Targionia) PByllanthi, n. sp. (PI. I, fig. 11). 

 9 Puparium dull black, with a raised whitish disc on larval 

 pellicle : moderately convex : more or less concealed beneath the corky 

 outer bark. Diameter 1 to 1'25 mm. 



$ Puparium grayish, (a whitish bloom overlying the blackish se- 

 cret ionary area). Pellicle very dark shining brown, with a raised 

 whitish circle in centre. Length 1 mm. 



Adult 9 circular : the pygidium only slightly projecting, demarked 

 from abdomen by a curved series of irregular thickened chitinous 

 patches. No parastigmatic or circumgenital glands. Pygidium (fig. 11) 

 with eight well-defined stout emarginate lobes, each with a conspicuous 

 elongate paraphysis at its base. No pectinate squames. Dorsal pores 

 small, circular. Diameter 0*60 to 0'70 mm. 



Adult $ brownish orange: nolal plates and scutellum paler: apo- 

 dema castaneous. Form bread, depressed. Head small ■ ocelli black :
