SUPPLEMENTARY NOTES ON THE OOCGIDM OF CEYLON. 349 



A minute and obscure species, occurring in small groups on under- 

 surface of leaves of Mesua ferrea. Peradeniya. February. 



Placed provisionally in the genus Syngenaspis : but possibly requiring 

 a new genus for its reception. The general characters of the pygidium 

 are suggestive of Parlatoria from which it differs in the absence 

 of circumgenital glands. The remarkable marginal of tubular 

 spines appear to be homologous with those found in some species of 

 Fiorinia.

9 Puparium broadly oval: flattish. Brownish-ochreous : opaque 

 or semidiaphanous. Pellicles overlapping ; situated at anterior extre- 

 mity; occupying about half the expanse of the puparium. Length 

 1*50 mm. 



$ Puparium narrow, elongate. Pellicle yellow, with broad blackish 

 or greenish median fascia. Secretionary area pale ochreous. Length 

 1 mm. 



Adult $ pale pinkish-purple. Broadly oval before gestation : shrink- 

 ing after oviposition, until the breadth often exceeds the length. 

 Pygidium broadly rounded : margin (fig. 26) with six prominent, 

 conical, slightly floriate lobes. Squames broad and deeply fimbriate, 

 extending along margin of abdominal segments. Broad conspicuous 

 lunate pores in the interspaces between the lobes and at close intervals 

 along the margin beyond. Circumgenital glands in four groups with 

 few orifices— 5 to 7 in each group, upper group usually with the larger 

 number. Length 0*50 to 0*75 mm. 



Adult $ not observed. 



On upper surface of leaves of an orchid ( Cymbidium bicolor). Kand v. 

 December. Also on both surfaces of a cultivated orchid at Watagoda. 

 Examples on the undersurface (which in this plant is the more exposed) 

 have the puparium darker and more opaque, whilst those on the other 

 surface are semi-transparent and paler. 



The species is almost universally distributed, being recorded from 

 nearly every part of the world. In temperate regions it is found only 

 upon plants under glass.
