SUPPLEMENTARY NOTES ON THE COCCID4 OF CEYLON, 253 
Female puparium (fig. 21) oval: very pale yellow, transparent, revealing 
the adult insect enclosed within the large second pellicle. 
The second pellicle has an opaque yellowish-white margin, and beyond this 
the secretionary are. forms a narrow frilled border, Towards the posterior- 
extremity is a circumscribed concave patch, immediately followed by a rounded 
ridge. Both the pellicles are quite transparent ; their appearance being that . 
of a celluloid covering, through which the sublying insect is clearly dis- 
cernable, The second pellicle, removed from the puparium, (fig. 22), is pear- 
shaped, a circumscribed triangular patch at the extremity quite colourless 
and glassy. Size of second pellicle |mm. by 07) mm. Total length of 
puparium 1:12 mm, 
Male puparium of same size and form as female, but without the 
marginal zones, Pale transparent yellow: the single pellicle subcentrally 
situated, 
Adult female, after oviposition semi-circular, the abdominal segments re- 
tracted. Colour yellow. Pygidium (fig. 23) with a marginal series of large 
irregular pointed processes, their extremities often deeply cieft. The shape 
and number of these processes is variable: but one is always medially situat- 
ed, and there are usually five on each side. The lobes are represented by 
four (sometimes six) narrow chitinous bands in the spaces between the mar- 
ginal processes. There is a longish slender spine in the space on each side 
of the median process. The anal is situated considerably below the genital 
_ aperture. Length about 050mm, Breadth 0°62 mm, 
Adult male of normal form : genital sheath pointed, Feet with two-knob- 
bed hairs on tarsus and one on claw, Length, including genital sheath, 1 mm, 
Habitat :—On both surfaces of leaves of a species of Ficus, in the Botanic 
Gardens, Peradeniya. 
This little insect bears a remarkable resemblance to some species of Astero- 
lecanium, (or Planchonia), s0 much so, that I provisionally determined it as a 
member of that genus: and it was only after a microscopical examination 
that I discovered my mistake, The transparent scale, revealing the sublying 
insect occupying the anterior half, together with the submarginal zone and 
the frilled border, all aid in the deception : though one can conceive no pos- 
sible use for the resemblance. 
Genus MYTILASPIS. 
MYTILASPIS LASIANTHI, n.sp. (PI. F, fig. 24.) 
Female puparium elongate, broadest across the middle and tapering to 
either end ; moderately convex above ; margin not abruptly flattened ; with 
a cylindrical median channel and broad border below, as in gloverd and pallida, 
Hees disposed in two rows. Colour brownish-yellow to bright orange ; ex- 
amples on upper surface of leaf with the biighter tint ; margin paler, Pellicles 
straw-co:our, Length 2°50 mm, Greatest breadth slightly under 1 mm, 
Male puparium, pale straw-colour, with colourless margin, Length 1°50 mm,
