SUPPLEMENTARY NOTES ON COCCIDM OF CEYLON. 1013 
rior spiracles only. Pygidium with the mesal lobes relatively small, 
recessed, widely divergent, minutely serrate ; first lateral lobes relatively 
large, duplex, prominent, each lobule rounded at apex, the outer lobule as 
broad as or broader than the inner one; second lateral lobes in the form 
of broad, cristate prominences. Circumgenital pores in five groups, 
median group averaging 8, upper laterals 18, lower laterals 23. Dorsal 
pores in four conspicuous linear series, with an additional pair adjacent 
to the circumgenital pores. Length 1'5 mm. 
On foliage of undetermined tree. Heneratgoda. 
Oiaspis orientalis, n. sp. 
(Fig. 11.) 
Pupanum of female white ; 
sub-circular, flattish, rather 
thin ; exuviae central or 
slightly eccentric, very pale 
stramineoirs. Diameter 2'0 
mm. 
Male puparia white ; with a 
strong median and weak 
lateral carinae ; sometimes 
masked by a loose covering of 
woolly filaments. Length 1 
mm. 
Adult female (a) oblong ; 
sharply contracted behind 
the cephalo-thoracic area ; 
the remaining segments nar- 
rowing, successively, to the 
pygidium. Cephalo-t h o r a x 
and lateral protuberances of 
abdominal segments rather 
densely chitinized. Each 
spiracle with a small group of 
parastigmatic pores. Margin 
of pygidium (b) with the 
mesal lobes small, partlj' 
recessed, bluntly pointed, 
divergent, the inner edge 
obscurely serrate ; lateral 
lobes duplex, the first pair 
prominent, small, the two 
lobules of approximately equal 
size, their apices rounded or 
bluntly pointed ; second pair 
broader, each lobule with its 
apex at the inner side, their 
free edges serrate ; margin 
beyond the lobes strongly and deeply cristate. Circumgenital pores 
in five groups ; the mesal group averaging 18, upper laterals 32, lower 
laterals 24. Dorsal pores numerous, extending on to the free abdominal 
segments ; one or two close to the circumgenital pores, five curved linear 
series extending inwards from the margin, and four short series situated 
slightly above and overlapping the inner extremities of the longer series. 
Spiniform squames, on last abdominal segment and base of pygidium, small 
and inconspicuous. Length D2o to Dfimm.
