SUPPLEMEyTARY NOTES ON COCCID.E OF CEYLON. 1017 
The species is well characterized by the unusually long setiform spines 
on the margin of the pygidium. 
Chionaspis acuminata atricolor, n. var. 
It will be convenient to give a varietal name to this very constant form. 
The puparium is of a deep castaneous brown, that of the type form 
being ochreous or pale fulvous. 
On foliage of Carissa sp., Maha Illuppalama ; and on an undetermined 
plant, Kandy. Received also from Southern India, on Cnrissa and 
Tarnniindm. 
Chionaspis gynandropsidis, n. sp. (Fig. 16.) 
Fig. 16 — Chionaspis yynandvopsidis. (a, b, c). Various forms of the 
pygidial lobes, x 4o0. 
Puparium of female white, exuvise bright fulvous ; elongate, sinuous, 
broadest posteriorly. Length 2 2o mm. 
Adult female reddish yellow ; ovate, broadest across the"' abdomen. A 
small group of parastigmatic pores at the anterior spiracles only. Mesal 
lobes of pygidium varying considerably in size and form {a, b, c), large, 
divergent, partly recessed, their bases confluent, their free margins finely 
serrate ; first lateral lobes well developed, duplex, the inner lobule dilated, 
sometimes projecting beyond the mesal lobes (as at a), but usually shorter 
(6, c) ; second lateral lobes represented by broad, cristate, marginal pro- 
minences. Spiniform squames few and small. Circumgenital pores in five 
groups ; mesal group with from 8 to 10 pores ; upper laterals averaging 
24 ; lower laterals averaging 23. Oval dorsal pores conspicuous, four linear 
series on each side of the pygidium, with similar but smaller pores grouped 
on the margins of the abdominal and thoracic segments. Length 
1 to l'2o mm. 
On stems and branches of Gynandropsis sp.; Peradeniya. Very near 
subcorticalis, from which it may be distinguished by the much stronger 
development of the first lateral lobes, and by the smaller spiniform 
squames.
