SUPPLEMENTARY NOTES ON COCCIDAL OF CEYLON. 1009 
Male puparium (c) very thin and flat ; grayish ; larval pellicle as in the 
female. 
Adult female broadly oblate, more or less crescentic in outline. Pygi- 
dium (6) narrow ; without any vestiges of pygidial lobes ; the posterior 
margin produced into long flagellate processes ; the sides (towards the 
base) narrowly cristate. Length 1 mm. 
Pygidium of nymphal pellicle (a) with two pairs of prominent lobes ; the 
median lobes parallel sided, entire ; the lateral lobes gibbous, emar- 
ginate on the outer side ; lateral margins strongly cristate. 
On the under surface of leaves of Tiirpinia pomifem. Hakgala. (Coll. 
T. Petchh 
Aonidia mesochitinosa, n. sp. (Fig. 4.) 
Fig. 4 — Aonidia mesochitinosa. Pygidium of adult $ . X 4-50. 
Puparium of female bright castaneous ; regularly ovoid, dorsal area 
slightly concave. Length 1 mm. 
Adult female sub-circular, the pygidium not projecting, its outer margin 
evenly rounded. Cepbalo-thorax with a large, circumscribed area more 
strongly chitinized. Anal orifice relatively large, at a distance from the 
posterior margin slightly greater than its longer diameter. Margin of 
abdomen with a close series of minute, bluntly conical tubercles. Margin 
of pygidium with five pairs of short but moderately broad lobes, of which 
the median are the largest, the others decreasing in size to the outer- 
most ; the three inner pairs obscurely notched on each side ; the two outer 
pairs deltoid, entire ; the fifth lobe is often missing on one or both sides. 
Squames short but relatively broad, emarginate. Spines projecting beyond 
the lobes. Length 0’6 to 0'6 mm. 
On both surfaces of foliage of Canthium montanujii. Hakgala. The 
puparia occupy distinct depressions which appear as raised spots on the 
opposite surface of the leaf,
