SUPPLEMENTARY NOTES ON THE COCGTDM 
OF CEYLON. 
BY 
E, Ernest Green, F.E.S., F.Z.S. 
Part IV . 
(^Continued from page 357 of Vol. XVI of this Journal.') 
{With 39 text figures.) 
The following notes and descriptions deal with new species of genera 
that were considered in the earlier parts of my Monograph. With the 
publication of part V, and the present paper, the list of Ceylon Coccidre 
has been brought up to date. Other species, doubtless, remain to be 
discovered by any diligent collector. I shoidd be glad to receive such 
novelties, with a view to the publication of further Supplementary Papers. 
Aspidiotus ambalangoda, n. sp. (Fig. 1.) 
Fig. 1 — Aspidiotus amhalangcda. Pygidium of adidt 5, X 450. 
Puparium of female flattish, oblong, much longer than broad, usually 
tapering to each extremity. Colour brownish black ; larval pellicle reddish, 
surrounded by a narrow pale ring ; nymphal pellicle concealed. Dimen- 
sions of fully developed example 2'25 hy 1-5 mm. 
Adult female rather strongly chitinized ; broadly rounded in front, 
pointed behind, with a well defined transverse groove between the prothor- 
acic and mesothoracic segments. No circumgenital pores. Dorsal pores 
minute and inconspicuous. Median area of pygidium more densely chiti= 
nous, with faint traces of partial tessellation. Extremity of pygidium with 
four pairs of prominent, bluntly pointed lobes each of which has a more 
or less distinct notch on the outer side ; median and first lateral lobes 
approximately equal in size ; second and third lateral lobes larger, 
widely separate ; margin beyond outer lobes strongly cristate. Margin 
without squames. Spines small and inconspicuous. Paraphyses six, 
elongate, slender, each with a circular knob at its inner extremity. 
Length 1'5 mm. 
Disposed along the mid rib, on the upper surface of leaves of an 
undetermined shrub. Ambalangoda. 
Somewhat resembling Pseudaonidia nigra Brain ; but differing in the 
absence of circumgenital pores.
