SUPPLEMENTARY NOTES ON THE COCCID^E OF CEYLON. 353 



linear series. Circumgenital glands in five groups, with moderately 

 numerous orifices. Length 1 to 1*25 mm. Breadth 0*60 mm. 



Adult $ not known. 



Eggs numerous , bright yellow. 



On Strobilanthus, sp. Haputale. February. 



Allied to Ch. megaloba, from which it differs in the considerably 

 larger size, in the narrower mesal lobes, and in the presence of conspi- 

 cuous oval pores on the margins of the thorax. 



Chionaspis coronifera, n. sp. (PL K, figs. 33, 34.) 



9 puparium white, sometimes tinged with ochreous : pellicles 



reddish. Strongly convex, the sides sloping up and forming a median 



longitudinal rounded ridge, — the form probably accentuated by the 



situation of the puparium on the extreme margin of the leaf. Length 



2 mm. 



$ puparium white : distinctly tricarinate : pellicle pale yellow. 

 Length 1*50 mm. 



Adult 9 after gestation reddish : densely chitinous, with exception 

 of penultimate segment. Thoracic area strongly convex, the posterior 

 dorsal area overhanging the abdomen. Early adult not densely chiti- 

 nous, and of a paler colour. Rudimentary antennas (fig. 33) of remark- 

 able form: each consisting of a chitinous ring bearing from four to six 

 stout spines and a central longish curved stout bristle. Behind each 

 antenna is an oval translucent space. Other similar translucent spaces 

 are scattered over the cephalo-thoracic area. Margins of abdominal 

 and post-thoracic segments with numerous oval pores (obscured in the 

 more densely chitinous examples). Pygidium (fig. 34) with large 

 conspicuous oval dorsal pores, in more or less definite series. No 

 circumgenital glands. Marginal squames spiniform, stout. Lobes 

 bluntly lanceolate, small, pale and very inconspicuous : set back on the 

 ventral surface and scarcely projecting beyond the margin. Median 

 pair simple : second pair duplex : third pair apparently simple. In the 

 denser examples, the dorsal area of the pygidium has some large clear 

 oval spaces (distinct from the dorsal pores). Length 0"75 to 1-50 mm. 



Adult $ not observed. 



On leaves of undetermined tree. Galgammuwa, N. W. P. August. 



The female puparia are attached to the extreme margins of the 

 leaves. Male puparia grouped on under surface.
