taken up by the insect (on the extreme margins of the leaves), the 

 sides of the puparium are turned down, clasping the edge of the 

 leaf (see fig. 3a). Average length 2 mm. 



Male puparium (see also fig. '^a) white ; narrow elongate ; 

 transverse section lenticular ; without any trace of carinae ; 

 attached by the anterior extremity only, the rest of the scale 

 tilted up from the leaf Average length i"5 mm. 



Adult female narrow in front, widest across the abdomen, 

 increasing in width up to the segment immediately preceding the 

 pygidium. Lateral margins of abdominal segments moderately 

 produced. Pygidium (fig. 36) rounded. Median lobes very small, 

 inconspicuously dentate on free edge : first lateral lobes duplex , 

 the itmer lobule large and conspicuous, with rounded entire margin, 

 the outer lobule small and bluntly pointed, other lobes obsolete. 

 Squames spiniform, tubular, unusually long and slender. Circum- 

 genital glands in five groups: median group with from 10 to 12 

 pores, upper laterals 15 to 17, lower laterals 14 to 16. Oval dor- 

 sal pores in short diagonal series on the pygidium and on the pre- 

 ceding two segments ; other similar pores on margins of remaining 

 abdominal segments, and — occasionally — on the margins of the 

 thorax. Length i to 1*25 mm. 



On leaves of tea plant: DarjiUng (C. B. Anlram). The 

 female insects disposed along the recurved edge of the leaf ; male 

 puparia in small groups on the undersurface of the leaves. 



The species is well characterized by the exceptionally small 

 median lobes. 



Although the male puparia are not carinated, I consider that 

 the insect bears closer relationship to the genus Chionaspis than to 

 Lepidosaphes, in which it might otherwise be included.

 (PI. XXVI, fig. 4a~e; PI. XXVII, fig. 5/)- 



Puparium of female snowy white ; smooth and shining ; 

 pellicles reddish^ often partially obscured by a layer of white 

 secretion : long-ovate or pyriform, rather strongly convex in trans- 

 verse section. Average length 2*75 mm. Breadth i"4 mm. 



Male puparium not observed. 



Adult female (fig. 4a) oblong ovate, narrower in front, broadly 

 rounded behind. Anterior spiracles with a sm.all group of para- 

 stigmatic pores. Lateral area of meso-thoracic and of the first 

 three abdominal segments with numerous minute circular pores. 

 Pygidium (fig. 5/) with evenly rounded margin, broken by four con- 

 spicuous pore-bearing prominences on each side: the extremit}^ 

 (between the innermost pair of marginal pores) varying — often 

 asymmetrically — in almost every individual examined. In the 

 most symmetrical form (fig. 4^), there is a small median conical 

 point followed, successively, on each side, by a prominent lanceo- 

 late process, a broad tridentate process and an irregularly falcate
