(Plate LXXXVIII.) 



Lee. geoiiietricum, Green, ' Catalogue of Coccidas,' hid. Mtts. Notes., Vol. IV. 



No. I (1896). 



Adult ? {figs. I, 2) broadly oval, sometimes almost circular ; liattish, thin, 

 very slightly convex above ; dorsal area with a median longitudinal and two 

 transverse moderately prominent carinas, and some intermediate smaller ridges 

 dividing the dorsum into polygonal spaces, of which there are four median and 

 a complete marginal series, the spaces occupied by concentrically marked 

 waxy plates. The dorsum coated with a thin colourless secretion which 

 is difficult to remove without injury to the body of the insect. Eyes prominent, 

 at some distance from margin. Margin with a fringe of overlapping flabelliform 

 hairs (,figs. 5, 6) ; the margin itself evenly crenulate, with four to five small 

 indentations between each point of attachment of the flabellce {^fig. 7). Stig- 

 matic clefts {figs. 5, 6), with from three to five spines not reaching the margin. 

 Scales of anal operculum {fig. 8) acutely pointed, base shorter than outer edge. 

 Antenna {fig. 3) with six joints ; third longest, almost as long as fourth and 

 fifth together. Legs small; tarsus as long as or longer than tibia {fig. 4). 

 Dermal cells obscure, oval, arranged in radiating series ; submarginal zone 

 with radiating darker lines {fig. 5) ; a few very minute translucent pores on the 

 median area. Length 3 to 3'5o mm. Breadth 2'25 to 275 mm. 



Male puparium {fig. 9), oblong oval, rather broader behind, convex above ; 

 colourless, glassy, transparent ; divided into eighteen distinct plates, the 

 divisions marked by opaque white lines. Margin ragged. Median area 

 obscurely marked with polj'gonal -plates as in the female. Length 2 mm. 



Pupa olivaceous yellow. 



Habitat on upper surface of leaves of Glycosmis peittafhylla. Pundaluoya.
