Adult female of normal form. Brnadth almost equal to length. Pvgidium 



broad and blunt. The median lobes only present ; large and prominent ; notched 

 on each side, the notch on inner edge smallest, and sometimes scarcely perceptible. 

 Two deep incisions on each side, with conspicuously thickened chitinous rims. Im- 

 mediately lateral of each incision is a sharply pointed marginal process, which takes 

 the place of the laterad lobe occurring in other species. One or two similar spiniform 

 processes shortly beyond the second incision ; the second process after the incision 

 always the most prominent. A pair of pointed squames between the median lobes, 

 and five irregularly toothed flattened squames on each side. Spines stout, with 

 thickened chitinous bases. Circumgenital glands in four groups : upper laterals 

 8 — 10, lower laterals usually 5. Dorsal pores few, in two series, not very conspicuous. 

 Three transverse chitinous bars across the base of the pygidium, and a longitudinal 

 bar on each side of the genital orifice. Anal aperture large ; distant from base of 

 lobes by about its own longer diameter. Length, 1 mm. 



The male lias not been observed in any stage. 



Amongst the Ceylonese forms that I am inclined to attribute to 

 this species are several slight variations from the type. 



The puparia, in particular, vary considerably in external appear- 

 ance, their character depending upon the nature of the plant to which 

 they are attached. Examples occurring on the smooth rind of fruits 

 (such as oranges or figs) have the scales exposed, and showing the 

 natural fulvous or yellowish colour. But any su])erficial matter on 

 the surface of the phxnt is invariably incorporated into the puparia 

 occurring on that part (^vide fig. 7, pi. xiv, " Coccidje of Ceylon "). 



In the pygidium of the adult female the chief variation is in the 

 development tf the pointed marginal processes. These are always 

 present in the same positions, but in some examples they are much 

 more strongly produced than in others. The distance separating the 

 median lobes from the first lateral cleft on each side is also subject to 

 slight variation, in some forms the thickened margin of the cleft being
