SUPPLEMENTARY NOTES ON THE COCCID OF CEYLON, 1%5 
extending beyond the second pellicle. First pellicle exposed, blackish, strong- 
ly convex, subcentral. Second pellicle completely enclosing the adult insect, 
with a median convex area corresponding with the position of the larval pel- 
licle. Extremity of second pellicle with six distinct chitinous lobes followed 
by about five irregular marginal prominences,and from 3 to 5 stout spiniform 
Squames in each interlobular space. Diameter of second pellicle 1 mm. 
Diameter of complete puparium 1°25 mm, 
Male puparium similar in size and form to that of the female, but without 
the pale zone. 
Adult female (fig, 17 ) of normal form, somewhat laterally expanded. .An- 
tenna consisting of the usual tubercle, with one very small and one longish 
stout hair. Mouth parts large and conspicuous, situated close to the anterior 
margiv. Spiracles without parastigmatic glands, The body usually contains 
two large embryos, Margin of abdominal segments fringed with longish 
pointed processes, each bearing on its summit a short tooth-like spine. Pygi- 
dium ( fig, 18 ) prominent, rather sharply triangular: margin very irregular, 
It is difficult to determine which, if any, of the prominences constitute the - 
true lobes, only two of them being constant in form and position, namely a 
lareve wedge-shaped process on each side, situated about half-way between the 
. apex and the base. The anal aperture, enclosed in a conspicuous chitinous 
plate. is situated at a considerable distance above the genital opening. 
Length 0°60 mm. Breadth 0°75 mm. 
Adult male not observed, 
Habitat.—On the upper surface of leaves of the ‘Iron-wood Tree’ (Mesua 
ferrea), in the Royal Botanic Gardens, Peradeniya. The puparia of both 
sexes are intermingled and placed in a single row along cach side of the mid- 
rib of the leaf,
