ASTEROLECANIUM CORONATU\M, sf. ov. 
(PLATE CXXIV.) 
Test of adult female (jigs. 2-4) very broadly oval, sometimes almost 
circular, with a short tubular upturned caudal extension (jig. 3). Strongly 
convex above, with two conspicuous foveze on the dorsum, the depressed areas 
divided by a rounded ridge which is expanded and elevated behind; sides 
rising steeply from the margin, surmounted by a series of fourteen longish 
radiating pointed processes, which, in older and worn examples, are often 
incomplete or reduced to rounded prominences. Margin with a fringe of short 
glassy filaments, more or less concealed by a thick deposit of opaque white 
waxy matter. Colour fulvous, opaque and minutely granular in fresh examples, 
semi-translucent and smooth in worn examples ; massed examples (fg. 1) with 
a distinctly pinkish tinge. Lengtho’$ mm. Breadth 06 mm. 
Male puparium (fg. 5) rounded in front, broadest at a point about one-third 
from anterior extremity, tapering evenly behind. Dorsum with two conspicuous 
foveze extending to the posterior extremity, giving a tricarinate appearance to 
the insect. Colour pale stramineous. Lengtho5 mm. Breadth 0-3 mm. 
Adult female (fg. 6) of the same form as the test: the body broadly oval, 
with a stout caudal extension. The whole dorsum with numerous small 
irregularly disposed 8-shaped glands, amongst which are a few of a much 
larger size (zg. 8), forming an irregular sub-lateral series. Margin with a close 
series of small 8-shaped glands and a ventro-marginal series of small, simple 
circular pores (jig. 9). Posterior extremity (fg. 7) without caudal setz, but 
with two small marginal spines on each side. Anal ring with six stout hairs 
scarcely projecting beyond the margin. Dorsal lip of anal aperture broad, 
extending to hinder margin, the sides slightly recurved. From four to six small 
circular pores on each side, just within the margin. Lengtho'7 mm. Breadth 
o'5 mm. 
Densely clustered at the base of the stems of the ‘Giant Bamboos’ (Dezdro- 
calamus giganteus and Gigantochloa aspera). Peradeniya.
