ASTEROLECANIUM CERIFERUM, sf. nov. 
(PLATE CXXIII.) 
Test of adult female (gs. 3, 4) elongate, narrow ; lateral margins approxi- 
mately parallel, extremities rounded. Dorsum moderately convex, the posterior 
third depressed and slightly concave ; sides and front almost perpendicular, 
slightly sloping inwards, demarked from the dorsum by the angular marginal 
line ; posterior extremity free, the under parts sloping sharply inwards so that, 
in profile (jig. 4), it appears to be sharply pointed. Ventral surface convex, 
owing to a marked depression in the leaf beneath the insect. Margin with 
straight stout glassy colourless filaments, rather widely spaced, longest at the 
two extremities. Sides thickly coated with opaque, white, mealy secreticn, 
which extends slightly over the margin, concealing the bases of the glassy 
filaments. Colour, during life, pale lemon yellow, darkening afterwards to 
ochreous. Length 1°5 mm. Breadth o'5 mm. 
Male puparium (jig. 6) elongate, narrow ; bluntly rounded in front, pointed 
behind ; a more or less distinct rounded median longitudinal ridge; anterior 
half convex, posterior nalf depressed and concave. Colour very pale lemon 
yellow, the sides more or less coated with opaque white secretion. In fresh 
examples there is probably a fringe of glassy filaments, as in the female ; but 
in all my examples the fringe has disappeared. Length 1°25 mm. Breadth 
0°28 mm. 
Adult female bright lemon yellow, darkening after death. Of approximately 
the same form as the female test; slightly narrowed towards the posterior 
extremity. Antenne rather prominent; sub-globular, each with several curved 
hairs at its extremity. Spiracles large and conspicuous, each with a dense 
group of small circular glands guarding its aperture. Posterior extremity 
(jig. 10) without lobes or setee ; anal ring apparently hairless, at the base of a 
remarkable funnel-shaped chitinous tube. Marginal 8-shaped glands widely 
and irregularly spaced ; varying in size, largest at the two extremities of the 
body (jigs. 8 and 10), smallest on the median area (ig. 9), the difference in size 
corresponding with the difference in length of the marginal filaments of the test, 
their longer axis usually set at a considerable angle with respect to the marginal 
line. Smaller supplementary paired glands scattered over the dorsum, more 
especially towards the margins, where they might almost be regarded as a 
secondary marginal series. Simple circular pores very numerous, more densely 
clustered towards the margin of the body (fg. 9). Length of extended insect 
approximately 1 mm. Breadth 0°35 mm. 
Adult male unknown. 
Embryonic larva (fg. 7) with eleven 8-shaped glands on each side, set more 
or less transversely. 
On leaves of a species of bamboo, the insects resting in shallow pits on the 
under surface of the leaf, these hollows appearing on the upper surface as raised
