(PLATE CXXVI.) 
Planchonia delicata, Green, Ind. Mus. Notes, Vol. 1V. No. 1, p 5 (1896). 
Asterolecanium delicatum, Cockerell, Check List, p. 328 (1896). 
Test of adult female (fg. 4) flattish above, or very slightly convex ; oblong 
oval, more or less pointed behind; transparent; glassy; very pale yellow. 
Marginal fringe (ig. 5) very long, glassy, pale yellow ; consisting of an outer 
continuous series of long filaments; an inner series of shorter filaments, 
interrupted at regular intervals; and an intramarginal series of twenty-eight 
short paired curling filaments, the anterior eight pairs—on each side— 
divergent. Length (exclusive of fringe) 150 to 2°25 mm. Breadth 075 to 
1'iomm. Outer filaments of fringe approximately o15 mm. long. 
Adult female insect oblong oval; greatly contracted after deposition of 
eggs. Bright yellow or greenish yellow in life; tinged with reddish brown 
after death. Antenna consisting of a small tubercle surmounted by two or 
three stout bristles. Abdominal extremity (jig. 17) typical of the genus; 
similar to that of A. bambuse. Marginal spinnerets (/ig. 18) slightly larger 
than those of Jambuse: apparently unaccompanied by simple pores. No 
paired spinnerets on disc of dorsum. Some simple circular spinnerets on 
venter of abdomen. Length 1°25 to 1°75 mm. Breadth 0°75 to I mm. 
Male puparium (fg. 2) oblong oval; flattish; colourless or very pale 
yellow, the reddish pupa plainly visible beneath the test. A single marginal 
fringe of long paired filaments, and a scattered intramarginal series of short 
divaricating curling paired“filaments (7g. 9). Length 1:25 mm. Breadth 
0°75 mm. 
Adult male (figs. 3 and 10) reddish yellow ; apodema castaneous ; notal 
plates outlined with castaneous. Rather broad and depressed. Antennie 
(jig. 14) with first two joints short and stout, others narrow and elongated ; 
three knobbed hairs at apex of terminal (tenth) joint; all the joints with 
numerous short bristles, and six very long whip-like hairs distributed as 
follows :—two on eighth, and one on each of the fifth, seventh, ninth, and 
tenth joints. Head (fig. 11) broad; laterally tumescent. Ocelli four, the 
upper pair on anterior margin, the lower pair close together on under surface 
of head. Scutellum large, longer than broad. Genital sheath (fg. 13) long 
and pointed. Wings ample. Length (including genital sheath) 1:10 mm. 
Newly hatched larva (jig. 15) pale green. Eyes marginal, colourless, and 
indistinct. Antenne (jig. 16) six-jointed ; terminal joint with one long knobbed 
hair and three shorter simple hairs. Margin with twenty-eight 8-shaped 
spinnerets. 
Later larva (fig. 7) with a marginal series of twenty-eight pairs of strongly 
curling glassy filaments (ig. 8), the anterior sixteen divergent. 
In small groups on under surface of leaves of Aruzdinaria sp. Pundaluoya. 
Recorded also from Japan. 
Distinguishable from éambus@ by the much longer fringe and flatter test.
