NEOLECANIUM CRUSTULIFORME, sf. nov. 
(PLATE XCIV.) 
Adult female (figs. 1, 2, 3) oval, sometimes broadly so; moderately convex 
above; margin greatly thickened and slightly upturned, elevated by a sub- 
marginal ventral densely chitinous wall ; disc finely, margin coarsely granulate ; 
a short median carina at anterior extremity, and a double carina connecting the 
anal operculum with the posterior margin. Colour bright castaneous, the disc 
marked with an irregular black loop; margin dark reddish brown; anal 
operculum dark castaneous. The structure of the limbs and marginal fringe is 
obscured—in the older examples—by the very densely chitinous derm, and can 
be studied satisfactorily only in the early adult insect. Antenna (jg. 4) six- 
jointed, the third longer than the terminal three together ; terminal joints much 
wrinkled. Legs rather slender; tibia scarcely longer than tarsus ; foot with 
four digitules, the unguals small and narrowly dilated. Valves of anal oper- 
culum (jg. 5) with base and outer edge forming an even curve; moderately 
pointed at apex. Margin (/zg. 6) with a close series of stout sharply-pointed 
spines; a single slightly larger spine marking the stigmatic area; no con- 
spicuous stigmatic cleft. The subsequent incrassation of the margin overlaps 
and conceals the fringe of spines. Derm crowded with large irregularly oval 
or pyriform cells (jig. 7), each with a smaller and more regularly oval paler 
_ inner areola which lies at a lower stratum in the derm; many minute translucent 
pores piercing the surface; a few larger glandular pores distributed amongst 
the dermal cells. Length 275 to3 mm. Breadth 1°75 to 2 mm. 
Male unknown, in any stage. 
On small branches of undetermined tree; Chilaw. 
Superficially resembling a Lecanzwm, but differing in the spinous margin and 
the submarginal ventral wall. The name is suggested by the pie-like contour of 
the adult insect which is particularly noticeable in the side view (see jig. 3).
