pattern of egg-shaped bodies bedded in darker brown. Dorsal sin face ccvtied 

 with a white mealy wax-like white bloom, and the outer margin fringed with 

 fine setse. General foim broadly rounded, flattened, or very slightly convex 

 on the dorsal surface, rounded on the margins, but showing two slight inden- 

 tations on either side from which run up tiansveise lines meeting the trhoit 

 carina in the centre of dorsum ; anal opening and cleft large ; ventral suiface 

 flattened with four white transverse lines in centre; legs long and sler.der; 

 rostrum large; antennae long, slender. Length, f inch; diameter, i inch. 



Male test white, semi-oj)aque, slightly granidated and mealy; elongate, 

 oval; upper surface smooth, convex, not angulated, with fine white lines 

 traversing the dorsum and joining in a V-shajDed point at the anal opening. 

 Length, iV inch. 



This species comes near Lecanium expansion in its broad flattened form 

 and lateral constrictions.

This Lecanium has been irjtroduced into Australia on hothouse plants, 

 and is common on palms, ferns, &c. Signoret described the type upon the 

 foliage of a palm {Caryota iirsus) at Montpellier; Maskell desciibed it tn the 

 foliage of Laurius nohilis, from Sydney. In the Botanic Garders, Sydney, 

 it is common on many plants, but is nearly always found upon Coccoloba 

 flatyclada, a curious flat-leaved plant, native of the Solomon Islands. 



The adult female is flat, slightly convex, very irregular in foim, but ii&ually 

 broad oval, narrowest in front, and one side more arcuate than the other, 

 which may be almost straight. When alive it has a greenish tint, which 

 fades into a reddish-brown in the centre surrounded with a dull yellow mar- 

 gin. The whole surface is covered with fine reticulations, with the outer 

 margins having two deej) indentations on either side, with distinct lines 

 running across to the doisum, while the whole is distinctly broken with 

 finer transverse lines, so that it looks as if the margin was made up of a 

 number of plates, with a fringe of fine scattered hairs or setae along the edge. 

 Antennae and legs well developed. Length, i of an inch. 



Male tests crystalline white.
