On twigs of an undetermined tree ; Maha Illuppalama. Differing from 
discrepans in the longer, more slender and simpler marginal setse. 
Lecanium ixorae, n. sp. (Fig. 23.) 
Adult female ovate, flattish, thin. Colour 
pale fulvous. Antennae 6 to 7 jointed. Legs 
small but robust ; tarsus almost as long as 
tibia. Marginal setae small, their extremities 
ciliated. Stigmatic spines (a) three, the 
median spine twice as long as the other two. 
A single row of conspicuous pores extends 
from each stigmatic cleft to its associated 
spiracle. Anal operculum (6) elongate, the 
basal margin of each valve twice as long as 
its outer margin. No visible dermal cells. 
Length 1’5 to 2 mm. 
On Ivora coccinea ; Heneratgoda. 
The structural characters are very similar 
to those of Lee. psidii ; but ixorcB is a much 
smaller, flatter and less densely chitinous 
insect. These differences are not due to 
immaturity. The specimens under examina- 
tion were fully developed and contained ova. 
The complete absence of dermal cells is a 
distinguishing character.

and marginal setas,

Lecanium latioperculatum, n. sp. (Fig. 24.) 
Adult female broadly ovate, mode- 
rately convex ; derm soft, wrinkling 
when dry. Colour yellowish fulvous, 
the intestinal loop visible as an irre- 
gular reddish line. Antennae 7- joint- 
ed ; 3 and 4 longest, equal. Limbs 
well developed ; tarsus about three- 
quarters the length of the tibia. 
Stigmatic spines (a) small, scarcely 
projecting beyond the margin, the 
median spine twice as long as the 
other two ; Marginal setie (b) short, 
curved ; more or less flattened, expan- 
ded and fimbriate at extremity. Anal 
operculum (c) broader than long, the 
outer margin of each valve rounded 
and often deeply incised towards the 
middle. Dermal cells inconspicuous, 
small, scattered. Length 1'75 to 2 
mm.

On smaller branches of an undeter- 
mined shrub ; Peradeniya. Attended 
by ants {CEcophylla smaragdina) \ and often included in their silken enclo- 
sures. 
Examples from Datticaloa have the marginal setie more slender and less 
distinctly fimbriate.
