SUPPLEMENT ARY NOTES ON COCClDyE OF CEYLON, 1027 
and tarsus completely fused together without trace of division. Tarsal 
digitules slender, minutely knobbed ; ungual digitules slightly dilated. 
Anal operculum (c) oblate ; the base of each valve longer than its outer 
edge, the apices incurved ; a stout spiniform seta on the inner edge of each 
valve ; three or four circular cicatrices, nearer the apex, suggest the 
earlier presence of other similar setae ; a broad, sharply defined densely 
chitinous hoop surrounds the upper half of the operculum. Margin with 
long, slender setae, most of which (in the example under examination) are 
indicated by their basal sockets only. No stigmatic clefts ; but the mar- 
gin, opposite each spiracle, bears two, widely separate, stout, acuminate, 
irregularly conical spines (e). Derm without conspicuous cells, but with 
scattered circular pores and small setae. Length mm. 
Nymph with antennae and limbs similar to those of the adult insect. 
Valves of anal operculum (/) with apices bluntly pointed and bearing a 
longish stout seta mounted on a small tubercle ; a similar seta within the 
inner margin, about half way between the apex and the base, and indi- 
cations of lost setae on the apical half. Margin with many strong setae, 
becoming longer snd stouter towards the extremity of the body. Stigma- 
tic spines similar to those of the adult insect. 
Larva with stigmatic spines as in the later stages. Antenna {g) 6-joint- 
ed, the 6th with a very long lateral seta that exceeds the length of the 
antenna itself. Tarsus and tibia of approximately equal length. Margin with 
short curved setae, increasing in length towards the posterior extremity. 
At the base of a grass plant, below a large stone, on patna land; 
attended by ants. Pattipola. Described from a single adult female, 
and several nymphs and larvae.
