PULVINARIA THESPESIA, sf. nov. 
(PLATE XCVIL.) 
Adult female (fg. 1) at first pale bright green, dorsum powdered with white 
mealy secretion ; afterwards greenish ochreous, or dull ochreous when dry ; derm 
soft, shrivelling after gestation. Antenne (fg. 2) eight-jointed, of which the 
third is much the longest (almost equal to the next four together) ; fifth either 
equal to or longer than fourth ; formula: 3 (5, 4), (2, 8), 1 (6,7); or 3, 5 (2, 4, 8), 
1 (6, 7). Legs (fig. 3) stout. Tarsus rather strongly curved ; digitules normal. 
Margin (fg. 4) closely set with stout truncate spines, those in stigmatic cleft 
longer and pointed. Valves of anal operculum (fg. 5), with outer angle broadly 
rounded ; apical angle truncate and irregular, inner edge irregularly indented. 
Derm without conspicuous cells, but with numerous minute circular pores on 
dorsum, especially towards posterior extremity. Ovisac white, elongate, flat- 
tish ; finely longitudinally ribbed. Length of insect 6 to 950 mm. Breadth 
4 to 450 mm. Total length, with ovisac, when fully developed, from 15 
to 20 mm. 
Male puparium (jig. 6) creamy white, a small rounded process at centre ot 
dorsum ochreous; opaque, strongly convex. Thick cushions of wax on the 
median plates, the anterior cushion concave behind. The medial cushion with 
a rounded process in front, which fits into the concavity of the anterior cushion. 
Lateral plates with a projecting flange along their upper border. Length 250mm. 
Adult male unknown, 
On ‘Suriya’ (Thespesia populnea). Jaffna; March. 
Closely allied to P. maxima, Green (from Java), but rather smaller. Dis- 
tinguished by the relative proportions of the second and third antennal joints. 
In ¢hesfesie the second is more than three times the length of the third, while 
in maxima it is rather less than twice the length of the following joint. Differs 
also in the absence of conspicuous derm cells.
