Test of adult female (jigs. 1 zo 6) oval, convex above, the posterior ex- 
tremity slightly produced into a blunt point where is a small terminal aperture ; 
smooth, glassy ; colourless, or tinged with pale green or yellow ; transparent, 
revealing the form of the insect and eggs beneath. Dried examples assume a 
more definite ochreous colour, a brown patch at anterior extremity representing 
the dead body of the insect. Marginal fringe pinkish, consisting of a double 
series of glassy tubular filaments springing from the margin in pairs, each pair 
contiguous at the base and for the greater part of the length, but diverging 
laterally at their free extremities which meet the ends of the adjacent fila- 
ments—thus forming a series of narrow loops irregularly crossed by fine web- 
like threads (fig. 9); the outermost series continuous, except at anal extremity, 
and longest ; the second (nymphal) series less than half the length of the outer, 
and interrupted at more or less regular intervals ; an innermost (larval) widely 
spaced series of crook-shaped filaments. Length (without fringe) 2 to 250 mm. 
Breadth 1°10 to 160mm. Fringe, outer series o°I mm.; inner series 0:04 mm. 
Adult female insect at first more or less filling the test (7g. 2). After the 
deposition of the eggs, the abdomen becomes shrunken and the insect occupies 
the anterior part of the test only, the remaining cavity being packed with ova. 
Colour of insect dull green, the dorsum more or less motiled with reddish 
brown. Dried insect uniform reddish brown. Rostrum conspicuous, pyriform, 
approximately central (7g. 15). Antennze submarginal, rudimentary, consisting 
of an irregular tubercle surmounted by two longish stout bristles and one short 
spiniform hair (fg. 18). Spiracles conspicuous, subglobular, at a considerable 
distance from margin, with scattered series of minute pores connecting them 
with the margin. Abdominal extremity (jg. 16) slightly cleft ; anal tubercles 
broad and stout, but not very prominent, each with a long stout seta at its apex 
and one or two short stout spines near the base. Anal ring stout, with six 
stout hairs which just project beyond the margin. Margin with a continuous 
series of large approximately circular thick-rimmed pores, in pairs, and a 
double ventro-marginal series of minute circular pores (fig. 17). There are 
some scattered paired pores of a slightly larger size on the dorsum, and many 
simple circular pores on the ventral surface of the abdomen. Length of ex- 
tended insect 1'25 to 1°75 mm. Breadth oo to 1'25 mm. After oviposition 
the insect becomes greatly shrunken and does not resume its original propor- 
tions during maceration. 
Early adult female at first pinkish (fig. 10), later dull green (fg. 7), finely 
maculated with reddish brown. . The outermost series of the fringe is at first
