Test of adult female (fg. 1) very broadly oval; shortly pointed behind, the 
extremity with a small but conspicuous notch ; with a median and two lateral 
longitudinal rounded ridges, the latter considerably curved. Greenish yellow 
at first, afterwards lemon-yellow; the fringe with a slightly reddish tint ; 
dorsum with some tufts of short brownish red filaments, disposed in three 
series following more or less the lines of the ridges, the median series alter- 
nated with short colourless curved filaments. Younger examples sometimes 
with a median longitudinal reddish stripe. Fringe (fig. 2) very deep and 
close ; composed of the usual three series ; the outermost arranged in about 
twenty-eight more or less symmetrical bundles, with a pair of strongly 
divergent filaments in the interspace between each bundle; the second 
(nymphal) series less than half the length of the former, similarly divided 
into bundles the filaments of which are more widely spaced, the outer pairs 
of filaments of each bundle widely divergent, their ends meeting across the 
wider interspaces ; the third (larval) series consisting of twenty-eight paired 
filaments curved in the form of crooks, altérnating with the bundles of the 
outer series, the six hindermost united for their whole length and curved 
towards the posterior extremity, the remaining eight (on each side) with their 
filaments divergent from the base and curling in opposite directions ; alter- 
nating with these curled filaments are twenty-eight short pairs which may be 
easily confused with the members of the nymphal series, but actually belong 
to the imaginal series, being secreted by a special set of widely spaced paired 
glands on the adult insect. Length 1°50 to 1°75 mm. Breadth 1°25 to 
1'50 mm. 
Adult female, before oviposition (jig. 3), broadly oval, slightly pointed 
behind. Posterior extremity (fig. 4) with the lobes moderately prominent, 
each bearing a longish stout seta; the small inner lobules each armed with a 
conspicuous spiniform hair ; the usual third pair of spines on the intermediate 
margin apparently wanting. Anal ring with six stout hairs, scarcely projecting 
beyond the margin. Postanal chitinous bar narrow. A conspicuous chitinous 
paraphysis extending on each side from the base of the inner lobule almost to 
the anal ring. Clypeus comparatively short and broad. Rudimentary antennz 
with three stout curved hairs. Spiracles occupying a position approximately 
half way between the margin and a median line. Marginal glands (jg. 5) 
consisting of a continuous series of large 8-shaped pores, within which, at 
regular intervals, is a set of twenty-eight similar paired pores (which give rise
