„ Fuller, Natal Agr. Jn., p. 1035, 1907. 
Common names : — Ceylon, Lantana bug." 
England, " Kew bug." 
Natal, " Sugar-iced bug" (Fuller). 
America, " White-tail Mealy-bug." 
Ovisac : Varying in length ; may attain three times the length of the 
body ; white, except in old individuals, when it is often dirty or covered 
with "sooty" fungus, parallel-sided and upturned, rounded behind and 
attached to the body of the ? . The adult is active and carries the 
ovisac around with her until the young are hatched. Upper surface 
of ovisac with longitudinal furrows and median ridge flatly rounded 
and broad. 
Larva : Active, about 0-31 mm. long and 0*26 mm. broad ; very broadly 
and regularly oval. Legs very long ; legs II. longer than body (0-32 mm.). 
Antennae long (0-24 mm.), of 6 joints, which measure approximately : — 
(1) 34 ; (2) 35 ; (3) 34 ; (4) 30 ; (5) 37 ; (6) 100 Joint 6 with a strong 
blunt spine. 
Adult ^ : "A graceful little insect ... of a slaty-grey colour, with 
very long slender antennae, a single pair of greyish wings, and a tuft 
of long white silky filaments at the end of the body. The eyes are black 
and divided into numerous facets." [Green.) 
Adult $ : Varies in colour according to age, and ranges from light 
green to dark brownish-green, and later to nearly black. Antennae 
and legs fulvous. 
" Short-broad-oval, surrounded (except over the head) by a marginal 
series of snow-white, laterally connected lamellae, which, after the first 
three on each side, are directed backwards and downwards, gradually 
increasing in length, the posterior ones overhanging the marsupium ; but 
of these the middle three are shorter and more distinct, the median one, 
over the middle channel, shortest and broadest of all, either turned up 
vertically or horizontal, and having a median sulcation ; the dark surface 
of the body level, nude, the segmentation plainly discernible, but on the 
middle are two longitudinal, narrow, contiguous yet distinct lines of small, 
granulose, white, lamellate projections. These lines, beginning at the 
base of each antenna, extend backward for a short distance convergently, 
but almost immediately after each curves outward and again inward, so as 
to leave a small, dark, oval space between them ; then both are parallel, 
and close together up to the anal extremity." [Douglas.) 
When cleared and mounted the insect is about 1-7 mm. long and is 
slightly narrowed in front and broadly rounded behind. The antennae 
are 7- or 8-jointed, the segments varying in the 10 specimens examined as
