to hatching, it assumes a purplish to brownish tinge. In shape it is spherical with a 
more or less Hattenecl base. Diameter -Jo-So mm. 
The sculpturings on the shell are as follows ; a small depression round the microphyle 
is surrounded by a slightly raised ridge. Similar concentric ridges succeed each other 
over the whole surface of the egg. Cutting these are upright ridges, converging towards 
the centre and thus enclosing little depressions. Within these depressions the shell is 
faintly sculptured. A number of the upright ridges end before reaching the top. At each 
point where the upright and the concentric ridges intersect, a spine arises, slightly chrbbed. 
Larva (fig. 2).—A thick-set apple-green caterpillar with rosy-red markings. 
Length of mature larva, 25-30 mm. 
In clearly marked specimens the following characteristics can be determined ; — 
Head, chestnut-brown. Thoracic shield brown with a greenish tinge, and cut by a 
pale median line. 
A median stripe on each segment forms an interrupted median dorsal line. On either 
side of the median stripe on each segment is a similar stripe sloping downwards and 
backwards. Spiracles, black. On either side of the first segments, anteriorly placed 
to the spiracles, is a black dot, from the centre of which arises a black hair. On the 
second segment is a transverse row of twelve black dots, each surrounded by a rosy 
ring and liearing a hair. On either side of the sloping stripes on each segment is 
a black dot, bearing a hair. Immediately above, below and posterior to each spiracle, is a 
black dot, surrounded by a rosy ring and bearing a hair. A row of similar dots is 
situated immediately above the setting on of the legs. An anal shield of greenish brown 
extends slightly over the margin of the twelfth segment. On young larvae the anal shield 
is very prominent and dark in colour, as is often the thoracic shield. 
Venter, apple-green, with the exception of the fourth and fifth segments, which are 
ringed with red. 
These markings are subject to considerable variations. 
Pupa (tig. 4).—Light yellowish chestnut-brown, sometimes with a greenish tinge. 
Length, 13-14 mm. 
Thorax, rather lighter in colour than the abdomen. A darkish median dorsal line 
starts on the crest of the thorax and extends to the tip of the abdomen. Spiracles and 
eyes, reddish to dark brown. 
Adult (fig. 3).—A greenish-pink moth with a length of 12-14 mm., and a wing 
expanse of 30-32 mm. Described from a faded and damaged specimen. 
Head and thorax, reddish green. Fore-wings, dull pink with a green triangular mark 
at the base and a broad green transverse stripe towards the margin. Fringe, greenish. 
Ilind-wings, silvery white, suffused with pink towards the margin. 
.\bdomen, silvery white. 
VreveiitiiDis uiid re in ('dies. —Until its life-history and habits are better known, the only 
remedy that can be suggested for this pest is that of hand-picking the larvaj early in the 
season. Over small areas it might possibly prove practicable to collect the eggs, as they 
are very easily seen when first laid.

Two species of Hea beetles have been observed attacking cotton— XLoIra uniformis, 
•lac. (tig. 4) and an undetermined species of Aphtona (fig. 5).
