Description. 
When this insect first appears on the leaves of the host plant, 
probably soon after leaving the egg, it isa minute little coccid 
covered with white woolly hair. Soon afterwards as it in- 
creases a little in size, the larva loses this hair and is yellow in 
colour, changing to a yellow-brown. At this stage it is sti ] 
less than one-sixteenth of an inchin size. A fortnight later 
the brown colouring becomes more pronounced, the scale being 
then about th of an inch long, elliptical in shape, convex on 
dorsal surface, and flat beneath, with three pairs of black legs, 
black antennz, and a longish black proboscis. After a 
further period of fifteen days has elapsed the larve are about 
4th inch in length, dark brown on the dorsal surface, changing to 
orange yellow or pale canary yellow in the older specimens ; 
ventral surface canary yellow ; legs, antennz, and _ proboscis 
black. This colouring remains much the same till the insect

and by planters in the district who have known the insect locally for some 
years. 
I am indebted to Mr. Oliver for drawing my attention to the insect in 
the first instance on my arrival in the Dun early in 1901.
