Lecanium ornatum, Hempel. 
Adult female ovate, asymmetrical; dorsum not very con- 
vex, dark brown in colour, with a light marginal band. In 
the old specimens the dorsal derm is hard an:t bears about 
twenty-four radiating ridges around the margin and a few 
nregular ridges on the central portion. The entire derm is 
covered with a thin white powdery secretion. Size 4 milim. 
long, 3 millim. wide, and °750 millim. high. Anal clett 
*625 millim. long; sides not contigtious. 
Boiled in a solution of KOU it colours the liqnid light 
brown. After boiling the derm becomes colourless in tho 
younger specimens, but remains hard and brown in the older 
specimens. The derm has rows of peculiar round or oval 
groups of glands corresponding to the ridges. Thus the 
dorsum is divided into twenty-four marginal and twenty-two 
to twenty-four central areas. ‘These groups of glands are 
both large and small, and each contained from ten to thirty of 
the small elliptical hyaline gland-spots. ‘The ventral derm 
contains many large tubular glands and groups of simple 
round spinnerets, especially near the margin, 
The antenne are variable, usually of eight joints, although 
some individuals have antenna of seven Joints. All the 
joints bear hairs, but joints 8 and 4 are sometimes hairless.

digitules of claw twice the length of claw, with the ends
