Ceroplastes purpureus, Hempel. 
Adult female scale thin, small, light brown, divided into 
seven distinct plates. The general outline is that of a rect- 
angle with the sides nearly perpendicular. In the younger 
specimens the plates are distinct and are separated from each 
other by dark brown lines; in the older specimens the dorsum 
becomes more convex, the plates become indistinct, and the 
colour changes to purple. Dorsal nucleus present, white, 
slightly elevated ; lateral nuclei indieated by slight depres- 
sions. Wax very thin and dry, but tough. Length 2°75 
millim.; width 2°10 millim.; height 2°1 millim. Denuded of 
wax derm hard, shining, dark red, roughened by many small 
gland-pits. Caudal horn very small, dark brown. Boiled in 
a solution of KOH it colours the liquid dark red. The derm 
is chitinized and becomes light brown in colour.

first pair of legs: coxa 53, femur and trochanter 102, tibia 66,
