It will be obvious that no general scheme can be given for the 
antennae of this species, but the 9-jointed forms do show some 
constancy in the relative size of the segments.

In the measurements of the legs the specimens seem to fall into two 
classes, of which the following are types : —

The setae of the anal lobes vary from 170 to 210 fi with 185 ^ the 
mode; those of the anal ring vary between 135 ^ and 152 /z. 
The eyes are pronounced, but flattened ; and the mentum is short, 
averaging about 85 ft in length. 
Although the measurements of the antennal segments and those of the 
legs vary so greatly, this mealy-bug is readily distinguished from any 
other found in South Africa by other characters. The ventral median 
plates alone would separate it. I am at a loss to explain their function.
