The dermal pores over most of the body are small and simple ; some 
are supplied with bristles ; others with long subcutaneous tubes. In the 
circum-anal region there are numerous, scattered, large, disc-like pores 
and numerous long hairs, some of the latter reaching 100 /x in length. 
The anal ring is comparatively small, and hairless.

Subfamily MONOPHLEBINAE. 
The Monophlebinae are all comparatively large insects of exceptional 
interest. Eepresentatives of three genera are known to occur in South 
Africa, viz. Monophlehus, Icerya, Asjndoproctus. In the early stages of all 
and in all stages of the two first-mentioned, the ? insects have somewhat 
the appearance of mealy-bugs of large size, as the bodies are covered with 
a more or less dense covering of waxy secretion. In AspidojJivctus the 
derm becomes very hard and dense in the older stages, and has little or no 
secretionary covering. 
Gen. MONOPHLEBUS Leach. 
$ : Body usually dark brick-red in colour, more or less obscured by a 
coarse 'granular waxy secretion ; body-wall remaining thin and soft to 
maturity; legs and antennae well developed, dark in colour to black. 
Insects active and free-moving except at the ecdyses and time of oviposi- 
tion, when they cling to leaves or twigs and become fixed by tenent hairs 
on the venter. 
Antennae of 11 segments. 
^ : With two long caudal appendages to the abdomen. (In M. fulleri 
the caudal appendages are about as long as the body.) 
^ with compound eyes.
