The Coccidae of South Africa. 
157 
clusters of large, thick-rimmed pores, each with a pentagonal lumen, which 
occur over the whole surface, but are less pronounced on the median area. 
The number of pores in a cluster varies from 2 to 25, and averages 12 
or 13. 
The truncate spines are very inconspicuous, small and slender, taper- 
ing slightly towards the extremity, some of them almost hair-like. They 
are scattered very sparsely over the body, but are grouped more closely on 
the area surrounding the anal orifice, where they are mingled with some 
simple pointed hair-like spines. 
Length of adult female (under compression) from 4 to 6 mm. Breadth 
3 to 4'5 mm. Average dimensions 4-75 x 3*87 mm." (Green.) 
Habitat : On Ojmntia tome^itosa, 0. decumana, and Noimlea cochineli- 
fera in Botanic Gardens, Cape Town. 
This species has been established in Cape Town for many years. It 
does not have the toxic effect on the host-plant which is so striking in 
C. indicus.

Coccus confusus capensis Green, Journ. Econ. Biol., p. 91, 1912. 
" Adult female profusely covered with white mealy secretion whicli 
more or less completely conceals the form of the individual insects. 
Broadly oval, usually narrowed behind. 
Eyes moderately prominent ; not densely chitinous. 
Antennae small, basal joint very broad ; 2nd joint ring-shaped ; 3rd 
and 4th approximately equal, and twice as broad as long ; 5th and 6th 
smaller, broader than long ; 7th irregularly ovate, longer than broad, 
tuberculate. Total length of antennae 0-15 to 0-17 mm. Breadth of 
basal joint 0-07 to 0-09 mm. 
Legs small, moderately stout; femur and trochanter together 0*2 to 
0*23 mm. ; tibia 0*08 to 0-12 mm. ; tarsus (without claw) O'l to 0'12 mm. 
Dermal pores conspicuous, in dense clusters (especially towards pos- 
terior extremity) ; a few single pores and small scattered groups ; largest 
groups with 30 pores ; average 15. 
Truncate spines numerous and conspicuous ; stout, cylindrical ; pro- 
portionately shorter than in typical confusus or neiusteadi ; diameter of 
base usually much more than half the total length of spine. 
Length of body (under compression) from 2*5 to 3-5 mm. Breadth 
2 to 2-75 mm. An average of sixteen examples gives a dimension of 
3 X 2-27 mm." [Green.)
