The Coccidae of South Africa.

INTEODUCTION. 
Material and Achioivledgments. — The material studied for this work is 
contained in the Coccid Collection of the Division of Entomology of the 
Union of South Africa. It comprises a large number of exceedingly inter- 
esting specimens, many of which were collected by Chas. P. Lounsbury 
and Claude Fuller when Government Entomologists of Cape Colony and 
Natal respectively. In addition there are many other specimens which 
have been collected by nursery or port inspectors or by other members of 
the staff. 
A few Ehodesian specimens are also included. Eupert W. Jack, 
Government Entomologist of Southern Ehodesia, has kindly promised to 
send others, and the descriptions of these, together with Mr. Jack's notes 
on the species, will be included in this paper. 
I am particularly indebted to the Chief of the Division, Chas. P. 
Lounsbury, for the privilege and opportunity of working over the collec- 
tion and for numerous valuable records made during the past eighteen 
years. 
To Claude Fuller, Assistant Chief of the Division, I tender my thanks 
for most able and willing assistance in a multitude of ways. 
The Entomologist of the Cape Province, Chas. W. Mally, has taken 
a great interest in the work, and has supplied a large amount of useful 
material, collected either by himself or by his assistant, C. P. van der 
Merwe. 
Albert Kelly, who has charge of the nursery inspection work in the 
Union, has submitted a large number of interesting specimens, and I 
am especially indebted to him for his most valuable records of host- 
plants. 
The other members of the staff have also given willing assistance. As 
the collector's name is given with each species I must ask them to accept 
this reference as the grateful acknowledgment of my appreciation. 
An Explanation. — The literature dealing with the Coccidae is, unfortu- 
nately, very scattered, and a large number of the older papers, which 
contain original descriptions, are practically unobtainable. 
In South Africa those interested in this group are obliged to rely almost 
entirely upon their own personal collection of Coccid literature, and the 
number of entomologists now in the country feel the necessity for a 
descriptive catalogue of all the species of scale insects known to occur 
here.
