6. Cocciclomyces pierantonii Buchner, 1911, from Icerya purchasi. 
7. Cocciclomyces clactyloppii Buchner, 1911, from Pseudococcus citri. 
Some of these are not so widely separated as their generic names would 
suggest, while on the other hand Nos. 5, 6, and 7, which have been placed 
provisionally in the same genus, are three widely divergent forms. 
As a matter of fact my studies at Birmingham University under Pro- 
fessor F. W. Gamble, F.E.S., who brought this fascinating subject to my 
attention, seems to show that Nos. 1 and 2 are very closely related; 
Nos. 3 and 5 are probably of the same group ; but 6 and 7 are entirely 
distinct from one another and from the rest, except possibly from No. 4. 
Nos. 1 and 2 were isolated and grown on a variety of media, but never 
produced endospores. The forms represented by Coccidomyces dactylopii 
Buchner are probably restricted to the Pseudococcini. They are remark- 
able in that the individual organisms do not infect the ova independently. 
Instead of this a number together, enclosed in a " sferette," to use Dr. 
Pierantoni's term, acts as the infecting unit. (Plate XX., Figs. 34-39.) 
It is not my intention to deal with the subject further at this point, but 
merely to indicate a most fascinating field for study, and at the same time 
one which may be instrumental in elucidating several important points of 
relationship in the Coccidae. 
I am hoping to be able to deal with the subject of intracellular 
symbionts of the South African Coccidae at a later date.

''Adult 2 apodous; anal lobes rudimentary; antennae atrophied or 
rudimentary ; anal orifice with six hairs. 
Ovisac felted or solid and wax-like. 
Larva with the anal lobes well developed ; antennae of six joints ; 
anal orifice with six hairs " {Neio stead). 
1. Antonina natalensis, sp. n. 
(Plate XVIL, Fig. 8.) 
Adult 2 enclosed in a dense, tough, felted sac at the base of grasses. 
Ovisac : At first sight the ovisacs appear spherical, but on closer 
inspection they are found to be somewhat produced at the anterior end, 
so as to be really pear-shaped, 4-5 mm. long and 3'8 to 4 mm. broad. In 
colour the sac is yellowish-white to buif.
