The trochanter is normal (Fig. 13). Cf. Ps. natalensis (Fig. 14). 
Mentum long (138 acute (Fig. 13a.). 
Setae of anal lobes may reach 205 ^ in length. 
Setae of anal ring about 135 jx. 
Host-plants : Citrus, Grevillea rohiista, hibiscus, etc. 
Habitat : Bathurst, CP., Natal Coast, and Pretoria, T.P. 
The records of this species in South Africa are : — On hibiscus from 
Eichmond, Natal (U.S.D.A. Ent. Div. No. 7232). On orange from Natal 
(Cockerell); orange, Capetown (Q.S.D.A. Ent. Div. No. 7706); Native 
tree, Sp. indet.. Natal, Lounsbury, October, 1914 ; Grevillea rohusta, 
Pretoria, Mr. K. Munro, November 9, 1914. 
The Washington reference No. 7706 was in all probability recorded 
from Capetown because the material was sent from that town, but it is 
clearly recalled that it was collected in Bathurst (Lounsbury). The 
species has never become established in the Western Province of the 
Cape as far as I have been able to ascertain. 
The most closely related South African species are Ps. natalensis and 
Ps. solitarius spp. n. q.v.

(Plate XVIII., Figs. 14, 14a.) 
Dactyloinus filamentosus Ckll., " small variety," Entom., xxxiv., p. 224, 1901. 
Ovisac : The ovisacs are long and narrow, and are clustered one above 
the other in the leaf-sheaths, often forming a row two inches in length. 
They are entirely closed, and have dense white walls of felted material, 
often roughened on the outside, and brittle when dry. They enclose the 
viviparous female and the larvae. It is remarkable for a truly viviparous 
mealy-bug to be enclosed in so dense a sac. The majority of the ? speci- 
mens mounted fresh by C. Fuller contain well-developed larvae. 
$ . Not adult : 1-12 mm. long when mounted, has antennae 6-jointed 
measuring as follows :— (1) 34; (2) 34 ; (3) 34 ; (4) 18 ; (5) 20; (6) 68. 
? . Adult : In colour, both dry and in KOH this insect is like 
filamentosus. It also has 7-jointed antennae of very similar length, but 
apart from these points it is an entirely different insect. Ps. filamentosus 
Ckll. is much larger, constructs a large cottony ovisac which contains large 
numbers of eggs, but does not enclose the insect itself. But the most 
striking character of natalensis in mounted specimens is the remarkable 
trochanter, which is quite different from that of any other mealy-bug 
known to me. It is shoe-shaped and has a distinct conical protuberance, 
which bears a very strong, short, conical spine (Fig. 14).
