CHAS. K. BRAIN. 



At a younger stage — when about 2*5 mm. long — ^the body is red-brown, rugose at 

 the edges, with the median keel not prominent but smoother than the remainder 

 of the body. 



The antennae are 8-jointed ; range in f.i : (1) 31-45, (2) 50-62 (3) 95-108, 

 (4) 54-65, (5) 32-44, (6) 27-34, (7) 27-34, (8) 31-37. 



Leg I : coxa 102, femur + trochanter 245, tibia 165, tarsus 85, claw 20/^. 



Tarsal digitules moderately long (70//), slender hairs with their distal ends sUghtly 

 clubbed. Lower digitules short, broad. Marginal spines short (27//), truncate. 

 Anal plate about 155// long. Stigmatic cleft wiiih three comparatively slender 

 spines, laterals about 34//, median similar but longer (61 ju). 



Male puparium about 2 mm. long and 1 mm. wide, dark red when containing the 

 insect ; white and glassy when empty. The divisions of the test are very prominent, 

 opaque white ; the remainder being ■£ wrinkled and almost hyaline. 



Adult (J (J were emerging in large numbers when the material was received, 

 5th April 1916. 



Copulation was observed in a number of cases, the $ in each case measuring about 

 4 mm. in length. The body of the male was curved downward admitting the sheath 

 into the cleft of the 5* During this 'process the two long waxy filaments of the (^ 

 stood erect. 



The adult (J is about TO mm. long, rich red-brown in colour, with two long waxy 

 caudal filaments about half as long again as the head and body combined, without 

 the antennae. The body, legs, and antennae are all red-brown. The head is slightly 

 darker. The scutellum is polished at the edges, with a sunken, matt, central patch. 

 The wings are hyaline, matt, extremely iridescent, with a strong sub-costal, cochineal 

 red band. 



When mounted, the following measurements may be taken as an average : —

Habitat : On a native shrub ; collected by C. Fuller, Illovo River, Natal, April 

 1916. On leaves of Chilianthus oleaceus, Burch (Loganiaceae), Bloemfontein, 

 O. F. S. ; collected by J. C. Faure, April 1916.

This insect, with the ovisac completed, is similar in appearance to F. oleae 

 '(Costa) but, according to Signoret's description of that species, the adult has 

 6-jointed antennae. 



222. Filippia carissae, sp. n. (Plate i, fig. 236). 



This species differs from F. africana in the following respects : — 



The ovisac is a little larger and generally less compact ; often split around the 



edges (fig. 236). The antennae are more variable, 7 or 8-jointed, range in ii : —
