110 CHAS. K. BRAIN. 



decidedly reddish. The stem beneath the normal galls remains green, but the 

 broad attachment is half green and half brown. The outside of the gall is not 

 smooth, but is much wrinkled and appears bark-like. The orifice of the gall is 

 conical, the thin outer edge being brown and hard in texture, the inside appearing 

 softer and green. At the base of the wide opening there is a minute circular pore. 

 When opened in the fresh state the walls of the gall are hard and woody, from 

 1 mm. to 1*5 mm. in thickness, with the outer bark loosely attached. 



Male puparium about l'i mm. long and 0"7 mm. broad, almost parallel-sided, 

 with rounded extremities ; margin with a fine fringe of glassy filaments about one- 

 fourth of the width of the body in length, and the dorsum with two submarginal 

 rows of very long white glassy filaments many times the length of the body (fig. 74c). 

 The puparium itself is delicate, glass-like, not divided into definite plates as in the 

 <$ Lbcaniinae. The posterior extremity is broadly and roundly excavated. Body 

 of the i mm ature male, as seen through the puparium, pinkish. 



The adult female at the time the eggs are developing fills approximately half the 

 space of the gall, being very convex, with the blunt caudal extremity fitting tightly 

 into the conical portion near the aperture. The dorsal surface is distinctly segmented 

 and is flat with prominent ridges, as shown in fig. 74a. 



The colour of the body is delicate flesh-pink, slightly obscured by a thin layer of 

 white powdery secretion. In boiling KOH the body becomes purplish red, and the 

 liquid is deeply stained with the same colour. 



Anal ring in a delicate tube beneath the two anal plates. The chitin of this tube 

 is very delicate, but bears a few scattered hairs and simple glands and is pleated 

 longitudinally, so that it looks like a large number of long bristles when seen in 

 optical section. The anal ring bears 6 very stout bristles. 



Legs small, rudimentary (fig. 786, c). 



Spiracles very large. Mouth-parts comparatively very small. Integument clear, 

 with scattered simple glands and numerous long bristles. Antennae apparently 

 entirely absent. 



Larva with marginal series of short blunt, very stout spines, about 32 on each side, 

 but no dorsal spines. Anal lobes and armature of larva reminding one of those of 

 Cerococcus. Eyes darkly pigmented. 



Remarks : A number of the galls of this species which contain healthy females 

 also harbour a large coleopterous larva. I imagine that this species feeds upon the 

 wax and other secretions of the insect. In other cases comparatively large galls 

 were opened which showed no trace of the Coccid, but contained a small dipterous 

 larva. In a few instances living galls were opened that contained a large body of the 

 Coccid in which the integument was dry and brown, and this on being opened 

 exhibited a number of maggots (8-10), also Dipterous. Dead galls, apparently of 

 last year's growth, harboured a multitude of specimens in great variety. These 

 include a small centipede, several species of mites, a mealy bug, and a minute honey- 

 coloured ant, the entire nest of which seems to be in a single gall. 



Habitat : On native vine (Cissus cuneifolia) ; collected by C. Fuller on Natal 

 Coast, near Durban. 



Collection No. : 40.
