West Australian Coccid^. 449 



panels, which when viewed from the inside are seen to be united to 

 one-half their height. 5 chamber balloon -shaped. 



Adult 9 segmented, sub-globose ; abdomen not prolonged into a 

 tail ; almost filling chamber. Colour pink. Antennae atrophied, 

 close, short, and tapering, surmounted with a few hairs ; 6 or 7 joints. 

 Legs short, stout ; tibia longer than tarsus ; tarsus clawed. Rostrum 

 large ; mentum conical, trimerous (1), apex haired. Anal tubercles 

 absent. Anal ring not conspicuous. Dorsum clothed with numerous, 

 acuminate, yellow spines. Viviparous. 



Larva elongate, fringed with spines. Anal tubercles bearing setae 

 and spines. Antennae of 6 joints. Legs thick, tarsus slightly longer 

 than tibia, upper and lower digitules knobbed. Colour crimson. 



The galls of this species are formed by the insects 

 attacking and diverting the apical growth of the branchlets. 

 In appearance they much resemble the galls of Cylindro- 

 coccus. The young galls, which are almost as large as those 

 containing the adults, are soft, and three or four young are 

 usually found in them; what becomes of the additional in- 

 mates I am unable- to say, but it is probably a case of the 

 " survival of the fittest." Named after Mr. A. M. Lea, 

 Government Entomologist of Tasmania. 



29. Sphmrococcus tepperi, sp. n. (PL XV, fig. 16.) 



Galls formed like those of S. socialis, Maskell, being composed of 

 aborted leaves and occupied by many Coccids. Spherical, flattened 

 at the base and apex ; the points of the aborted leaves protruding. 

 Colour green. 



Adult $ flat, elongate, pyriform ; head pointed ; abdomen widely 

 rounded behind ; abdominal segments chitinous ; colour yellow. 

 Eyes black. Antennse projecting on each side of the head, short, 

 thick, probably 5-jointed ; apex truncate, haired. Mentum dimerous. 

 Legs, anterior 4 absent ; posterior pair atrophied, apparently 2- 

 jointed, with circular pores, and resembling in shape those of S. 

 stypheli^e, Mask. Anal orifice simple, with 4 spines above and a row 

 behind. Spiracles large. Length 0"04 inch. 



Taken on a small Melaleuca or Kunzia. I have much 

 pleasure in naming this species after Mr. J. G. O. Tepper 

 of Adelaide Museum, S. Australia.

Adult 9 s stationary, globular, green, covered by several convex 

 superimposed scales of white wax, congregating together and forming
