Sphaerococcus newmanni, n.sp. 



The coccids, forming curious rounded tests of secretion upon the twigs of 

 a titree {Melaleuca sp.), were collected by Mr. L. .1. Newman, at Busseltown, 

 West Australia. 



Female puparium formed of a thin skin of light biscuit to yellowish brown 

 waxy secretion, which dissolves readily in caustic potash. The base is 

 attached to the surface of the bark, swelling out on the sides, and broadly 

 rounded to the summit ; it appears to be formed of three sections coalescing 

 along the impressed lines, one of which divides the centre and the other circles 

 round the apical orifice, which spins out in a little boss in the centre. Length 

 of puparium, one-eighth of an inch. 



Fig. 9. —Sphnerococcus neivmanni. ns.ji. 



Adult female dark reddish brown, much wrinkled, oval, and when treated 

 with ptoash giving off a rich red tint; length, about one-tenth of an inch; 

 she rests in the puparium with the anal segment curving round to the apical 

 orifice ; the cephalic portion resting upon woolly filaments, which protect 

 the larvpe. Antennae and legs wanting; rostrum distinct, with a curious 

 dark yellowish brown band extending to the anal segment, before reaching 

 which it forms a lance-headed ])atch, and then a transverse band, producing 

 a cross-like pattern, with an opaque granulated structure on the anal segment. 



Larvae bright red, almost cylindrical, elongated ; legs long, well developed ; 

 antennae composed of four joints, the third the longest, clothed with fine 

 bristles that extend over the terminal joint.

 The type specimens were found upon the bark of two different wattles 

 {Acacia linifolia and A. ohtusiflora), growing at Hornsby, N.S.W.
