 Pro. Linn. Soc. N.S.W., vol. xxiii, p. 378, pi. ix, f. 16-20, 1890. 



Forming reddish brown to dull green rounded fluffy excrescences, com-

 radiating from the basal gall, on the side 

 or tip of the branchlet of several species 

 of Melaleuca, growing along the coast of 

 northern New South Wales and southern

 face, and is embedded in the central woody cavity. Diameter, about 1^

S])haerococcus froggatti, Maskell (Fig. 5). 

 Trans. New Zealand Institute, vol. xxvi, p. 94, pi. vii, f. 1-7, 1893. 



This coccid is very common upon the titree {Melaleuca linarijolia), growing 

 in the vicinity of Sydney. 



The female coccids form brown or reddish yellow 

 galls, attached at the base to the twigs, cup-shaped 

 ill form, but covered with curling cylindrical pro- 

 cesses, often much longer than the basal gall, so that 

 the whole gall is enveloped in a feathery mass of 

 these filaments, though they spring from the upper 

 surface. Galls variable in size, from one-fifth to 

 half an inch in diameter. 



Fig. 5.—spitaeiococcaii,f>o(jgatti. The adult female develops on the gall cavity, 

 dull red in colour: she is dusted with white meal. 

 and has a bluish grey tint ; general form subglobular, tapering to the anal 

 extremity. Length about one-twelfth of an inch. Antennae aborted, 

 indistinct; appear to consist of two joints. Legs wanting. There are four 

 large spiracles. The epidermis bearing a number of circular multilocular 

 spinnerets, and a few fine spiny hairs, thickest on the abdominal region.
