SCIENCE BULLETIN, No. 18. 



described an allied form under the varietal name of P. masTcdli var. viminaria, 

 upon the twigs of Viminaria denudata, and Hakea ilicifolia from the neigh- 

 bourhood of Perth, Western Australia. 



Adult female dark brown ; elliptical in form when alive, much wrinkled 

 when dead. Ovisac elongate, narrow, composed of felted white cotter. 

 Length of female, -/g inch, ovisac J inch. A median ridge down the centic 

 of the dorsum, margins flattened. Antennae eight-jointed; third longesl , 

 last three sub-equal, with long hairs at the tip. Fringed with fine blunt 

 spines round the margins. Maskell says it is allied to Pnhinaria maskelli., 

 var. spinosior, but besides its smaller size it differs in the feet, maigiral 

 spines, and dorsal elevation. 



In Mrs. Fernald's catalogue this sjDecies is -dimply made a variety, but I 

 see no reason for sinking its rank. 



Pulvinaria newmani, n.sp. (Fig. 6). 

 This fine species was collected in the Harvey district. Western Australia, by 



Mr. L. J. Newman, upon the twigs of an undetermined species of Jacksonia. 

 Adult females thickly, encrusting the twigs and 

 branchlets. Length, with ovisac, just under i inch ; 

 adult female without ovisac, after treatment in potash , 

 over I inch in length, but only ^V ii'ch when dried 

 against the ovisac. Dull reddish brown, broadly oval, 

 rounded in front, constricted behind cephalic portion 

 on either side, swelling out to anal segment, which 

 is deeply cleft with the extremities on either side 

 rounded. Antennae seven-jointed; first short, broad, 

 second longest, third and fourth equal, fifth to seventh 

 smaller. Rostrum well developed. Legs stout, 

 thighs thickened, tibiae stout at base. Whole surface 

 covered with fine scattered spines, with a distinct 

 fringe right round the outer margin of stout short 

 spines. 

 The ovisac is composed of felted white cottony secretion, which is waved 



with fine transverse impressions or in others slight parallel striae. General 



form cylindrical, truncate in front where in contact with coccid, but rounded 



on the apex. 



Allied to Pulvinaria maskelli, but differing in the larger size. Only seven 



joints in the antennae, and constricted on the sides of the thoracic segmental 



Pulvinaria faraddfha, Cockerell and Lidgett. 

 Victorian Naturalist, vol. xvi, p. 15. 1899. 

 The type was found upon the foliage of a wattle {Acacia melanoxylon) at 

 Mount Difficult, Grampians, Victoria.
