Pvlvinaria salicornice, n.sp. 



This coccid was found by Mr. C. French, junr., upon the foliage of an 

 undetermined species of Salicornia, growing at Little River, Victoria. The 

 adult female is reddish brown, with the outer margins lighter coloured; 

 general form broadly rounded, convex, and wrinkled when dry on the dorsal 

 surface, concave beneath ; no distinctive structure after treatment with 

 potash; antennae small, six or seven jointed; first joint broad, short, second 

 shorter than the third; terminal one small; legs moderate; and segment 

 round on either side, with the angulated processes on either side of the anal 

 opening large. Length, ^ inch. 



Ovisac composed of soft white w^oolly filaments forming a pad upon which 

 the coccid rests, and extending into a round mass behind ; the margin of the 

 C03cid is often buried in the woolly secretion, so that only the back shows. 

 Length, with coccid, 4 inch. The species was determined and given the 

 above MS. name by Mr. E. E. Green, and w-as given to me at his suggestion 

 by Mr. C. French, junr

This is one of the commonest woolly coccids in the vicinity of Sydney and 

 along the coast, being found chiefly upon the branchlets of Kunzea capitata 

 and other species of this genus. So thickly does it infest the small twigs 

 that they are often completely enveloped 

 for inches with balls of white loose filaments. 



It has been recorded upon another native 

 shrub {Daviesia, spp.) and upon the orange, 

 but I have never seen it upon any citrus 

 tree. 



The adult female varies from dull yellow 

 to dark reddish brown; general form oval, 

 slightly convex; firmly attached to the" 

 bark of the twig; enveloped in the ovisac, 

 which consists of loose, cottony, matted 

 filaments, somewhat curled and felted, 

 irregularly rounded, measuring often | inch 

 in diameter. The enclosed adult coccid 

 measures about | inch. "«• i—Putvinana ucta
