This is an introduced species, recorded from New Zealand and Australia ; 

 almost cosmopolitan in its range, on many garden shrubs, such as Camellia, 

 Euonymiis, Brassia, Phaius, &c. 



It is the common hothouse scale in England and France, appearing on the 

 underside of the leaves, where, after the adult female has deposited her eggs, 

 she usually shrivels up and, falling off, leaves behind her the white cottony 

 ovisac enveloping the eggs. 



Newstead says : "' Adult female in life distinctly cordate, but becoming 

 more wrinkled after gestation. Colour pale yellow ; lower half of the body 

 mottled with reddish brown or brightly ochreous; 2-3 mm. in length." The 

 ovisac, either curved or straight, is usually five to eight times the length of 

 coccid.

Pidvinaria greeni, n.sp. (Fig. 4). 

 This fine species comes from Condobolin, New South Wales, infesting one 

 of our inland scrub trees {Myoporum deserti). I have named it in honour of 

 Mr. E. E. Green, who has assisted me so much in this work. 



Adult female after gestation, 

 buried in the ovisac, measuring 

 with the surrounding ovisac, 

 i inch. Much wrinkled, yellow- 

 ish brown, mottled with reddish 

 brown; ovisac white, projecting 

 behind the coccid, broadly oval 

 and convex, with the cottony 

 secretion forming three distinct 

 parallel ridges behind her. Im 

 mature female, semi-transparent 

 to yellowish green, oval convex, 

 broadest in front, • the outer 

 margins finely crenulated. Male 

 puparium semi-transparent, white, 

 forming a regular elongate box, 

 the sides angled and the dorsal 

 surface flat, the front sharply 

 acute. Length, .^q inch. Allied

to Pulvinaria dodonaw, but the 



structure of the male puparium is very diffcicnt.
