The sac of the adult female is oblong oval, about 3 nun. in length. (Ireen 

 says : " Colour and texture difficult to determine, every example being 

 thickly encrusted with black fumagine fungus, as is also the surrounding 

 surface of the bark. The inner coating of the sac is white." 



On the other hand, the male sac is snow-white, not affected by the fumagine.. 

 and about half the size of that of the female. 



Adult female oval, colour not recorded. Antenna? seven-jointed, the second, 

 third, fourth, and seventh longest. Anal tubercles stout, with short anal seta, 

 with a long spine at the base of inner side, a slender one on outer side, and two 

 slender ones at the apex. Anal ring with eight stout hairs. Derm with 

 slender pointed niarginal spines in sets of three, on the abdominal segments., 

 {laired spines on the back, reduced to a single pair on the abdominal segments, 

 with a smaller single spine on each segment between the outer and inner ones.. 

 Both the dorsal and ventral surface of derm with spinnerets and fine hairs. 

 Length, 1-25 to 1-75 mm. 



Green sa}s : " Differs from E. dant/ionice, Mask., in the broader form, 

 shorter marginal spines, and the presence of a median dorsal series. Near 

 E. leptosvenni, Mask., but differing in the single marginal fringe and seven- 

 jointed antenna^."

The type specimens collected upon the foliage of an undetermined species 

 of Eucalyptus at Oatley, near Sydney, New South Wales. 



The sac of the adult female convex, elongated and rounded at the ex- 

 tremities, composed close, felted; white filaments, htting close down on the 

 surface of the leaves. Length, about H inches. 



Adult female elongate oval, yellowish brown. Antenna^ composed of 



six joints, of which the third and sixth are the longest. Legs slender, tibia> 



a little shorter than tarsus ; digitules fine hairs. Anal tubercles narrow. 



cvlindrical, each bearing several short, spines and long terminal set?e. The 



epidermis covered with many circular spinnerets and fine hairs: the margins 



are irregularly fringed with stout blunt spines, each segment of the cephalic 



area with fourteen to sixteen, and each abdoniinal segment with five on 



each side. 



Sac of male coccid similar in form, but much smaller and more loosel}'

 This species was originally described from South Australia from specimens 

 collected by Mr. Crawford upon Eucalyjitus globulus and Busaria spiuosa.. 

 It has a wide range, as it has been found in Tasmania on Excalyptus vimi>wh'-<-
