The type speciiueiis were described from coccids obtained in the empty 

 oalls of a gall ('octid (Apionwrpha maliformis) on a eucalypt. 



Adulb female globose, forming a thick white com])act convex sac measuring 

 0-2 inch in length. 



AntenniX" composed of seven joints, the second, third, and fourth subequal. 

 seventh smaller, but longer than fifth and sixth. Legs slender, tarsus longer 

 than tibia, upper digitules knobbed, lower ones fine hairs. Anal tubercles 

 small cylindrical, apex almost truncate, terminating in a long seta ; two spines 

 at base, and one on the lateral margin. Anal ring with eight hairs. Dorsum 

 with many small acuminate sjtines with a marginal fringe of large spines 

 arranged at regular intervals.

Specimens scattered over the foliage of the Norfolk Island Pine {Aimicaria 

 exceha) collected at Perth, Western Australia, by Mr. J. L. Newman. 



Adult female forming a broad, rounded, slightly-flattened, but convex 

 white sac, formed of thin, rather soft white cotton secretion, with no distinct 

 anal opening. Length up to \\ of an inch. 



Adult female yellow, when alive filling the sac. Antennjc rather long, 

 slender, composed of seven joints, second long, third much longer, fourth 

 short, fifth and sixth small, more oval in form, seventh small, rounded, hairy. 

 Feet long, slender, tarsus as long as tibia, digitules dilated at the tips. Anal 

 ring with eight hairs. Anal tubercles broad at the liase. sides straight with 

 angulated cleft on the outer margin below the tij) with a stout s])ine at base 

 and at cleft a similar spine on the inner margin and a slender seta at tip. 

 Derm with a marginal fringe of stout s])ines and the surface covered with 

 small circular spinnerets. 



At first I thought this was the typical E. araKCoiirp, but it seems quite dis- 

 tinct ; the difference in the antenna?, legs, fine spinnerets on the epidermis, and 

 the anal tubercles are very marked. While all the specimens of the typical 

 forms ontheAraucaria and Kunzia cover the foliage with black smut. the foliage 

 of the pine infested by this s[)ecies is perfectly clean and the sacs pure white.

This is the white scale ()f the Norfolk Island Pine {Aravcaria e.ael-a). and 

 is also found on other ]»ines of this genus. It was first recorded u]Jon trees 

 grownng at Canterbury. New Zealand, but it has s])read to other countries 

 with its food-plant, and is now recorded ficm ('cyloii, Sandwieh Islands, 

 South Africa, California, and Australia.
