The tj'pe is described from Europe upon the common shrul) Buxus semper- 

 virens. Signoret says that the sacs of botli luah^ and tVunaU' coccids are pure 

 white. The adult female rounded, oval. Antenn* composed of six segments, 

 the third segment longest, fourth and fifth shorter, sixth straight, as long as 

 the second, hairy. Dorsum covered with short tubular filaments of uniform 

 thickness and other scattered, pointed ones. Tibia as long as tarsus, claw 

 small, digitules large, thickened at the tips. Anal ring with eight hairs. 



Maskell has given our species the varietal name of Aiistrcdis. Specimens of 

 this variety are recorded from Manly, New South Wales, on a native shrub, 

 Tracliymotie billanlieri, from Grafton, New South Wales, on an undetermined 

 shrub, and from the Botanic Gardens, Brisbane, Queensland. 



The female sacs are usually on the under-surface of the leaves, of the typical 

 snow-white colour and elongate oval form, with the outer surface soft and 

 w^ooUy; about ,-u of an inch in length. Antenna; six-jointed, third longest. 

 The digitules all fine hairs. Maskell says : "I could perhaps mention a 

 number of very minute characters on which this insect differs from the type, 

 but the most important are the digitules not being dilated or knobbed, and 

 the marginal spines on the larvae being small instead of very cons])icuous, 

 as in E. haxi.

The type specimens were sent from Victoria thickly congregated together 

 upon the surface of the bark of EucalyjHus viminalis. I have specimens 

 thickly coating the inner layer of bark covered with a scale of dry bark taken 

 off the trunks of eucalypts in the park at Richmond, New South Wales, that 

 were determined by Maskell as this species. In these specimens the ovisacs 

 are flattened on the dorsal surface from the pressure of the dead bark, and 

 they are pure white. 



Maskell says : " Sac of adult female dirty white or grey, aggregated in 

 rough, irregular masses on the twigs (?) of the plant; loosely felted; the 

 normal form is globular, slightly elongated, length about %ro inch."' 



Adult female brownish yellow, sub-globiilar. Antenna? composed of six 

 joints, fourth and fifth shortest. Epidermis with many simple circular 

 orifices and long slender spines, with a few spiny hairs. Anal ring large, with 

 eight hairs.
