This species was made the type of a new genus upon specimens found on 

 an undetermined leguminous plant at Birchip, Victoria. Though Green 

 points out in his " Note on the Genus Lecaniodaspis " that this generic name 

 cannot stand, it has generic rank in Mrs. Fernald's catalogue. 



The test of the adult female is corneous, semi-transparent, fulvous, formed 

 of brownish waxy secretion, through which the enclosed female can be S€en 

 at the anterior portion ; broadly oval or oblong, very convex, with numerous 

 transverse and four longitudinal furrows. Length, 1-25. 



The adult female is subcircular, joints of antennae indistinct, usually three, 

 second longest ; vertical orifice with many spinnerets ; anal ring with then 

 flattened hairs. 



The male tests are white opaque, rather broadly oval, with a circular 

 opening at the posterior extremity.

This coccid is found on the surface of the bark of the branches and trunk 

 of the Sassafras {Atherosperma moschata), growing near Fernshaw, Victoria. 



The adult female forms thick waxy tests on the bark which are not em- 

 bedded in pits ; convex, longer than broad, having a prominent dorsal ridge 

 with distinct transverse striations. The general colour is a dull reddish 

 brown. Length about i\~ of an inch. 



The adult female is dull red, fitting close into the test ; general form ellip- 

 tical, dorsal surface convex; antennae long, composed of eight uniform seg- 

 ments ; third longest, terminal one with hairs ; feet wanting, anal segment 

 produced into a pair of tubercules with a bristle ; margin of the body with 

 two small depressions containing spines. Epidermis covered with tubular 

 spinnerets springing from figure-of-eight orifices. Anal ring distinct, with 

 about ten stout hairs, surrounded with the anal plates. 



The male test is waxy, dark yellow, cylindrical, corrugated transversely, 

 with a flat plate on the anterior portion, through which the male emerges. 

 Length, -jV of an inch.

The female coccids massed together on the branchlets of an midetermined 

 species of eucalyptus growing at Picton, New South Wales. The specimens 

 were determined for me by Mr. E. E. Green. 



The test of female is a dull chocolate brown, but the surface is crossed with 

 very fine lines of white secretion in no regular pattern, except that there is 

 usually one forming a dorsal stripe, thin and paper-like but melting in caustic
