The coccids were found on the stems of the malle gum {Eucalyptus dumosa) 

 at Mildura, Victoria. They burrow under the surface bark, and form circular 

 convex blisters about one-eighth to one quarter of an inch in diameter ; the 

 portion of the cavity smooth, the bottom covered with white secretion. 



Adult female yellow, circular, resting in the centre of the cavity ; dorsal 

 surface very variable in form, usually flattened, with a central brownish 

 boss. Diameter about one twenty-fourth of an inch. Antennae almost 

 obsolete. Legs wanting; no anal tubercules, and the anogenital ring simple, 

 without hairs. Epidermis showing no spinneret orifices.

This coccid is found upon the twigs of an undetermined species of Casuarina 

 growing on the Swan River, Western Australia. The adult female coccids 

 congregate together, forming a regidar sear in the bark, and are enveloped 

 in a white woolly secretion; they somewhat resemble a colony of woolly 

 apliis on an apple tree. 



Adult female green, globular, covered with scales of white wax. The 

 epidermis covered with spinnerets, and sHghtly protruding pores. Antennae 

 wanting, represented by small chitenous spots. Legs wanting. Cast skin 

 of larval stage often covering the adult.
