Adult female black, lightly covered with mealy wax, oval, rounded, seg- 

 mental divisions well defined, under-surface flattened. Length, | of an 

 inch. Antennfe eight- jointed, the last two (if distinct segments) broadly 

 rounded and much longer than the sixth and fifth combined; first short, 

 broad ; third slightly longer than the fourth and fifth. Legs long, femora 

 stout, tibia slender, tarsus fine, curved in at the tip. Anal tubercles very 

 small with one long spiny hair and half a dozen shorter ones. Epidermis 

 very thickly covered with circular spinneret orifices, and stout hair-like 

 spines springing from distinct tubercles.

This scale was found upon an introduced plant, one of the African heaths 

 (Erica autumnalis), at Melbourne, Victoria. It may therefore not be a 

 native of Australia. I have no other record of the species. It generally 

 secretes so much honey-dew that all the foliage of the infested plant becomes 

 smothered with fumagine ; the type specimens were also hea\Hly parasitised 

 by chalcid wasps. 



Adult female varying in colour from dark brown to red; general form 

 subglobular; aggregated masses of dirty white cotton surrounding but not 

 covering the coccid. Length of coccid, ttV of an inch. Antennse consisting 

 of seven joints, last one longest. Feet moderate ; digitules fine hairs. Anal 

 tubercles very small; anal ring with six hairs. Epidermis ver}- finely 

 wrinkled, bearing spinnerets and conical spines. 



Maskell further says : " It comes nearest to Dactylopius glohosus (Mask.) 

 from which it difters in not being covered by its cotton, and in the characters 

 of the epidermis."

A species found upon the foliage of Grevillea hiipinnatifida at Swan Eiver, 

 Western Australia. 



Adult female stationary, subglobular, distinctly segmented, lightly 

 covered with mealy secretion, and enclosed in an almost perfect spherical 

 sac. General colour, purplish black ; antennfe seven-jointed. Legs short and 

 stout. Epidermis wath many spinnerets and small spines; tubercles small, 

 each with one long spine and four smaller ones ; similar spines on the sides 

 of each segment, and a row across the back. Anal ring with six short hairs. 

 Size not given by Fuller.
