This genus is defined by Cockerell as a Dactyhpid with the anal ring with- 

 out hairs ; adult female with legs and antennae ; the latter well developed, 

 cylindrical, six-jointed, the last joint long. It was created to contain a 

 remarkable coccid that Maskell described Under the name of Coccus acacice.

This curious coccid conies from near Perth, Western Australia, upon an 

 undetermined small thorny acacia. 



Adult female dark red, with yellowish tints, semi-globular, segmented and 

 wrinkled. Diameter, about yV of an inch. 



Antennse composed of six joints, sixth longest, the third large, the rest of 

 the segments short and of about equal length. The feet long, tibia slightly 

 longer than the tarsus ; all the digitules fine hairs. The anal tubercles very 

 small. Anogenital ring small, simple, withovit hairs; margin without spines 

 or hairs ; the epidermis showing very few circular spinnerets. 



Maskell described this species from dead specimens. Fuller in his de-
