SCALE INSECTS (" (JOCCIDiE ") OF AUSTRALIA. 5 



Adult female dark yellowish bro\v}i ; about one-tenth of an inch in diameter ; 

 circular in form, with legs and antenna? projecting when mounted in potash. 

 Antennae stout ; terminal joint rounded, surmounted with fine hairs. Maskell 

 says six-jointed, live specimens show only five, but there may be a sixth; 

 three pairs of legs, the first two pairs small, hind pair large, thickened ; tibiae 

 long, swollen to the tips ; tarsus cylindrical, first joint long, second short, 

 with no true tarsal claw, but bearing two slightly thickened digitules. Anal 

 ring distinct, showing no hairs. Hind margin of dorsal surface fringed with 

 dark brown spines, the central eight in contact at the base, the dorsal surface 

 clothed with scattered dark spines and fine hairs, thickest on the anterior 

 portion ; the whole surface' granulated with irregular oval tesselations, not 

 in contact with each other. Live specimens, when extracted from the galls, 

 look very much like minute crabs, the short stout antennae standing out on 

 either side of the head, with the hind margin of the abdominal segments 

 turned upward, and the swollen hind legs projecting on the sides. 



Speciriiens examined from Kurnell showed that the female produces some 

 white meal or filaments. The anal spines were not so well defined in the 

 anal comb ; structure more open at the base, but comprising about twenty 

 instead of eight, while the hairs fringing the outer margins of the coccid are 

 very fine and soft.
