SCALE INSECTS (" COCCID^ ") OF AUSTRALIA. 21 



of the five parallel sections coalesced together, which compose the gall ; 

 these tips, being bract-like, and covering the apical orifice. The whole of 

 the outer surface of the gall thickly clothed with a uniform coat of greyish 

 down, hiding the sectional structure, except at the a])ex. Variable in size, 

 up to one inch in height, and five-eighths of an inch in diameter in the centre. 

 The internal structure is solid, with a central hard smooth-walled circiular 

 chamber running from the base to the apex. 



The adult female reddish, elongate, cylindrical, truncate at the head, with 

 the tip of the abdomen rounded, clothed with fine hairs ; viewed from the 

 dorsal surface it shows several segments, of which the first three are largest, 

 with rounded posterior lobes ; median segment short and concave, imder 

 which the larvae shelter; the last abdominal segment forms a circular plate, 

 with a simple hairless anal orifice in the centre. Antenna? present but short, 

 conical, coming to a point. Legs present, first pair very short and thickened, 

 the second and hind pair aborted, only represented by dark spots. 



Maskell's galls were apparently old and nmch rubbed, and in his plate 

 do not show the curious calyx, but in a co-type he sent me many years ago 

 this is present, and there is no doubt this is his species.

This species is found in Victoria upon Casuarina quadrivalvis . I have not 

 seen it from any part of New South Wales.
