 This species has a wide range. The types were collected in an undeter- 

 mined eucalypt near Richmond, New South Wales. I have found it at 

 Wagga and at other localities on the red-gum {Eucalyptus rostrata), and at 

 Hay, New South Wales, upon a box-gum {E. hicohr). Fuller records it from 

 Swan River, Western Australia, on another gum-tree, and French from 

 Dandenong Range, Victoria, on E. regnans. 



The females infest the branches, which swell out into aborted masses of 

 tissue forming galls of all shapes and sizes, several inches in length, and 

 broad in proportion. In these irregular woody masses the true coccid galls 

 are embedded, usually hidden under the surface of the bark, but when the 

 rough, dead, surface bark is pulled off, the apical tip of the upper half of the

gall may be seen level with the surface or slightly projecting. The apical 

 half of the gall, though it appears to be first formed of the bark, as the galls 

 mature becomes a distinct funnel-shaped or conical cap, hard and solid with 

 a very small circular opening fitting close against the upper rim of the lower 

 half of the gall, which is a smooth white circular convex pit in the solid wood, 

 in which the coccid rests, the tails reaching into the cap. Diameter of pit 

 above, | inch; depth of pit, \ inch; the cap portion of gall, \ inch. There 

 are often three or four of the coccid gall pits in each woody mass, and the 

 trees are often covered all over the branches with these woody excrescences. 

 Adult female coccid diill yellow, with the apical abdominal segments and 

 legs reddish-brown ; the anal appendages black. Length, ^ inch. General 

 form elongate, turbinate, constricted at the apex of the thoracic segment, 

 tapering to the tip. Antennae and legs well defined. Dorsal surface covered 

 with fine scattered spiny hairs, very lightly upon the thoracic portion, but
