Brachyscelis sessilis n.sp. 
(Plate xix., fig. 2.) 
£. Gall forming a rounded or oblong swelling on the branch, out 
of the centre of which springs up a tubular gall from 2 to 4 lines 
in height above the excrescence on the branch; 4 lines in diameter 
and perfectly flat on the truncated apex, with the exception of the 
small cone-shaped projection in the centre, encircling the minute 
apical orifice. The walls of the galls are stout and solid, containing 
a chamber rounded at the base and pointed towards the apex; 
each of these galls is distinct from the large swelling upon the 
branch from which they project, and can be detached without 
breaking. 
Q. Coccid dull yellow, 4 lines in length, broad and round at 
apex, central lobe with two very small antennae and short fore- 
legs, the second pair rather large, with the hind pair largest, the 
first joint swollen and almost globular; the last thoracic segment 
broad, the first four abdominal ones regular, and tapering sharply 
to the tip, the anal segment, bearing the anal appendages, rounded. 
Dorsal view, head, and thoracic segments covered with very fine 
scattered tubercles, but bearing no regular spines; first abdominal 
segment with short irregular black spines along the apical margin, 
on the second segment increasing in numbers and regularity until 
on the last two forming a close regular ridge of stout black spines; 
anal appendages black, very short, broad at the base, conical and 
almost in contact at the base until near the apex, opening into a 
V-shaped angle; the whole coccid lightly covered with hairs, 
thickest towards the extremity of the abdomen. 
(J. Gall and coccid unknown. 
Hab. — Wallsend, near Newcastle. On a small rough-barked 
Eucalyptus sp.
