tip shorter, and a spine on either side, with the same slender anal 

 filaments. 



Hab.—I'ort Macquarie, N.S.W, Larvje found in galls growing 

 upon the "swamp mahogany" [Eucalyptus rohusta) in September 

 (Mr. G. R. Brown); Southport, Queensland. The gall was 

 collected by myself in May, upon Eucalyptus sp. 



Brachyscelis sloaxei, n.sp. 



(PI. VIII., figs. 2-4.) 



5. Gall slender; 2^ inches in length, 6 lines in diameter in the 

 centre, at the base and apex 3 lines. When young greyish-green, 

 matured galls dull brown; cylindrical, tapering at the extremities, 

 apex truncate with the centre produced into a small projecting 

 nipple, bearing a minute anal orifice at the tip. Gall-chamber 

 cylindrical, tapering to a fine point at the extremities, much 

 longer than the adult coccid, which is generally found in the 

 upper half of the chamber with the anal appendages close to the 

 apical orifice. The texture of the gall is peculiar, being formed 

 of three layers of vegetable tissue, the outer one slightly ridged 

 or ribbed, and the inner one smooth and shining. Growing singly 

 upon the smaller twigs, and variable both in length and thickness, 

 but all with the same typical cylindi-ical form, though sometimes 

 the gall is quite cylindrical and of the same diameter from base 

 to apex, yet at the other end of the series the base may be slender 

 and the gall very much thickened in the centre. 



2. Coccid 1 inch in length, very slender, the last abdominal 

 segment w4ih the anal appendages combined f of an inch long. 

 Cephalic segment dark orange, flattened on the summit, the centre 

 circular marked with a ring of shallow depressions round the 

 edge; thoracic segments corrugated at the apex : first to fourth 

 abdominal segments cylindrical; fifth cylindrical with a transverse 

 row of fine spines along the apical margin; sixth and seventh 

 longer, more slender than preceding ones, fringed with fine spines; 

 eighth longer than the rest of the preceding segments combined, 

 lightly covered with fine spines; anal appendages black, close
