the others decreasing in size to the outermost, which is always small and sometimes

 backwards. Derm with numerous small circular pores and some minute spiniform 

 hairs. Anal ring with six slender setae. Antenna (fig. 3, b) G-jointed, the 6th much 

 the longest, 5th shortest, the remainder subequal. Limbs small but robust. Foot 

 (fig. 3, c) with a stout falcate claw ; tarsus equal in length to tibia. Length of 

 complete insect 2-75 to 3-0 mm. Breadth (under compression) 2-25 to 2*50 mm.

and of indefinite form. Tarsus unusually long, at least one-and-a-half times as 

 long as the tibia (fig. 4, d), with a deep incision at about one-third of its length from 

 the distal end, which gives the tarsus the appearance of being two-jointed. Anal 

 lobes (fig. 4, b) large, stout and prominent, densely chitinous and strongly ^vl■ink!ed, 

 ^vith two small spines on the inner edge and a comparatively short stout seta at the 

 extremity of each lobe. Derm without spines, but thickly set with small irregularly 

 oval chitinous lenticels which appear to be arranged in roughly concentric series. 

 Anal ring with eight stout setae. Length, 2-0 to 2*50 mm. 

 Victoria : Sandringham, on slender twigs of Casuarina (C French, No. 113, a).
