Bureau of Entomology collection possesses a few specimens taken 

 from the roots of grass, Yorke Peninsula, South Australia, collected 

 by A. Koebele, which from a careful comparison with Maskell's speci- 

 mens appear to be the same species, and owing to the unsatisfactory 

 condition of Maskell's mounts, some of the description and the figures 

 given below have necessarily been taken from the South Australian 

 specimens. 



Adult female. — Body strongly convex, wrinkled, dark reddish 

 brown, etc., as described by Maskell; derm clearing after treatment 

 with potassium hydroxide; antennae small and short, 6-segmented; 

 legs much reduced, semi-rudimentary, the joints very indistinct, the 

 claw stout and short, both pairs of digitules present, slender, 

 knobbed; spiracles large, stout and heavily chitinized, considerably 

 more developed than in the normal coccine forms; mentum very

short and broad, small, 1-segmented ; derm with tubular ducts, large! 

 and small, scattered rather uniformly throughout, and ventrally with 

 multilocular disk pores, all of approximately one size, normally with 

 about seven loculi, but variable, as shown in figure, in transverse 

 rows anterior to the anal plates, with pores of similar size, but 

 normally quinquelocular, in rather heavy bands between the spiracles] 

 and the margin, dorsally anterior to the anal plates with some cir- 

 cular indistinctly trilocular disk pores ; marginal setae stiff, tapering, 

 entire, rather long, scattered and not in a single row in one plane! 

 and sometimes two deep, not continuous clear up to the spiracular 

 spines; the latter short, stout, somewhat clavate, with one, or rarelyJ
