Two $?, one of which is immatitre, from the blue-bellied lorikeet 
(Trichoglossus novae-Jiollandi'ae), Myall River, New South Wales, I pro¬ 
visionally assign to this species. These show some differences, which 
may be real, or may be due to the marked difference in the state of 
preservation. I figure the adult $ (Fig. 14), as well as the head, and 
the occipital apodemes (Text-fig. 3). The main differences lie in the 
darker coloration of the pleura and all lateral bands; the better defined 
transverse bands of the abdomen, with stigmata prominent in light- 
coloured areas; the inner row on the metathoracic border containing 
two, not three, hairs; and the pencils of hairs on the ventral surface 
of the ninth segment being so short as not to project beyond the borders 
of the segment. The measurements of this ? are also slightly larger, as 
the following table shows;
