It differs from the type as follows: — (1) Shorter jjterostiyma, 

 (J 2, 9 2-5 mm., that of ^ covering l|-2 cellules only. (2) Frontal 

 yellow spots comparatively close, 0-5 mm. apart in ^ and 1 mm. 

 in 9. (3) Colouration black or very dark brown with gold or 

 yellow markings; the colouration of the type-form is brown with 

 creamy markings. (4) A pair of distinct antehuyneral lines or 

 rays on thorax, gold or yellow, from 1'5 to 2-5 mm. in length. 

 These are not present in the type-form.

Very distinct from the type-form, but, in my opinion, not above 

 subspecific rank. Some of the females which I took at Ebor, 

 approach the type-form in size and colouration. It is of interest 

 to note that, on the Dorrigo Plateau, two of the species of Meta- 

 themis are replaced by new subspecific forms, while the third 

 species, M. virgula Selys, is exactly like the type-form. Syn- 

 themis eiistalacta Burm., and S. macrostigma orientalis Tillyard, 

 also occur on this plateau, and are of typical form.

A single male taken by Mr. F. P. Dodd at Kuranda, N.Q., 

 November, 1906, was described by me in these Proceedings 

 (xxxiv., p. 249), and the male appendages figured. At Pallal, 

 N.S.W. , in December, 1910, I found this species quite common 

 along the Horton Kiver. The males resemble the type very 

 closely, but are somewhat more brightly coloured, and of slightly 

 stouter build.
