metathorax downy, shiny brownish-black above, dorsal ridge 

 bright yellowish-brown; on each side a semi-obsolete brown ray; 

 sides of thorax glaucous olive-brown. Legs brown, elbows and 

 tarsi black. Abdomen cylindrical, not constricted at 3; 2 

 with very small dark brown spurs. Colour dark brown, 

 glaucous. Appendages: superior very remarkable; long, 

 4 mm., separated at bases, basal two-fifths slightly divergent, rest 

 narrower, bent suddenly inwards so as nearly to meet at tips, and 

 tapering to a blunt point; hairy, semitransparent brown. Inferior 

 2-4 mm., narrow, subtriangular, upcurved, pale transparent 

 brown. (See Plate xxi., figs. 7, 8). 



£. Unique (immature), similar to £; wings slightly larger and 

 much more suffused with brown; abdomen flabby, cylindrical, 

 wider than in ^; end of 10 forming a rounded hairy tubercle 

 separating the short (1 mm.) conical dark brown appendages. 



Rob. — Endeavour River, near Cooktown, N.Q. Two males and 

 one female; January, 1908. 



I found this species invariably settled in trees, from 10 to 20 

 feet from the ground. When disturbed it flies off and makes for 

 another tree. It is easily captured, unless too high up to be 

 reached. I never saw it indulging in continuous flight, but the 

 specimens I took were not fully matured, and the weather was 

 unfavourable.
