parts widely separate; tips rather thick and blunt, upcurved; 

 yellowish-brown. 



9. Yery similar to (J, differing as follows : — Ahdome7i broader, 

 more cylindrical, less clubbed; 2 with a large diamond-shaped 

 dorsal yellow spot; no spurs; 10 dull olive-green, short, projecting 

 below between appendages. Appe7idages short, about 1 mn),, 

 subcorneal, wide apart, parallel, bluntly pointed, yellowish; the 

 projection of seg. 10 appearing as an olive-coloured tubercle 

 between them, and nearly as long. 



H a b. — Kuranda, N.Q.; December-January; local. 



This species appears to be confined to a small area on the 

 ranges about Kuranda. It does not occur higher up at Atherton, 

 and below the range I took only isolated specimens. 



It is abundant along the sandy banks of the River Barron, 

 where I took it resting high up on the bushes and small trees 

 along the river bank. It never appears to settle on the ground, 

 but a dozen or more might often be seen resting on one small 

 tree. When disturbed it generally flies off with the wind to 

 another tree. It is also fond of flying in and out about the trees 

 on warm still days. 



Note. — M. Rene Martin informs me that there is in the 

 collection of Baron de Selys-Longchamps a specimen, undescribed, 

 but named A. proselytus, which he considers identical with this 

 species; locality uncertain, but supposed to be Queensland.
