South Wales, and at Mount Tambourine, and other localities, in 

 South Queensland, it has, in addition, in mature specimens, a 

 strong black tip to the wings. In D. hybrido'ides, the black is not 

 truly apical, as in this form of D. lestoides, but it is a broad prse- 

 pterostigmatic band, though, in very mature specimens, a certain 

 amount of obfuscation supervenes between it and the tip of the 

 wing. Both sexes of D. hybrido'ides are of much slenderer build 

 than D. lestoides; the abdomen is longer and narrower; the wings 

 also longer and narrower, and the appendages of the male very 

 different, and easily distinguished by the very sharp upcurved tips, 

 and conspicuous inferior spine of the superior appendages. The 

 female is distinguished also by its very dark head, with scarcely 

 any brown epicranial pattern, and by the very long and slender 

 wings. 



Hab. — Kuranda, N. Queensland. I have received a good series 

 of six males and one female, taken by Mr. F. P. Dodd, during 

 December, 1912.
