588 ON THE GENUS DIPHLEBIA, 



Type (J, and cotype ^, in my collection, taken by Mr. F. P. 

 Dodd(December, 1907). 



This species can be distinguished, at once, from all other species 

 of the genus by the large inferior spine on the stiperior appendages, 

 also by the slenderness of the appendages towards the tips, and 

 their upcurvedness when viewed sideways. In colouration, it 

 resembles D. lesto'ides, but the shape of the abdomen is closer to 

 that of B. euphieo\des. The banding of the wings may also be 

 considered as intermediate between the narrow milky band of D. 

 lesto'ides and the deep, almost black, shading of D. euphwoides, 

 which nearly covers the wing. For these reasons, I have proposed 

 the name D. hyhriddides for this species. 



Owing to the excessive summer rains of the past few years in 

 North Queensland, no further specimens of this interesting insect 

 have been taken. But as the locality is now known, it is to be 

 hoped that the unknown female and less faded males will soon be 

 discovered.
