Brewarrina, N.S. W.; one fine specimen (W. W. Froggatt leg.); 

 Coll. Froo-'^att. 



The species occupies an isolated position within the genus in 

 regard to the shape of its wings. 



Ceratoleon, n.g. 



Body ver\^ stout. Abdomen much shorter than the hindwings. 

 Vertex very raised. Antennae almost fusiform. Legs short and 

 very stout. Tarsi shorter than tibiae. Fifth tarsal joint the 

 longest; first joint not so long as second and third united; fourth 

 the shortest. No spurs. Costal area in the forewings with two 

 rows of cells in its basal third. In forewing, Rs arises at a level 

 much before that of the cubital fork; in the hindwing, one cross- 

 vein before origin of Rs. Veins 2 A and 3 A separate; in the 

 forewing, they are united with two cross-veins; in the hindwing, 

 with one. Banksian line present in both pairs of wings; inter- 

 cubital line distinct in the forewing. 



Genotype, Ceratoleon hrevicornis^ n.sp 



This genus is a very distinct one, easily recognised by the 

 peculiar shape of the antennae; and by the nervature of the wings, 

 which differs in many points from that in Austrogymnocnemia.
