SYNONYMICAL NOTES ON SOME RECENTLY 

 DESCRIBED AUSTRALIAN CICADID.E. 



By W. L. Distant. 



(Communicated by W. IV. Froggatt, F.L.S.) 



Since Goding & Froggatt published their monographic revision 

 of the Australian Cicadidae, the path has been cleared for other 

 workers in that continent. Mr. Howard Ashton has recently 

 published descriptions of new species; but, as a large proportiijn 

 of these have been previously described, I am sure Mr. Ashton 

 will be glad to have these errors corrected.

My reasons for regarding A.jiava Asht., as a synonym of A. 

 interclusa Walk., are as follows. Ashton's description accords 

 with Walker's type, from which he says it differs " in its lighter 

 colour, smaller size, less produced front to head, powdered white 

 penultimate segment, and unspotted tegmina." The measure- 

 ments given b}^ Ashton, represent those of Walker's type; the 

 head is not le.ss produced (judging by A.shton's figure); A. inter- 

 clusa has the anal segment powdered white, and also the tegmina 

 unspotted. 



Ashton's figures are somewhat difficult to reconcile with his 

 description; he gives the expanse of tegmina as "90 mm.," which 

 agrees with that of Walker's type, but his figures expand, J" 110,
