SYNONYMICAL NOTES ON SOME RECENTLY 

 DESCRIBED AUSTRALIAN CICADID.E. 



By W. L. Distant. 



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



Since Coding ife Froggatt published their monographic revision 

 of the Australian Cicadidse, 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 proportion 

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

 will be glad to have these errors corrected.

My reasons for regarding A. flava 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 by Ashton, represent those of Walker's type; the 

 head is not less 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 1 10,
