49. T. iacchus, Fabr. 



Papilio iacchus, Fabr., Ent. Syst., p. 533, 1775; Donovan, 

 Ins. New Holl., pi. xxxi., fig. 1, 1805. 



The description formerly given by us, T. iacchus, Fabr., 

 refers to eliena, Hew. The whole trouble arose thus : Herrich- 

 Schaffer recognized that Hewitson's eliena was allied to 

 iacchus, but not knowing true iacchus says (S.E.Z., p. 80, 

 n. 66, 1869): — 'Teh bestimmte dies Thier vor Herrn Hewit- 

 son's Erklarung als H. iacchus, Don., Austral; es sind in 

 diesem Bilde die Flecke der V 11 nur gar zu licht und jene 

 der U.S. der H fl zu gross weiss gekernt," indicating that he 

 disagreed with Donovan's as representing iacchus. Plbtz no 

 doubt considered Herrich-Schaffer's figure of eliena and Dono- 

 van's were not the same, and imagined that Herrich-Schaffer's 

 incorrectly determined Hewitson's eliena, and so considered 

 the figure to represent donnysa, Hew., and placed eliena, 

 Hew., as a synonym of iacchus. The original Fabrician 

 description reads: — "Papilio iachus; alsi ecaudat'is, flavo 

 maculatis postis punctus sex niveis" (wings without tails, 

 spotted with yellow and six snowy- white dots). The number 

 of spots should be five, not six, although Donovan's figure 

 shows seven, caused by the veins dividing two of the spots. 

 Mr. R. E. Turner states that the type iacchus which is in the 

 Banksian Collection has the spots somewhat more elongate 

 than usual, and although neither iacchus nor eliena can be 

 said to possess white spots on forewings, those on iacchus are 

 yellowish- white and those of eliena golden-yellow. I am quite 

 satisfied that the northern form, ranging from Brisbane to 

 Cape York, is iacchus; and the southern form, ranging 

 through New South Wales, Victoria, South Australia, and 

 Tasmania, is eliena, Hew. Professor Mabille, to whom speci- 

 mens were submitted, returned them as phigalia, Hew. ; cer- 

 tainly an error in identification.
