NOTES n\ PLIES HARDY. 35 



01)!^. — Specimens from Cradle Mountain differ from tliose from 

 Mount Wellington in the markings of the thorax, the colour of some 

 of the hairs, aud also in other small details. The Cradle Mountain 

 specimens have been designated P. niontanns var. a. by me (Lor. cif., 

 1918), but it is probable that they will be found to merge into tlie typical 

 form when material is available from other localities for comparison. 



Tijpes. — The holotype and allotype of the typical form and also the 

 holotype and allotype of the var. a. are in the Australian Museum.

Synouymy. — Miss Ricardo definitely states that Walker's type of 

 Silvius perxoiHitus is identical with Macquart's genotype P. nutCKlipciuiia, 

 but although Walker's name has priority she has used Macquart's name 

 in prefei'ence, and in this has been followed by all subsequent 

 entomologists. 



The species has not been satisfactorily recognised in Australian 

 collections but undoubted!}' Sydney specimens and Sti-adbroke Island 

 specimens belong here. A specimen from the latter locality is in the
