fascicles small, situated far apart, almost at extreme margin of

 mm. 



Hah. — New South Wales: Goulburn, Yass, Gunning, Shoal-

The identity of this species is unfortunately somewhat open to 

 dispute, as I cannot say with certainty that the type has been 

 examined. Under the label of P. ahnormis, in the Macleay 

 Museum, there is only a female, while the pair in the Australian 

 Museum bear the locality Monaro. Macleay, in his paper, 

 described P. ahnormis as from Argyle, and the species described 

 above is from that locality; furthermore, I have found, among 

 the Macleay duplicates, a specimen bearing the name P. ahnormis 

 in Macleay's handwriting. This species extends along the 

 southern highlands, but in Monaro its place is taken by two 

 other forms, both at present undescribed; one is the pair above 

 mentioned, in the Australian Museum; and the other has been 

 th^ought to be P. d'Urvillei; pending investigation into the 

 identity of the latter, I have described neither as new. 



P. ahnormis is replaced, further to the west, by P. assimilis.
