to Psalidttra, and probably to the P. impressa-gvouip, if indeed 

 it does not prove to be that species. 



Bohemann, in 1843 (Sclionh., Gen. Cure, vii.(l)) published 

 descriptions of Amycteridce, five of which have been placed in 

 Psalidura — P. d'Urvillei, P. Ilojyei, P. iriira, P. Spencei^ and P. 

 squalida. Of these, P. mira is a member of the horned -jaw 

 group, and is most probably the species so considered by Macleay; 

 its locality, however, is not Swan River, as recorded by Macleay, 

 but Sydney. P. d'Urvillei and P. squalida, being founded on 

 female specimens, cannot be recognised with certainty, except by 

 examination of the types. P. Hopei should, I think, be referred 

 to SclerorrhinuSy on account of the following passages in the 

 description : — " linea frontali laevi, usque ad apicem rostri con- 

 tinuata silaceo-marginata; . . . ; rostrum . . . supra 

 late sed parum profunde bicanaliculatum." P, Spencei I cannot 

 recognise, but I do not believe it to be assignable to Psalidura, 



In the Transactions of the Entomological Society of New South 

 Wales (Vol i., 1865, p 200;, Sii- William Macleay reviewed the 

 genus, and added twenty new species — P. abnor'mis, P. caudata, 

 P. Coxi, P. elongata, P. falciformis, P. forjiculata, P. foveata, P. 

 Helyi, P. Howitti, P. Master si, P. miractda, P. mirijica, P. 

 Mitchelli, P. montana, P. riifolineata, P. squamigera, P. subcostata, 

 P. subvittata, P. verimcosa, and P. Wilcoxi. Of these names, P. 

 Ilelyi and P. Howitli are synonyms of P. impressa; P. mirijica 

 I have placed as a variety of P. mira Boh.; while P. rufolineata, 

 though in the present paper maintained as distinct, may come to 

 be regarded as a variety of P. mirabilis; in some respects P. 

 reticulata, which I have united with P. mirabilis, seems inter- 

 mediate between the two species. 



P. decijnens Dohrn, 1872. — I have seen no Psalidttra small 

 enough to fit the description of this species; tentatively it might 

 be placed near P. Wilcoxi. 



Since the date mentioned, no new species of Psalidura have 

 been described, and although the name P. mannerheimi Schon., 

 (Schonh., Mant. Sec. p.55) appears in Masters' Catalogue, it is a
