in consequence, I think, be justifiably used in the sense intended. 
The plant will therefore in future be known as Blechnoxylon 
talbragarense. 
The fossils are associated in the same deposit with leaves of 
Glossopteris, and stems of our characteristic Coal Measure Conifer, 
Brachyphyllum, 
Throughout this enquiry I have been very ably assisted by my 
Colleague, Mr. T. Whitelegge, and desire to take this opportunity 
of expressing my thanks not only to him, but also both to Mr. 
E. R. Waite, who has spared no pains to render the illustrations 
accurate and intelligible, and to Mr. J. P. Hill, B.Sc., of the 
Biological Laboratory, Sydney University, for the loan of micro- 
preparations of Blecknunt, Strang eria, and other plants. 
DESCRIPTIONS OF TWO BEETLES FROM MOUNT 
KOSCIUSKO. 
By W. J. Rainbow, F.L.S., Entomologist. 
In working over the collection of Australian Oarabidse contained 
in the cabinets of the Australian Museum, I came across two 
species apparently undetermined — one a Percosorna , and the other 
Notonomus , sp. These are, therefore, now described. 
Some time ago, Mr. T. G. Sloane described the Australian and 
Tasmanian forms of the genus Percosorna as known to him.* Of 
these P. montanum , Casteln., and P. concolor, Sloane, were 
recorded from Victoria ; the former from Yarragon, Gippsland 
(Sloane), Dandenong Ranges (French), and the latter from 
Marysville District (Track to Yarra Falls, Best). Two others, 
P . carenoides , White, and P. sulci penne , Bates, were from 
Tasmania. The four species here enumerated comprised all that 
was known of the Australian Percosorna up to the date of the 
publication of Mr. Sloane’s paper, and from then until now, no 
further additions to our knowledge of the native species of this 
genus have been made. 
In the working out of the species ( Percosorna) herein described, 
I have been courteously assisted by Mr. Geo. Masters, Curator of
