in consequence, I think, be justifiably used in the sense intended. 

 The plant will therefore in future be known as Blechnoxylon 

 talhragarense. 



The fossils are associated in the same deposit with leaves of 

 Glossojjteris, and stems of our characteristic Coal Measure Conifer, 

 Bracliyphyllum. 



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 Bleclinum, Strangeria, and other plants. 



DESCRIPTIONS OF TWO BEETLES FROM :\IOUNT 

 KOSCIUSKO. 



By W. J. Raixdow, F.L.S., Entomologist. 



In working over the collection of Australian Carabidje contained 

 in the cabinets of the Australian Museum, I came across two 

 species apparently undetermined — one a Percosoma, and the other 

 Notonomus, sp. These arc, therefore, now described. 



Some time ago, Mr. T. G. Sloane described the Australian and 

 Tasmanian forms of the genus Percosoma as known to him.* Of 

 these P. tnontanuin, 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. careiioides, White, and P. sulcipenne, Bates, were from 

 Tasmania. The four species here enumerated comprised all that 

 was known of the Australian Percosoma 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 (Percosom.a) herein described, 

 I have been courteously assisted by Mr. Geo. Masters, Curator of
