BY A. SIDNEY OLLIFF, F.E.S. 405 



a few Queensland species, and I have to thank Professor Ralph 

 Tate of the Adelaide University, for a small number of specimens 

 named by M. Fauvel as well as for permission to describe one or 

 two new forms from the entomological collection which is under 

 his charge. Besides these materials I have examined the extensive 

 collections in the Macleay and Australian Museums, the latter 

 containing the types of the species from Gayndah, described by 

 Mr. Macleay, as well as the specimens collected by myself in the 

 Blue Mountains, in Tasmania and in the immediate vicinity of 

 Sydney. 



Whenever I possessed well-authenticated specimens of a species 

 I have redescribed that species. In not a few cases, however, 

 where no specimens have been available for examination, or where 

 the species have been identified from books, I have, in order to 

 avoid confusion, taken the description from a previous author, 

 usually that of the original describer, appending his initials in 

 acknowledgment. 



Family STAPHYLINID^. 



Maxillae of variable form and structure, with two lobes, usually 

 ciliate, the external often bi-articulate ; maxillary palpi 4-jointed, 

 except in Aleochara and Correa where there is a minute fifth 

 joint. Mentum more or less corneous, transverse or quadrate, the 

 anterior part separate. Ligula generally membranous, very 

 seldom corneous. Paraglossia usually distinct and in some cases 

 very conspicuous. Labial palpi usually 3-jointed, sometimes (in 

 certain Aleocharinse) with one, two or four joints. 



Eyes lateral, except in the Steninse, usually finely granulated. 

 Ocelli or simple eyes exist in the Homalinas. 



Antennae 11, rarely 10-jointed, variable in form, but most 

 frequently filiform and shorter than the body ; sometimes clavate 

 or thickened towards the tip and in a few instances distinctly 

 clubbed. 



Prothorax variable in form ; the side-pieces not separate ; 

 coxal cavities usually open behind. Mesosternum and meta- 

 sternum with the epimera distinct, the side-pieces of the latter 

 narrow.
