434 A REVISION OF THE STAPHYLINIDiE OF AUSTRALIA, 



palpi 3-jointed, the 2nd joint short. Maxillae with the interior 

 lobe provided with spines near the apex. Mandibles simple. 

 Head constricted behind into a narrow neck. Legs rather long, 

 slender ; tarsi 4:5:5, the posterior pair with the 1st joint elongate, 

 nearly equal to the four succeeding joints together. 



Allied to Tachyusa, but differing in the structure of the labial 

 palpi, labrum (which is rounded in front) and posterior tarsi. 

 The genus was founded on a species from the Mediterranean 

 region and has been recorded from New Guinea as well as from 

 Australia.
