494: A REVISION OF THE STAPHYLINIDiE OF AUSTRALIA, 



Labrum transverse, bilobed, with a membranous border. Man- 

 dibles very strong, toothed on the basal half of the inner margin. 

 Head transverse, sub-orbicular, narrowed behind into a moderately 

 distinct neck. Eyes not very prominent. Antennae short, slightly 

 thickened towards the extremity; the basal joint long and sinuous, 

 the following joints short and gradually decreasing in length, the 

 terminal joint acuminate. Prothorax transverse, rounded behind, 

 truncate in front, with the anterior angles distinct and refiexed. 

 Elytra obliquely truncate at the extremity. Abdomen sub- 

 parallel. Intermediate coxee widely separated. Legs rather short, 

 robust ; the tibiae spined ; the tarsi moderately long, the anterior 

 pair strongly dilated, the intermediate and posterior pairs filiform, 

 with the basal joints rather longer than the three following ones. 



The division which I have here ventured to propose is very 

 nearly allied to CreopJiilus and Ocyj)us, but differs from the former 

 genus in having the antennae longer and more slender, the head 

 very broad, the elytra smooth and almost free from pubescence ; 

 from Ocypus it is distinguished by having the intermediate coxae 

 widely lemote. 



139. COLONIA REGALIS, Sp. 11. 



Pitchy black, shining, very robust ; prothorax narrower than the 

 head, the posterior angles rounded ; elytra dull black ; abdominal 

 segments tinged with green. 



Head very broad, obscurely and rather sparingly punctured on 

 the disc, more strongly punctured between the antennae, with two 

 setigerous punctures on the inner orbital margin of the eyes, and 

 another less conspicuous puncture near the base of each antenna ; 

 the sides regularly rounded. Antennae moderately robust, black, 

 joints 5-11 clothed with fine fuscous pubescence. Prothorax 

 slightly narrowed in front, very obscurely and not very closely 

 punctured, with a row of punctui'es on the anterior margin near
