460 A REVISION OF THE STAPHYLINID^ OF AUSTRALIA, 



If I am correct in my indentification of this species it is very 

 nearly allied to Aleochara haemorrhoidalis. It is pitchy black in 

 colour, less strongly punctured (except the abdominal segments 

 which are rather more strongly punctured) and the base of the 

 antennEe and anterior, and in some individuals the intermediate and 

 posterior, legs are i^eddish testaceous ; the antennas in the specimens 

 before me do not appear to aflord any distinctive characters. 



70. Aleochara Mastersi. 



Aleochara Mastersii, Macleay, Trans. Ent. Soc. N.S.W. II., 

 p. 136 (1871.) 



Elongate, rather narrow, moderately convex, dark piceous, 

 shining, finely and not very closely pubescent ; elytra finely rugose- 

 punctate ; 6 th abdominal segment narrowly margined with 

 testaceous ; antennae and legs dark reddish testaceous. 



Head finely and rather closely punctured. Antennae similar in 

 structure to those of A. haemorrhoidalis, the three basal joints 

 paler than the others, the apical joint sharply pointed. Prothorax 

 strongly transverse, considerably narrowed in front, strongly 

 margined behind, finely and closely punctured, sparingly clothed 

 with fine fuscous pubescence especially near the sides, the 

 anterior and posterior angles obtuse. Scutellum very small, 

 finely punctured. Elytra transverse, slightly shorter than the 

 prothorax, finely rugose-punctate, moderately closely pubescent. 

 Abdomen rather long, narrowed posteriorly, strongly and not 

 very closely asperate-punctate. Length 6 mm. 



Gayndah, Queensland. A single specimen. 



Closely allied to Aleochara brachialis which it resembles in 

 having the antennas and legs of a reddish testaceous colour. It 

 is narrower and rather more attenuated posteriorly, is more finely 

 punctured and has the abdomen of a shining black colour with 

 the exception of a narrow testaceous basal margin to the sixth 

 segment.
