186 Arthur M. Lea : 



bined, second very little longer than third, third to tenth sub- 

 equal or very feebly increasing in leng-th, eleventh as long as 

 ninth and tenth combined. Prothorax slightly longer than 

 wide, rounded at apical third, with sides strongly diminishing 

 in width to apex, and gently to base ; base with a feeble trans- 

 verse impression ; with minute, scattered punctures. Elytra 

 oblong-ovate, at base scarcely wider than base of prothorax, 

 rapidly increasing in width to basal third, thence gently 

 rounded to apex ; base gently conjointly arcuate and without 

 depressions ; with sparse but, for the genus, fairly distinct • 

 punctures. Legs long ; femora clavate ; tibiae somewhat 

 thickened about basal third, then slightly narrowed. Length 

 2 mm. 



Hah. — Victoria : Geelong, in a nest of Iridomyriiiex nitidus 

 (H. W. Davey). 



I have not been able to examine the labial palpi of the type, 

 and the species may eventually be regarded as belonging to a 

 new genus, but at present I think it is best referred to 

 Scydmaenus. At first glance it rather strongly resembles an 

 Anthicus. 



From some directions the extreme elytra! margins appear 

 reddish. The abdomen is strongly notched at apex, the notch 

 fringed with tine pubescence ; but this is probably a male 

 characteristic. All the tibiae are thickened about the basal 

 third, but the middle pair less noticeably than the others. 



Scydmaenus ojytatus, Sharp. 



In the original description of this species no mention is made 

 of an impression between the antennae ; but on seven specimens 

 from W. Australia before me such an impression is quite dis- 

 tinct. The species is readily identifiable by its two jointed 

 club, with the ninth joint more than twice as long as wide, and 

 about as long as the two preceding combined. 



Sharp simply records it from West Australia. I have taken 

 it at Swan River, Newcastle, and Donnybrook, and in the nests 

 of Camponotus dorycus and Ponera lutea. 



Two specimens from N.S. Wales (National Park — H. W. Cox —
