are obli(iuely truncated. Its metusternuin is strongly convex 

 along the middle. The length varies from 1^ to If mm. 



The ant in whose couipany it is taken appears to be a species 

 of Colobopsis. Mr. Davey has also sent the species from the 

 nest of a small black ant at Geelong (Victoria). 



ArticfTus hrevipes, Sharp. 



Described from a single female and as pi'obably from Cham- 

 pion Bay. Two females from N.W. Australia in the Macleay 

 Museum appear to agree with the description. 



Articerus curvicornis, Westw. 



The late Rev. R. L. King stated that he had frequently cap- 

 tured this species at Liverpool (N.S. Wales) " in the nest of 

 the small black ant." It appears to be the commonest species 

 of the genus, and occurs in Tasmania as well as N.S. Wales and 

 Victoria, and in the nests of several species of ants, including 

 C olohopsis gasseri, Iridoinyrmex nitidus and /, gracilis. 



Articerus hipartitus, Raffr. 



In nests of two species of ants, Crematog aster, sp., and Colo- 

 bopsis], sp. Also in nests of a species of white ant. 



Articerus dilaticornis, Westw. 



Mr. Goudie has sent a male from a nest of Iridoinyrmex 

 nitidus that probably belongs to this species. It agrees well 

 with the description; but differs from the figure in having the 

 eyes less prominent, prothoriix rather wider across apex, and 

 abdominal fovea not rounded behind but subtriangular — much 

 as in master si. 



Articerus gihhvJus, Sharp. 



Occurs in nests of Crematog aster laeviceps and of Irido- 

 myrmex nitidus. 



Articerus fortnumi, Hope. 

 hostocki, Pasc. 

 odewahni, Pasc. 



Appears to be a common species in nests of Crematogaster 

 laeviceps in S. Australia. The synonymy is according to Dr. 

 Schaufuss.
