Articepus curvicornis, Westw. 



Originally recorded from ants' nests in Melbourne. Mr. 

 Goudie has correctly mated the specimens sent to me ; the 

 female has much shorter and less curved antennae than the 

 male. The species occm's also in New South Wales, South 

 Australia and Tasmania. 



It is the only species of its genus known to me from Tas- 

 mania, where it occurs in the nests of Iridomyrmex gracilis, 

 Loun.^ 



Articerus regius, King. 



Mr. Goudie has given me a specimen which appears to be a 

 female of this species. It is, a.t any rate, the only one I have 

 seen having both the prothorax non-foveate and the antennae 

 long. King's specimens were from Liverpool (N.S. Wales) and 

 " ants' nests in wood." 



Apticepus gibbulus, Sharp. (?) 



Mr. Goudie has given me specimens of a species which has the 

 met.asternum and middle tibiae as described in the male (the 

 only sex kno\^Ta to Sharp) of this species. The antennae of the 

 Birchip specimens, however, are quite strongly curved at the 

 base (more strongly and regularly than in curvicornis), whilst 

 Sharp says of gibbulus " antennis cylindicis apicem versus in- 

 crassatis, apice truncate " ; and, again, " The antennae are mode- 

 rately long, distinctly longer than the head, slender at the base, 

 rather stout at the abruptly truncate extremity." I have not 

 ventured to describe the species as new, however, as the curva^ 

 ture of the antennae, strong as it is, is not noticeable from 

 certain directions, and many of the species of the genus are 

 very widely distributed. 



The female of the Birchip species has the metasternum and 

 middle tibiae normal, and the pygidium not impressed. 



Mr. Goudie also sent to me for examination several other 

 species of PselajDhidae that wei*e taken by him in ants' nests, 



1 I ain indebted to Mr. Froggatt for the name of the ant.
