as unknown to him. The whole of its appendages are damaged, 

 but the parts that are left are of the same shade of red as the 

 abdomen. 



Adelotopus fasciatus, Cast. 



Fairly common in nests of a small blackish-brown ant that 

 occurs under bark of several species of Eucalyptus and Banksia 

 about Sydney. 



Philophlaeus, sp. 



A single specimen of this genus was taken from under an old 

 log in a nest of C olohopsis c/a-sseri, and its presence there some 

 distance from the nearest living tree could hardly have been 

 accidental. It is closely allied to quadripeunis, obtusus and 

 truncatus, but with the hind angles of the prothorax more

 genus are often very variable, and I have seen but the one speci-

Thenarotes discnidaUs, Blackb.

Mr. Davey sent a single specimen as having been taken from 

 an ants' nest at Portland (Victoria), and wrote : " This is the 

 same beetle that I have seen tive or six of in one nest in a rotten 

 log on the Gellibrand River, but I was not too keen on them at

 doubt, I think, that it associates with ants." 



Staphylinidae. 



Fahu/ria faureli, Sol. 



A single specimen of this species was taken on Mount Wel- 

 lington, Tasmania, right in the centre of a large nest of CoJo- 

 bopsis gasseri. It moved freely amongst the ants, who did not
