" I have no special recollection of the nest of longiceps, but I feel 

 sure that the log when raised only disclosed a series o£ tunnels from 

 which the ants were taken. The openings to the nests of jwidtoni in 

 the Zoological Gardens were very characteristic. They were scattered 

 sparingly over the bare turf and were all alike, being deep, circular, little 

 craters, from memoiy about 1^ inches in diameter, with a small central 

 hole passing vertically downward. The crater was surrounded by a wall 

 of pure yellow sand evidently brought \ip from below the superficial 

 soil, from which it was entirely free. Th.e 3'ellow sand also lined the 

 crater, which, with its wall, was a very conspicuous object. Very few 

 ants were seen in the craters, never more than one or, at the most, two in 

 each.''— E. B. P. 



A. pouUoni is described in a paper now being printed for the 

 Ann. and Mag. Nat. Hist. 



Plieidole variabilis Mayr var. — A single 1/ under stone. Blue Mts., 

 N.S.W., near Mt. Victoria, 23.viii.14'. This appears to be one of the 

 numerous varieties of this species. It is very like var. ri/f/occijjuf For. 

 from Queensland, as it has the whole head longitudinally striate and 

 reticulate between the striae, but the scapes are somewhat shorter than 

 in rngoccipuf. 



Monomovium {Mitara) ilia For. — ^ ^ and 4 $ 5 , from nests in 

 rotten wood, S. Perth, Zoological Gardens, and Swan Eiver Bank, 

 2.viii.l4 (i. h Seouef; H. M. Giles; E. B. P.). 



Crematogaster austraJis Maj'r. — ^ ^ , many c? d" , 3 alate and one 

 dealate 5 » S. Perth, Swan Biver bank, near Zoological Gardens. From 

 3 nests in rotten Melaleuca trunk, 2.viii.l4 (Z. le Seouef; E. B. P.). 

 " The nests, of which two were found on one tree, were excessively 

 populous." — E. B. P. 



This I take to be Mayr's species from his description, though I have 

 iiever seen a co-type or a specimen named by a myrmecologist who has 

 seen the type, and I am not completely satisfied that this is austral is. 



C. rufotestacea Mayr. — 5 ^ ^ , under log or stone in bush, near 

 Perth, Yallingup to Mammoth and Lake Caves, 3l.vii.l4. 



This is a very abundant species in Western Australia. 



Sulvfamily IV. Dolichodebixae Forel. 



Iridomyrmex detectus Sm. — ^ ^ . Mundaring Weir, near Perth, 

 3.viii.l4 ; Perth, stations on railway to Busselton, 30.vii.l4; Adelaide, 

 Outer Harbour, 27.viii.14. " The entrance to the nests was very charac- 

 teristic, being a single opening, leading vertically downwards, in the
