Hoplomyrmus micans Gerstäcker

8. Hoplomyrmus micans Mayr. Storm Creek, four speci-

mens. This has no connection with Mayr's species, but is identical with that subsequently described by Wheeler as Polyrhachis (Campomyrma) macropus (Trans. Roy. Soc. S. Aust., xxxix, p. 821,. 1915). It is widely distributed throughout Central Australia.

' 9. Hypoclinea flavipes Kirby. Tempe Downs. Ants from Porcupine grass (Triodia pungens). This very distinct species is an Iridomyrmex, and identical with;that subsequently described by Forel as Iridomyrmex rostrinotus (Rev. Suisse Zool., xviii, p. 53, 1910, [worker, queen, male). The descriptions of all three forms by Forel are very complete, and it is unfortunate that his name must give way to Iridomyrmex flavipes Kirby. It is known as the Spinifex Ant, being so named from its habit of collecting the gum from the leaves of this grass to construct its nest. It is widely distributed, being found wherever the spiniiex grows.
