Based on characters of gross morphology, a taxonomic revision is presented of the Australian taxa of Eragrostis Wolf, comprising 69 endemic and exotic species distributed in six groups. Seventeen species are proposed as new. Ten taxa are hereby reduced to synonymy. Lectotypes are designated for 11 species. New distribution records include E. atrovirens for Australia, E. schultzii for Western Australia, E. leptocarpa and E. pergracilis for Victoria, E. minor for New South Wales, and E. sterilis for New South Wales and the Northern Territory. Polymorphy and interspecific gradation are inherent problems in the taxonomy of the genus. Also, apparent evolutionary characters such as mode of spikelet disarticulation can be inconsistent and difficult to interpret. Features of the caryopsis relating to 3-dimensional shapes, compression, surface markings, and an adnate or free pericarp are among the most useful characters for identification purposes. Cleistogamy occurs in many species, but is not reflected in spikelet morphology. Eragrostis curvula is recorded as an apomict.

Taxonomic revision of the genus Bubastes Laporte & Gory, 1836. Thirteen new species are described: Bubastes barkeri sp. nov. (New South Wales, Queensland, Victoria), B. deserta sp. nov. (South Australia), B. dichroa sp. nov. (Western Australia), B. flavocaerulea sp. nov. (New South Wales, Queensland), B. hasenpuschi sp. nov. (Queensland), B. iridiventris sp. nov. (Western Australia), B. iris sp. nov. (Western Australia), B. macmillani sp. nov. (Western Australia), B. magnifica sp. nov. (Queensland, New South Wales), B. michaelpowelli sp. nov. (Western Australia), B. pilbarensis sp. nov. (Western Australia), B. remota sp. nov. (Northern Territory) and B. viridiaurea sp. nov. (Western Australia). The following seventeen new synonyms are proposed: Bubastes thomsoni Obenberger, 1928, syn. nov. = B. australasiae Obenberger, 1922, B. olivina Obenberger, 1920, syn. nov. = Neraldus bostrychoides Théry 1910, B. boisduvali Obenberger, 1941, syn. nov. = B. erbeni Obenberger, 1941, B. borealis Obenberger, 1941, syn. nov. = B. globicollis Thomson, 1879, B. laticollis Blackburn, 1888, syn. nov. = B. globicollis Thomson, 1879, B. simillima Obenberger, 1922, syn. nov. = B. globicollis Thomson, 1879, B. obscura Obenberger, 1922, syn. nov. = B. inconsistans Thomson, 1879, B. septentrionalis Obenberger, 1941, syn. nov. = B. inconsistans Thomson, 1879, B. viridicupraea Obenberger, 1922, syn. nov. = B. inconsistans Thomson, 1879, B. blackburni Obenberger, 1941, syn. nov. = B. kirbyi Obenberger, 1928, B. chapmani Obenberger, 1941, syn. nov. = B. kirbyi Obenberger, 1928, B. aenea Obenberger, 1922, syn. nov. = B. niveiventris Obenberger, 1922, B. saundersi Obenberger, 1928, syn. nov. = B. odewahni Obenberger, 1928, B. occidentalis Blackburn, 1891, syn. nov. = B. sphaenoida Laporte & Gory, 1836, B. persplendens Obenberger, 1920, syn. nov. = B. sphaenoida Laporte & Gory, 1836, B. splendens Blackburn, 1891, syn. nov. = B. sphaenoida Laporte & Gory, 1836 and B. strandi Obenberger, 1920, syn. nov. = B. suturalis Carter, 1915. Neotype is designated and redescribed for Bubastes cylindrica W. J. Macleay, 1888 and lectotypes are designated for Bubastes thomsoni Obenberger, 1928 and B. leai Carter, 1924. Morphological characters of the genus are presented and all species are illustrated (incl. historical types) and a key is provided for all species of the genus.

The little-known Australian genus, Ahamitermes, contains four described species: A. nidicola Mjoberg (Queensland), A. hillii Nicholls (south-western Australia), A. inclusus Gay (restricted to a small sub-coastal area in mid- Western Australia), and A. pumilus (Hill) (New South Wales and Western Australia). Many new distribution records of A. hillii and some of A. inclusus are given. New observations on the biology of Ahamitermes show that the various species have a species-specific parasitic nesting relationship with either one of two species of the genus Coptotermes. They live in specific parts of the inner sections of Coptotermes nests, utilizing as food the carton composing these sections, and are thus dependent on the host for food and shelter. They are not found in any other situation. The nests of host and parasite are separated and the two species are mutually hostile. A. pumilus differs from its congeners in that it is also dependent on the host for the release of its alates which are tolerated inquilines in the host's nest. Termite associations in general and that of Ahamitermes and Coptotermes in particular are discussed.

A new genus, Wundacaenis, is erected for three new species of Australian caenid mayflies. The genus is diagnosed by possession of distinctive lobes on the anterolateral margins of the mesonotum. The distribution of Wundacaenis extends from the Kimberleys in Western Australia, through the Alligator Rivers Region in the Northern Territory, and down the eastern coast to the Shoalhaven River in New South Wales.
