The most recent issue (no. 13) contains revisions of Paregle (4 spp., of which one is new), a genus of public health interest with coprophagous larvae, Acridomyia (one species, a parasitoid of acridid grasshoppers), Adia (one species whose larvae contribute to the recycling of cow dung), Hylemya (3 species, with coprophagous lavae) and Anthomyia (23 spp., of which 14 are described as new). larvae of the last genus are saprophagous, developing mainly in bird and mammalian faeces and rotting fungi. Like preceding issues, this new issue will be of importance to the work of agricultural, as well as taxonomic entomologists and academic institutions.

This part deals with 51 species of Anthomyiidae in the genera Subhylemyia (2 spp.) Hydrophoria (5 spp., 1 new to science) and Zaphne (44 spp., 11 of them new to science). Of these 51 species, 23 also occur in the Palaearctic Region.

As in previous parts of this revision (reviewed: 120: 20: 121: 178; 123: 156; 130: xv; 133: (1), comprehensive illustrations of both male and female terrninalia are provided, accompanied by numerous distribution maps, eight photographs of parts of adult flies, keys to both males and female adults. The species are phylogenetically arranged into subgenera, sections and superspecies with their synapomorphies suggested.

Past confusion over the identity of many species in the large genus Daphne is evident in the synonymy citations given under each species. The admirable practice of listing misidentifications within quotation marks (and including the author of the species name clearly separated from the author of the reference) makes for an unambiguous history of the nomenclature of each species. As well as detailed (and very uniformly structured) descriptions of each species, there are notes on synonymy which clarify the numerous misidentifications and errors of earlier workers. Comprehensive details are also given (where known) of habitat association, collection dates and biology. Worthy of mention is the frontata superspecies group in the genus Zaphne. Previously many species were misidentified; it is now very satisfactorily revised. It contains 21 closely related species (six here described as new), mainly identified by reference to the male genitalia. Only five species of this superspecies were previously known trom the Palaearctic; this revision adds a further two species (aculeara Griffiths, sinuata (Huckett)) which are common to both Siberia and the north west Nearctic region. No doubt several more species whose range extends on either side of the Bering Straits await discovery in Siberia. Thanks to this work, identification of material from there will now not be too difficult.

The high standards of earlier parts of this revision are continued in this work; it should be in every museum and university library where insects. especially flies, are studied, not only for its specific value to specialists. but as an example of the standard required today in taxonomic revision. Once again l congratulate Dr Griffiths and the publishers on this invaluable work.
