collectors have to be thanked, in particular the National 

 Museum, Melbourne, and Mr. C. French. 



I do not purpose giving here, however, a complete generic 

 revision of our species, but where some are obviously out of 

 place to refer them to genera in which they would seem to be 

 more at home. The list, therefore, simply gives particulars 

 of the species that have been described or recorded from Aus- 

 tralia, with an attempt at a better grouping than that by 

 Kraatz, many of his genera of necessity being retained. 

 References to species described or commented upon since the 

 date of Masters' Catalogue are given ; but where noted in that 

 •catalogue, and not since referred to, the numbers there given 

 are regarded as sufficient, and are noted in brackets. 

 Where the species are unknown to me they have been left 

 in the genera in which they appear in Masters' Catalogue, 

 unless specially commented upon. 



In his "Australian Insects," pp. 160-162, Froggatt gives 

 some notes on various members of the subfamily, but the 

 species he refers to as Trichaulax marginipennis is evidently 

 T. trichopyga. On pi. xvii. four species are figured. He 

 also has given life histories of several species, references to 

 these being noted in the list. 



Figures of the markings of many species are herewith 

 given, mostly from South Australian collections, but often 

 from specimens in the National Museum or in Mr. French's 

 •collection. 



In Kraatz' s revision considerable attention was nearly 

 always given to the pronotum; but, as a matter of fact, if 

 Lomaptera (with its subgenera), Glycyphana, and Micro- 

 valgus are excluded, the sides and base are so similar in all 

 the genera that they cannot be usefully employed. The sides 

 are incurved near the apex, and again near the base, more 

 noticeably on some forms than on others, but the differences 

 are only of degree. Similarly with the base, the median 

 sinus is sometimes deeper on some species than on others, and 

 its proportion to the lateral ones varies; but the differences 

 are only of degree. The scutellum also can seldom be use- 

 fully employed. 



The dentition of the tibiae is nearly always sexually vari- 

 able, the female as a rule having more teeth than the male, 

 this being especially the case with the front pair. To adopt 

 many of Kraatz's diagnoses would often mean referring the 

 sexes or varieties of one species to two different genera. 



On the majority of species the pygidium is marked with 

 concentric scratches or strigae, usually leading up to a small 

 median space. But on some specimens the scratches, whilst 

 of the usual type, leave two small spaces, which then appear
