viewed before any satisfactory result can be arrived at. We bave in tb e 

 extra-tropical part of tbis province several species of Physa, some Lym- 

 nwa, an Ancylus, Planorhes, Melanice, Paludints, and several so-called 

 Bithynias and Paludestrinas, a Pomatiopsis, TJnios, and a Cyrena. 

 Some Soutb Australian Physce are described in Reeve's Monograph of 

 tbe genus. The Cyrena of tbe Lower River Murray is named G. Angasi 

 by Prime, Journ. de Conch., vol. xii, 1864 ; and Mr. Angas in Proc. 

 Zool. Soc, 1877, describes a new Paludinella from Lake Eyre. 



Class Insecta. — Entomology has long been a favourite pursuit 

 among Englishmen, Frenchmen, and Germans, and with so many 

 workers and with an almost unbounded field of research, it is not sur- 

 prising to learn that tbe literature of this class of animals is most volu- 

 minous. Of late years specialists have arisen, and the modern biblio- 

 graphy of any order of insects is more compact and accessible. The 

 descriptions of Australian insects are scattered through so many publica- 

 tions that their long array is enough to dishearten the tyro at the very 

 commencement ; but there are a few works which deal largely with 

 Australian entomology, these are : — Donovan's " South Sea Insects," 

 1805 ; " Boisduval — Entomology of the Voyage of the French Sur- 

 veying ship the Astrolabe ;" Giierin — " Zoology of tbe Voyage of the 

 Coquille ;" and Germar — " Linnean Entomology " (1848); Angas — "South 

 Australia Illustrated," 1847, figures on plate 48, twelve species of ortho- 

 ptera, neuroptera and hemiptera, on plate 51 thirty-one species of coleo- 

 ptera, and plate 37 is devoted to lepidoptera. 



Moreover Mr. G. Masters has afforded great aid to the student in 

 the orders Lepidoptera and Coleoptera by the publication of catalogues 

 of the names of all the described species known to inhabit Australia, ac- 

 companied with a reference to the description oi each. 



Ordeb Lepidoptera. —His " Catalogue of the Described Diurnal 

 Lepidoptera," 1873, contains the names of 202 butterflies, and of these it 

 would seem that only seven are recorded as inhabiting tbis province. Mr. 

 G. F. Angas in his " S. Australia 111.," figures on plates 37 seven species 

 of Diurnal Lepidoptera, two of them are unnamed, one of which has 

 probably been described by Felder , and as three of tbe species are not 

 recorded for South Australia by Mr. Masters, tbe total number of 

 butterflies known to occur with us is ten. Mr. Angas has represented on 

 tbe same plate sixteen species of moths. Mr. Wallace (" Distribution of 

 Animals," vol. 1, p. 404), states that in South Australia there are less 

 than thirty-five species ; but does not give the names of the species.
