Aphodiides. 



This group (Lacordaire's second tribe) of the sub-family Co- 

 prides is readily distinguished from the true Coprides (Lacor- 

 daire's tirst tribe) infer alia by the presence of two spines at the 

 apex of the hind tibae — the true Coprides having only one spine- 

 It is largely represented in Australia in respect of species, and 

 fairly numerously in respect of genera. Masters' Catalogue enum- 

 erates 14 species attributed to five genera; and since the publi- 

 cation of that catalogue 20 species have been added, one of them 

 appertaining to a genus not previously recorded as Australian 

 (Rhyssemus). One genus and species, however [Pedaria (Apho- 

 dius) geminatus, Macl.], has been shown to be wrongly attributed 

 to the group, and one generic name (Proctophanes, noni. praeocc.) 

 has been replaced by a new name (Proctammodes). Moreover, 

 there is a want of evidence of the occurrence in Australia of 

 one of the genera (Ammoecius) enumerated by Masters. Eight 

 species have been attributed (all by Macleay) to Ammoecius, some 

 of which are known to me somewhat certainly, and I do not find 

 a genuine member of the genus amdng them, or among the other 

 Australian Aphodiides that I have had the opportunity of examin- 

 ing. I furnish below some notes on the species that Macleay 

 described, and add descriptions of a number of new species, 

 among which will be found representatives of Psammodius and 

 Saprosites — genera that have not hitherto been recognised as 

 Australian — and also a species that I place with some hesitation 

 in Euparia (another genus not previously recorded as Australian). 



The following tabular statement shows the characters that I 

 have relied upon in apportioning the species before me to their 

 genera. As there are, among the new species described below, a 

 few that do not seem quite typical representatives of the genera 

 in which I have placed them, and which may possibly be attri- 

 butable to closely allied genera unknown to me that may have 

 been formed for Aphodiides of regions outside Australia (the 

 Aphodiid genera being for the most part widely distributed), it 

 seems well to note the fact that I have referred the species to
