Ptinidae

 Communicated November 24th 1915 by Chr. Aurivillius and Y. Sjöstedt. 



The Australian Ptinidce seem to be but little known, not 

 more than 26 species having been deseribed up to date. Of these 

 not less than 10 belong to the genus Ptinvs L. The other 

 16 species, which seem to be more or less myrmecophilous 

 in their habits, belong to the endemic genera Enasiba Olliff, 

 Diphobia Olliff, Diplocotes Westw., Polyplocotes Westw., 

 Paussoptinus Le a and Hexaplocotes Le a (the 1 ätter from 

 Tasmania). 



The material I have collected contains 22 specimens. They 

 represent 5 different genera and 7 different species, one genus 

 and five species being new. 



It is regrettable that so many of the AustraHan insects 

 have been so badly deseribed. Many European entomologists 

 have already complained of this. To take only one instance, 

 I might mention that Ptinus alhomaculatus M'Leay was 

 originally deseribed in six lines (Träns. Ent. Soc. N. S.
