REMARKS ON AUSTRALIAN PTINID^ AND 

 DESCRIPTIONS OF NEW GENERA AND SPECIES. 



By a. Sidney Olliff, F.E.S. 



Assistant Zoologist, Australian Museum. 



In this Paper I have drawn up descriptions of some new- 

 Australian species of Ptinidte belonging to the subfamily in 

 which the antennte are inserted upon the front of the head. I 

 have not attempted to make use of the tabular characters 

 proposed by M. Boieldieu in his " Monographie des Ptiniores," as 

 I find the Australian species of Ptinus do not permit of sub- 

 division on colour and marking alone. 



Ptinus exulans, Erich., is known to me from Jerrawa, Bowenfels, 

 Sydney and Tasmania. It varies slightly in the size and shape of 

 the white spots. 



Ptinus fur, Linn. — I have seen specimens of this ubiquitous 

 species from Melbourne and Tasmania. 



Mezium affine, Boield. and Gihhiuin scotins, Fabr. have both 

 been taken in the neighbourhood of Sydney, the former in some 

 numbers, but they are undouTjtedly introduced species. 



Ectrej^hes formicarum, Pasc. — This species is known to range 

 from Adelaide to West Australia. I have seen specimens from 

 Gawler, Adelaide and Nichol Bay and it has been recorded from 

 Freemantle. 



All the following species, with the exception of Ptinus adeps 

 and P. imulus which were kindly placed at my disposal by Mr. 

 Masters, are in the collection of the Australian Museum.
