XL. — On new Species of Histeridas and Notices of others, 

 tvith Descriptions of new Species of Niponius. By G. 

 Lewis, F.L.S. 



[Plate VIII.] 



I TROPOSE to call this paper the fortieth of the series, now- 

 ranging over many years, in this Magazine, notwithstanding 

 that the genus Niponius has been assigned lately to a new 

 family, Niponiidse, by the consension of entomologists gene- 

 rally. The figures of the Histeridaj given have been drawn 

 from the types in the British Museum ; those of the Niponius 

 are in my collection.
