252 PHYSODERA DAVIDIS. 



distinct, sometimes quite obsolete. Recently Fairmaire 

 described a new Physodera from China , Fokien , under the 

 name of P. Davidis Fairm. As the whole description does 

 not contain a single expression, which should not apply 

 perfectly well to P. Eschscholtzi , and moreover, as the 

 diagnosis is not accompanied by a single word of compa- 

 rison, which should let us suppose that the author has 

 known the existance of Eschscholtzi, I shall allow myself 

 to regard P. Davidis Fairm., until better evidence of its 

 specific distinctness will be given , as a mere synonym of 

 P. Eschscholtzi Parry. 



I shall now proceed to describe in this paper three more 

 species of Physodera ; two of them , originating respecti- 

 vely from Hongkong and Celebes , are closely allied to P. 

 Eschscholtzi; whether they must be regarded as distinct 

 species or as local forms of Eschscholtzi, is a matter of 

 opinion, but looking both very different and deserving 

 certainly a name, I do not see much harm in treating 

 them presently as distinct. The third species , which has 

 been already for a long time in the collection of the Ley- 

 den Museum, is labelled »Java" and is as different from 

 the two old species , as these are mutually.
