596 Rev. F. W. Hope on some Nondescript Insects from Assam. 



The second insect is the type of the genus Protomacrus of Newman, and 

 will be found refigured and redescribed in the fourth volume of the Entomo- 

 logical Magazine, at page 256, under the name of Arhaces ; the name, how- 

 ever, of bimucronatus, originally given by Pallas, ought to be retained ; and I 

 must add, that I suspect there is some error respecting the locality of Smyrna, 

 as Pallas in his Icones Insectorum expressly says respecting this species, that it 

 is one particularly worthy of notice, and inhabits Amboyna ; it is probable, 

 therefore, that it might have been imported into Smyrna. With regard to 

 Cheirotonus, I place it with the Eucheiridce, which I consider as a family 

 closely allied to the Dynastidce, and forming a sort of connecting link with 

 the Goliathidce. Professor Klug and Dr. Burmeister consider longimanus, Fab. 

 as belonging to the Trichiidce. I own I differ from both authors ; and as 

 the anatomical sections of the mouth are now accurately figured, I willingly 

 leave individuals to draw their own conclusions.
