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 Arbaces; 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 Zcones 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 Eucheiride, which I consider as a family 
closely allied to the Dynastide, and forming a sort of connecting link with 
the Goliathide. Professor Klug and Dr. Burmeister consider longimanus, Fab. 
as belonging to the Trichiide. 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.
