I sent a sketch of an insect of this genus to M. Latreille, and 
he was of opinion that it belonged to a genus he had constructed, 
but which is not yet published, under the name of Orthorhynchus. 
1 have since been informed by him, that the type of that genus is 
Lixus semipunctatus Fabr., which from Olivier's figure appears to 
be more nearly related to Lirus bidentatus of Mr. Donovan, and 
is distinguished by acuminated elytra | and filiform antennx ; 
whereas no species of Eurhinus, and there are several, has acumi- 
nated elytra, and the antennz terminate in an oblong clava, the 
last joint of which, in the males, is very long. Olivier describes 
Livus semipunctatus as antennis moniliformibus vix extrorsum cras- 
sioribus (v. 242. n. 249. t. xii. f. 141.) In L: bidentatus the an- 
tennæ are not moniliformes, but they are extrorsum vix crassiores. 
So that Orthorhynchus seems to be a connecting link between 
Eurhynus, the antennz of which are submoniliform at the base, 
and Lirus bidentatus, but belonging to the same genus with the 
latter. There are-several species of Orthorhynchus in Mr. Mac- 
Leay’s rich cabinet. As Lixus semipunctatus is in the Banksian 
cabinet, it may be easily ascertained whether these observations 
are correct or not.
