The species of this genus are very "difficult to dea with on 
specimens,—and also from the absence (allud cor- 
daire) of any readily available character for determining the 
x of specimen tudying a considerable number of 
‘tralia I find, owing to the difficulties mentioned, a certain 
number of forms which I believe to represent additional 
— but which I hesitate to treat as certainly distinct, and

The diete of some of the Ar@oceri described below do not 
altogether agree with Lacordaire's diagnosis of the genus, but T 
am satisfied that the characters in question are not truly generic.
