I am not at all satisfied with this sub-family. The 

 tables of Audouin and Brulle have been adopted, 

 with the exception of the genus Catapiesis, which 

 is apparently an Ozsena. Campylocnemis, in my 

 opinion, ought to be united with the Trigonoto- 

 midse, if it is not considered as an intermediate 

 between Morio and Catadromus. Of the habits 

 of these insects we are altogether ignorant.

True Helluo belongs to New Holland, the East 

 Indian sub-genera are allied to it ; there is a pro- 

 bability that the sexes of some of these genera, when 

 better known, will lead us to a more accurate 

 grouping than can at present be done. Helluo- 

 morpha of the New World will eventually be sub- 

 divided into several sub-genera. For an account 

 of the characters of ^Enigma, Vid. Ent. Mag. 

 fifteenth part, page 449, where the details are 

 published by Mr. Newman.
