This is one of those genera which, without any strong charac- 

 ters, must be constituted partly on account of their p'eculiar habit, 

 and partly because their characters collectively are not" in accord 

 with those of any other genus. It is apparently allied to Po- 

 ropterus, although the metathoric episterna are very large.

The following species of Poropterns may be taken as fairly 

 congeneric with the four described by Mr. "Waterhouse in the 

 ' Transactions of the Entomological Society ' (ser. 2, ii. pp. 196- 

 200) ; but they do not seem to range very satisfactorily in the 

 genus when we consider it has P. antiquus for its type. I have 

 yet some twenty approximate species ; and unlil they are worked
