I think it very jjossible that arenosus, iniquus, and impediens 

 are forms of one species ; but this can only be decided by the 

 investigations of future observers. Mr. Bates paid but little at- 

 tention to tlie Neuroptera. In other orders he proved incontest- 

 ably that, in the regions he explored, different localities pre- 

 sented local forms that to all intents and purposes are entitled 

 to be considered distinct : this may also obtain in the AscalaphidoB. 

 li. iniquus and impediens certainly appear to have the wings 

 much more glossy than arenosus ; and iniquus especially has nar- 

 rower anterior and more dilated posterior wings. 



The prothoracic lobe of the male in arenosus is much less evi- 

 dent than in that of tho group of costatus : it is smaller, and so 

 closely applied over the front portion of the mesonotum as 

 to be scarcely distinguishable from the anterior lobe of that 

 segment.
