OF PUILADELPIIIA. 89 



This appears to be a much smiillor species than the Iflppohosia 

 ftvit of Oliv., to which it is very probably allied, though on coij.- 

 parison with Oliver's description I conclude it is very sufficiently 

 distinct. It has, like that insect, slight rudiments of wings.
