Emphytus is placed between Dolerus and Croesus {pi. 17.); 

 from the former it is at once distinguished by the great length 

 of the first submarginal cell, and from the latter and the Ne- 

 mati also, by its having 2 marginal and only 3, instead of 4 

 submarginal cells. 



The following are recorded as British species.

 Mr. Dale has a species of this genus with seven legs, and I 



have a fly {Chrysogaster) with the same number : in the second 

 volume of Germar's Magazine there is a figure of Elater 

 vana6z7/s of similar structure; but the most remarkable perhaps 

 is the Chrysomela hcemoptera,Jig. 5^; pi. 111. of British Ento- 

 mology. 



The Plant is Sparganium simplex (Less Bur-reed).
