It is fufpeted that the Dyriscus Sulcatus is only the female of the 
Dyriscus Cizereus, and by no means a diftinct {pecies, although 
Linneus confidered it as fuch. 
It is common in the month of JZay, and thence is found throughout 
the Summer. It pafles through the different changes, and exifts in 
the adult ftate in the water; and like others of the fame tribe, devours 
the fmaller kinds of aquatic Infect, or tender vegetables. It darts 
with aftonifhing {wiftnefs in fearch of its prey by the affiftance of its 
hinder legs, which are well contrived for that purpofe.
