It is fufpected that the Dyriscus Sulcatus is only the female of the 
Dytiscus Cinereus, and by no means a diftin® fpecies, although 
Linnzus confidered it as fuch. 
Tt is common in the month of May, and thence is 5 found throughout 
the Summer. It pafles- ‘through the different changes, and exiftsin — 
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 fwiftnefs in fearch of its prey by the affiftance of its 
hinder legs, which are well contrived for that purpofe.
