It is fufpec^ed that the Dytiscus Sulcatus is only the female of the 

 Dytiscus Cinerens, and by no means a diftinil fpecies, although 

 Linnasus confidered it as fuch. 



It is common in the month of May, and thence is found throughout 

 the Summer. It paiTes 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 Infe6l, or tender vegetables. It darts 

 with aftoniftiing fwiftnefs in fearch of its prey by the affiflance of its 

 hinder legs, which are well contrived for that purpofe.
