rus ; Elophorus may properly be divided into two 

 sub -genera : tbose with striate elytra, and those 

 which have the wings deeply sulcated or porcate. 

 Nubilus is often found at the roots and stalks of 

 cabbages ; the water held in the leaves of the plants 

 being quite sufficient to saturate the ground around 

 and satisfy the insects. I have watched the same 

 insects for eight or nine weeks at the same plant, 

 and never knew their numbers during that time in- 

 creased or diminished. It should be remarked that 

 no water was within a hundred yards, and the nearest 

 was a well many feet beneath the surface of the earth. 

 To this genus belong also El. fennicus Gyll. and pro- 

 bably sulcatus of Dahl and Costatus of Schonherr. 



Sp. 4. Mumeralis. — This insect is not mentioned 

 by any modern writers. I give it as an Helophorus, 

 with a doubt. 



Sp. 5. Flavipes. — This insect is the same as the 

 Bup. granulans Linn. The Fabrician name of 

 flavipes must therefore be abandoned. 



Sp. 6. Crenatus. — Mr. Stephens gives this insect 

 as an Hydrochus. Mr. Erichson, however, having 

 examined the Fabrician Cabinet, declares it to be 

 Latridius porcatus.
