In the Cabinets of Mr. Dale and the Author. 



These insects, together with their larvae and pupce, are very 

 abundant on the borders of rivers, lakes, and ponds, as well as 

 on the sea-shore, where they inhabit the Zosfera and rejecta- 

 menta. In fine weather they are extremely active, running 

 with great speed, and jumping with astonishing agihty; but in 

 dull days they lie concealed in the cracks of the mud, under 

 stones, &c. 



The little attention that has been paid to this genus renders it 



impossible to determine the species with accuracy, but to those 



that appear to be undescribed I shall add short descriptions.
