50 Descriptions of New 



thin spine, the apex of which fits in between the claws, as 

 in Lymnaeum Steph. I have been unable to discover any 

 footbrushes or other sexual distinctions in the specimens be- 

 fore me and therefore conclude that accidentally they are 

 all females. 



The habits of the insect are those of the Bembidia in whose 

 society it lives upon the banks of rivers, taking like them 

 readily to its wings. I have found it occasionally in consi- 

 derable numbers upon the sandy banks of the Maha Oya in 

 the neighbourhood of Negombo close to the edge of the water.
