and simple as above described. The ligula is small, oblong, very 

 slightly narrowed and transversely cut away at the apex, the pa- 

 raglossas separate from its sides a little below the anterior corners ; 

 they are setiform and reach much beyond it. The whole organ is 

 of membranaceous texture having, however, a more substantial 

 centre or back. The thorax and elytra are simple and sufficiently 

 described above. I may add that the former is divided by a longi- 

 tudinal furrow and that both are furnished with a narrow margin at 

 the sides. The scutellum is very small and the abdomen furnish- 

 ed with a short peduncle. The legs are weak, simple and nearly 

 equal, the anterior tibiae are deeply notched, the lower margin of 

 the fourth tarsal joint of the same pair is furnished with a long thin 

 spine, the apex of which fits in between the claws. I have been 

 unable to discover any footbrushes or other sexual distinctions in 

 the specimens before me, but it is not improbable that the tarsal 

 spine just mentioned occurs only in one sex. 



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

 ciety it lives upon the banks of rivers, taking like them readily 

 to its wings. I have found it occasionally in considerable numbers 

 upon the sandy banks of the Maha Oya in the neighbourhood of 

 Negombo close to the edge of the water.
