bent at the tip only, dentated below the middle, the one more so 

 than the other. The maxillse are thin and slender, gently bent 

 outwards at the base, and inwards at the apex, the outer lobe 

 corresponding with the inner one in shape and strength. The 

 palpi are robust ; both the maxillary and labial ones have joint 4 

 elongated, thin and acuminated, in fact, needle-shaped, firmly 

 implanted in the preceding one, not loosely hinged to it. The 

 maxillary ones have joints 3 and 2 robust, the former swollen 

 on the inner, the latter on the outer side. In the labial ones, 

 joint 3 is still plumper than in the others, but differs in shape 

 by being incrassated on the outer instead of the inner side, the 

 second joint being at the same time quite small and cylindric. 

 The mentum is large and simple, as above described. The ligula 

 is small, oblong, very slightly narrowed and transversely cut 

 away at the apex ; the paraglossse 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 longitudinal furrow, and 

 that both are furnished with a narrow margin at the sides. The 

 scutellum is very small, and the abdomen furnished 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 foot-brushes 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 

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

 to its wings. I have found it occasionally in considerable num- 

 bers upon the sandy banks of the Maha Oya in the neighbour- 

 hood of Negombo, close to the edge of the water.
