This interesting little beetle might at first si<;ht be mistaken for 

 a Lseinophlceus, of which it has the size, depressed form and colour, 

 the prominent eyes, however, and cordate thorax — to say nothing 

 of its habitat — remind one very soon of its real connexions. I 

 do not think there can be any doubt that this insect forms a new 

 and interesting addition to the Bembidiidse. In fact the question 

 whether it belongs to this tribe or not, depends, in my opinion, 

 mainly upon the inferences drawn from the structure of the ter- 

 minal joint of the palpi. It is true that this joint attains in 

 Ochthephilus a degree of development unequalled amongst the 

 Bembidiidse ; as, however, this development is not confined to 

 the one particular joint alluded to, but affects the entire organ of 

 which it forms a part, it can hardly be said to be a variation of 

 much importance ; and as, moreover, the general shape (indepen- 

 dently of the elongation) and mode of insertion are the same as 

 in the typical Bembidiidse I have not hesitated to refer my n. g. 

 to this tribe. 



The head is as broad as the thorax and altogether of about 

 the same size, it is strongly triangular from the eyes to the tip of 

 the mandibles, the forehead is impressed with 2 deep longitudinal 

 furrows, the eyes are large, rather oval and prominent, behind 

 them the head is abruptly contracted into a thick neck. The 

 antennas are long and thick reaching nearly to the middle of the
