Victus Bembidiorum. 



Apparently closely allied to Trechus, and an aberrant form of 

 the same tribe to which the latter genus belongs. The mentum 

 and palpi appear to agree entirely ; the insects differ, however, 

 in the structure of the ligula (which, in Spathinus, is entirely 

 that of a Bembidium) and the sculpture and vesture of the an- 

 terior male tarsi. In spite of the latter anomalies, the pre- 

 eminently characteristic shape of the palpi convinces me that 

 the insect must find a place where I have put it. It is also 

 closely allied to my genus Ochthephilus, differing from it, how- 

 ever, in the ligula, palpi and labrum. The generic name Spa- 

 thinus signifies a staggard, and I have chosen it with regard to 

 the shape of the terminal joint of the palpi. The insects are 

 common throughout the south-west and west of the island, 

 where they live in the manner of the Bembidia, under decaying 

 vegetable matter, upon the banks of lakes and rivers, &c.
