A very small species, of delicate formation and colour- 

 ing. Antennae testaceous, moderately stout, but not 

 thickened towards the apex ; joints one and two rather 

 stout, and of moderate length ; three not much more 

 than half as long as two, much narrowed at the base ; 

 four shorter than three, subquadrate ; five a little longer 

 and stouter than four ; five to nine differing little from 

 one another in length and breadth, each one distinctly 

 narrowed towards the base, the length of each very 

 nearly as great as the breadth ; ten rather longer than 

 nine, the eleventh joint half as long again as the tenth. 

 Head subquadrate, with a distinct impression above, very 

 finely and pretty densely punctured. Thorax rather 

 wider than the head, and a little narrower than the elytra ; 

 its length about equal to its breadth, a little narrowed 

 behind, with a longitudinal channel in the middle, ex- 

 tremely finely and pretty closely punctured. Elytra 

 lighter in colour than the head and thorax, and not so 

 shining ; fully one-third longer than the thorax, densely 

 and very finely punctured, the punctuation denser than 

 on the rest of the upper surface. Abdomen with all the 

 segments on the upper side finely and tolerably closely 

 punctured, the punctuation of the terminal segments 

 being rather more sparing than that of the basal ones, 

 its apex testaceous. Legs yellow. 



In the male, the seventh abdominal segment underneath 

 is rather more produced than in the female, and its hind 

 margin is rather more rounded. 



Common on the banks of the Scotch rivers ; it is found 

 in company with Thinohius linearis, which it resembles 

 greatly in colour and appearance.
