This is another species which does not seem to fall into any of 

 the named groups known to me of Bembidium, or to have any- 

 very near ally ; it might perhaps with some reason be treated as 

 the type of a new genus. In general appeai^ance it is extremely 

 like the European Trechus secalis, Sturm, in miniature ; but with 

 the palpi of a Bembidium, — the apical joint nevertheless nearly 

 as long as the penultimate though very slender and cylindric. 

 Compared with T. seccdis, the head scarcely differs except in the 

 eyes being decidedly more prominent and the neck much more 

 defined, the antennae are exceedingly similar but perhaps a trifle 

 longer in proportion, and the prothorax scarcely differs except in 

 the basal lobe being stronger ; the elytra are longer and more 

 parallel-sided and of quite different sculpture. I observe that all 

 the setse on the upper surface are extremely long and slender. In 

 the two examples before me (both males I think) the basal two 

 joints of the anterior tarsi are only moderately dilated. The 

 apical ventral segment is strongly transverse, and slightly 

 emarginate at the apex ; it does not bear any setiferous punc- 

 tures, but its whole surface is sparsely studded with line scratch- 

 like punctures. The elytra not abbreviated and truncated at the 

 apex will inter alia distinguish this insect from the South American 

 Thalassobius which in some respects it approaches. The foveated 

 elytra recall to mind B. bipunctatwn, Linn., but in the present 

 species the front fovea is nearer the base, and there is an additional 

 one near the apex. It is to be noted that the basal lobe of the 

 prothorax gives that segment the appearance of being narrowed 

 behind, but it is not narrower across the hind angles than across 

 the front.

N.B. — Besides the above-named new species of Bembidiides I 

 have Bembidium ocellatitm, Blackb., and Tacliys similis, Blackb., 

 and Flindersi, Blackb., all from the Victorian Alps.
