The folldwing new genera of Caiabidae have been proposed: 



Amerinus for Bradycellux luiuiris Lee. In the first description 

 (i, p. 7) no distinctive generic characters are given. In fact there are 

 none if we except the piesence of a few squamules on the middle male 

 tarsi. The new name is unnecessary. 



Glycerius for Bradycellus nitidus Dej. The character given being 

 the number of setse along the lateral margin of the thorax. The value 

 of this will be recognized by those having some knowledge of the Cara- 

 bida?. The name is also unnecessary. 



I — Bembidium dejectum C2i?,t\. This species belongs to that series of 

 the Peryphus group in which the dorsal punctures are at the middle 

 of the third interval, it should therefore he \A?iced \\\i\\ ephippiger 

 znd grandicolle (Lee. Proc. Acad. 1857, p. 4). 



2 — Bembidiiim vinnuliun Casey. Should be placed in the series with 

 scopulinum and picipes. It is remarkable in the large and deep 

 punctures of the stri^. 



3 — Barytachys gemellus, Casey. Closely related to incurvus and differs 

 in the absence of punctures in the basal stria of the thorax. 



4 — The difference in the measurement of the episternum of the meta- 

 sternum between Mr. Casey and myself results from the fact that I 

 compare the anterior side with the internal edge while Mr. Casey 

 measures the piece really diagonally. 



5 — This species must at present remain in Bradycellus but the middle 

 tarsi being as widely dilated as the anterior maik it as a very peculi- 

 ar species.
