Dyschirius Yezoensis. 



D. polito simillimus, sed differt thorace magis ovato 

 postice et antice fere aequaliter angustato. Supra seneo- 

 nitidus, scapo rufo, pedibus rufo-piceis, femoribus anticis 

 submetallicis ; elytris minus cylindricis, elongato-sub- 

 ovatis, profundius quam in D. polito (sed minus pro- 

 fundis quam in D. impunctipenni) , striatis, striis (versus 

 apicem exceptis) crenato-punctatis, lateraliter et ante 

 apicem interdum evanescentibus sed juxta apicem lma 

 et 2nda 7ma et 8va semper profunde insculptis. Long.

Yezo ; Hakodate and Sapporo. 



Belongs to the same group as the European D. politus, 

 and offers no perceptible difference in the form of head, 

 anterior tibiae, &c. But the thorax, especially when 

 viewed from the front, is seen to be distinctly more ovate 

 and less trapezoidal, the greatest width being nearly in 

 the middle. The elytra also are conspicuously less cylin- 

 drical, being rounded on the sides, more strongly so a little 

 behind the shoulders. In its normal state the colour is 

 bright brassy, but individuals occur of a dull purpura- 

 scent pitchy hue, sometimes reddish at the tips of the 

 elytra. 



The species is similar to D. ciieloscelis from South
