As Motschulsky gives two joints only as red in planicollis, 

 Harold rightly rejects his name for the species, to which 

 his description in other respects applies.

Mr. Lewis has brought home a large series of this 

 species, which I find agree with East Siberian examples 

 in the structural differences which separate the species 

 from the European P. lepidus, It is a much larger and 

 more robust insect, and in all its varieties distinguishable 

 by the sides of the thorax falling obliquely on the base, 

 thus forming an obtuse angle, instead of being sinuated 

 as in P. lepidus. 



Pcecilus prolixus, Putzeys.

 Pcecilus Koyi, id. olim (nee Germar.). 



Yezo. 



Differs from P. fortipes apparently only in the sides of 

 the thorax being regularly arcuated. I have East 

 Siberian varieties of P. fortipes which answer to this 

 description, but have failed to detect any in Mr. Lewis's 

 series from Yezo.
