Distinguished from Colpodes by the tarsal claws having 
a long tooth or spine at their base. I can find no differ- 
ence between Japanese specimens and others from Northern 
India (from the late Judge Benson's collection) with which 
I have compared them. INIotschulsky's description suits 
as far as it goes, but he overlooked the structure of the 
claws and placed it in the wrong genus.

Hiogo ; Nagasaki ; Yesso (Moraw.) Also China. 
Very much resembles Colpodes atricomes, but the 4th 
tarsal joint is triangular and barely emarginated even in the 
anterior feet, showing that it does not belong to the same 
genus. The form of the head and thorax is very different 
and approximates that of A. (^Limodromus) angusticollis, 
from which it is distinguished by its much broader and 
shorter thorax, with obtuse and strongly reflexed hind 
angles, and by the much greater width and relative size of 
the elytra. 
The species belonging to Eschscholtz's and Motschidsky's 
genus Limodromus differ from the Anchomcni not only in 
fiicies, but in the short and broad ligula scarcely visible 
above the root of the labial palpi ; the same organ being- 
narrow and porrect in Anchomenus. Plntynns seems to 
me also a very good group, and I cannot but think it was 
a retrograde step in the science, to fuse these all into one 
genus with the name first of Anclwmenus (held for some 
years) and then oi Platynus.
