This insect resembles an Athyreus in general appear- 
ance, but the well-developed abdomen and the structure 
of the antenne and the scutellum leave no room for 
doubt that it should be placed in the genus Ochodeus ; 
it is remarkable, however, for the great length of the basal 
joint of the posterior tarsus, which equals the four follow- 
ing joints taken together.

This species is extremely close to B. furctum. It differs 
in being slightly less convex and in having the elytra less 
rounded at the sides. The sides of the thorax, especially 
near the anterior angles, are in B. farctum opaque and 
minutely granulate, whereas in the Japanese species this 
part of the thorax is thickly and somewhat strongly 
punctured and not opaque. 
The head is rugulose, with a transverse carina behind ; 
the clypeus is furnished in front with a minute (almost
