I see no difference between Japanese and European 
specimens of this well-known insect.

Closely resembling the common European A. binotatiis ; 
but distinct in the punctulate interstices of the elytra and 
the broader and more regularly rounded thorax.

Differs from A. punctatipennis chiefly by the tridentate 
apical spur of the anterior tibite.

Differs from both D. pubescens and ustulatus in the 
form of the thorax, which is narrowed behind gradually 
and without sinuation, the hind angles being obtuse, and 
with only a very minute point at their apices. The sur- 
face of the head and thorax is more finely and densely 
punctured than in D. pubescens, but the punctures stand 
at considerable distances fi-om each other, especially on 
the disks ; they are shining, pitchy-black, with the limb of 
the thorax indeterminately rufous. The mouth and palpi 
are more or less pallid, the last joint of the maxillaries 
at the base and the penultimate being often black ; the 
palpi are more acutely pointed than in the allied species. 
The stride of the elytra are fine, but sharj^ly cut ; the scu- 
teUar stride wanting, the interstices very finely punctured ; 
the colour of the elytra is rusty-red, with the whole disk 
of each blackish, leaving ill-defined, narrow, apical and
