very nearly to the apex, where it ends in a pomt on the 
suture ; the 3rd interstice has three large punctures ; the 
shoulders are rounded, but prominent and produced for- 
ward (the marginal fold being strongly incurved), and the 
apex is strongly sinuate. The underside of the head is 
black, the rest of the under-surface and legs testaceous 
tawny-yellow.

Very closely allied to the common Chinese A. scintillans 
(Bohem.), from which no difference is perceptible, except 
the abdomen being pitchy-black (like the rest of the under- 
surface) instead of testaceous. The antennro are rather 
darker pitchy-red, and the surface of the thorax smoother, 
with narrower and much less pallid explanatcd lateral 
margins. Both species are also very closely allied to the 
Siberian A. hicolor (Dcj.) which has paler, livid-broAvn 
and only slightly a^nicous elytra, and rather longer thorax. 
The colour of the elytra in A. clialconms is always mode- 
rately bright cupreous, similar to A. parumpunctatus. A. 
fallax (Moraw.) is another allied species, differing in the 
broader thorax, not much narrower at the base than the 
elytra.
