Hab. Norra America, Canada ?, Illinois *, Georgia! 7, Louisiana ?.—Panama, Volcan 
de Chiriqui (Champion). 
Differs from A. hornt in its narrower and more ovate form, smaller size, broader 
head, longer thorax, more robust antenne, piceous colour, and more glabrous surface. 
This species, which appears to be abundant in Chiriqui, may be known by its 
exceedingly convex form, smooth, very shining, and apparently impunctate surface, 
slender legs and antenne, slightly ovate elytra, and piceous colour.

caput atque pronotum sat longioribus atque latioribus, prope media latissimis, indistinctissime punctulatis, 
lateribus valde rotundatis, levissime marginatis ; pedibus sat brevibus, rufo-testaceis, tarso unico relicto
