This species bears much general ist a ie to that which I 
take to be A. Plutus, Chevr., but differs from it inter alia by the 
much shorter longitudinal channel of its pronotum, by the much 
less coarse sculpture of its elytra, and by the well-marked longi- 
tudinal carina that traverses the whole length of the external 
face of its tibi.

Very closely allied to A. amabilis, Blackb., but satisfactorily 
distinguishable by the absence of the subscutellar gibbosity on
