Elytra more oblong than in the other species, shining violaceous blue, with the punctures stronger than those of the thorax, and rather confusedly placed, only towards the apex more distinctly geminate-punctate-striate ; the intervals not raised, only an obtuse tubercle visible near the extreme apex; the suture on each side accompanied by an impressed line, commencing about the middle of the elytra, to the apex.
