margine basali sinuata, scutellum versus valde producta, angulis acutis; elytris quam caput atque pronotum 
parum latioribus, vix longioribus, ante media latissimis, indistinctissime punctatis, punctorum ordine 
humerali profundo, et ad suturam linea impressa conjuncto, stria suturali profunda et distincte punctata, 
lateribus leviter rotundatis, apicibus latis, minime rotundatis; abdomine rufo, sat obtuso, indistincte

punctures of the basal row not deep and rather remote from each other; sides moderately rounded ; basal 
margin sinuated, much produced towards the scutellum, with the angles acute, Scutellum very small, 
obtusely triangular. Elytra rather broader but scarcely longer than the head and thorax, widest before 
the middle, very indistinctly punctured; humeral row of punctures deep, and joined to the suture by an 
impressed line; sutural stria deep and distinctly punctured ; sides slightly rounded ; extremities broad,
