 base emarginate in middle, lightly rounded on each side of 

 peduncle ; anterior angles roundly obtuse, a little advanced ; 

 basal angles marked, obtuse ; border reflexed, wide in front, 

 becoming narrower backwards ; median line linear, extending 

 from anterior to basal margin, placed in a wide channel in middle 

 of length ; lateral basal impressions wide, shallow, irregularly 

 shaped, distant from lateral margin, attaining the base ; the space 

 between the basal impressions depressed, striolate ; posterioi' 

 marginal puncture placed very near the edge a little before the 

 basal angle. Elytra wider than prothorax (17 x 12-75 mm.)^ 

 widest behind the middle, truncate on base, widely rounded 

 behind, depressed on disc towards base, very gently declivous 

 to apex, decidedly declivous on sides from seventh interstice ; 

 sides rather strongly rounded, narrowed to base ; apical curve 

 short, obtuse, obsoletely sinuate on each side, a light emargination 

 at suture ; striae wide, shallow, finely punctate ; stride at base of 

 first interstice short, distinct ; interstices raised, lightly costate, 

 their summits not shining, fifth and seventh stronger than others, 

 seventh strongest, eighth convex, ninth not defined from margin, 

 a row of strong punctures along its inner margin and a row of 

 very small irregularly placed punctures indicating the place of the 

 ninth stria ; lateral border strongly reflexed in middle of length, 

 much less so on apical curve and behind the shoulders, forming a 

 short upturned projection at the humeral angles ; marginal 

 channel wide, narrower towards base ; basal border arcuate on 

 posterior margin ; third interstice with three or four punctures 

 along its course, the anterior placed on basal fourth near third 

 stria, the others on apical two-thirds, the posterior distant from 

 apex. Prosternum longitudinally impressed between coxse, 

 setigero-punctate ; mesosternum and metasternum Ijevigate. 

 Ventral segments smooth, third, fourth, and fifth setigero- 

 punctate on middle of posterior margin. Legs long, light ;
