Mentum a little attenuate laterally from the base to the tip, deeply 

 emarginate at apex, somewhat concave in the middle, and densely 

 bristly, labial palpi moderately short, joints of nearly equal length, 

 the two basal ones sub-cylindrical, the apical one sub-fusiform, lobes 

 of ligulae long, broadly divaricating, upper lobe of maxilla normal, 

 inner lobe much longer than in Ajyhodiiis but very slender ; joints of 

 maxillary palpi somewhat long, apical one fusiform and slightly 

 truncate at tip ; clava of antennae small ; head more or less deeply 

 emarginate in the anterior part of the clypeus, gense projecting ; pro- 

 thorax convex, very broadly grooved longitudinally in the centre and 

 with the outer margins depressed and marginate ; scutellum narrow, 

 sub-oblong ; elytra convex, acuminate behind, three or four costate 

 with the intervals plane, epipleura moderately broad and quite 

 distinct right to the apical part; pygidium covered by the elytra; 

 abdominal segments free ; prosternum not carinate, metasternum 

 very broad and long, quite plane, grooved longitudinally but not 

 impressed ; femora and tibiae compressed, anterior coxae very broad, 

 anterior tibiae broadly dilated internally in the shape of a curved 

 lamina truncate at tip close to the straight, lanceolate apical spur,
