 punctate, the apical area foveately impressed ; sternal process 

 strongly anteriorly produced, compressed above and anteriorly

 ochraceous ; head as long as anterior tibiae, the lateral margins 

 robustly reflexed, apical margin sinuately truncate ; pronotum with 

 the lateral angles anteriorly and less outwardly produced, their 

 apices level with the apical latitude of the head, their anterior 

 margins coarsely shortly serrate for about half their length from 

 base, their apices subangularly rounded, their upper surface sparsely 

 coarsely punctate, disk of pronotum sparingly punctate, more thickly 

 punctate before the anterior margin and much less punctate on 

 basal marginal area, a darker opaque transverse narrow fascia 

 between the anterior bases of the pronotal angles and more narrowly 

 continued along the inner margins of the produced angles, posterior 

 margin convexly produced over base of scutellum ; scutellum very 

 sparingly punctate, its apex moderately longitudinally sulcately 

 impressed ; corium very thickly finely punctate ; rostrum slightly
