 elongate, a little angular laterally at middle, either transverse at tip 

 or slightly emarginate, gense sinuate at middle, the head is trans- 

 versely plicate, and scrobiculate behind the cephalic carina in the 

 male, but not in the female ; prothorax closely scrobiculate ; elytra 

 narrowly punctulato-striate, strias non-geminate, intervals plane, 

 almost impunctate in the male, and very slightly and sparsely 

 aciculate in the female ; pygidium closely punctulate, the punc- 

 tures not well defined ; matasternum with a broad, deep, basal 

 impression. 



Male : Head with a median, much raised transverse laminate 

 carina truncate and sharply dentate on each side, and having in the 

 centre a . tooth longer and sharper than the lateral ones ; anterior 

 part of the prothorax vertical, deeply excavate laterally above the 

 outer angles which are not acuminate, and having the apical anterior 

 part ridged with a sharp, slightly projecting carina straight for the 

 greater part of the width, then briefly sinuate, sharp at both ends 

 and suddenly deflexed obliquely above the anterior impressions and
