 middle, wider across base(3-l mm.) than apex(2-5 mm.), depressed 

 near base, strongly declivous to anterior angles; sides lightly 

 rounded, obliquely narrowed to base, lightly sinuate just before 

 basal angles; apex emarginate; anterior angles rather prominent 

 :but obtuse; base truncate on each side, lightly emarginate in 

 middle; basal angles rectangular but obtuse at summit; border 

 wide, reflexed, extending on each side of base to basal impres-

Belongs to the group of which iV. nitidicollis Chaud., is the 

 type. Very closely allied to iV. nitidicollis, but diff"ering [from 

 Q IX of N. nilidieollis unknown to me)], by more robust form;
