Sterna more or less obsoletely punctate and very feebly rugulose. 



Parapleurce coarsely and somewhat obsoletely punctate. 



Ahdomen horizontal, quite smooth, very finely and sparsely punc- 

 tulate, finely rugulose. 



Legs rather long and slender. Anterior femora more or less 

 armed; anterior tibial spurs subequal and rather stout. Tarsi similar

Male. — Body moderately slender, antenna? attaining the base of the 

 prothorax. Elytra produced at tip forming a cauda, which is nearly 

 horizontal and 4 mm. more or less in length, with its inferior surface 

 formed by the general internal surface of the elytra. Abdomen

 10-10.8 mm. Females: Unknown to me. 



Genital characters., male. — Edeagophore elongately fusiform, not 

 arched. 



Basale elongate oblong, very moderately convex, with sides slightly 

 arcuate. 



Apicale elongate, triangular, nearly twice as long as wide, mod- 

 erately convex above, groove very fine and linear; sides feebly 

 arcuate, just noticeably sinuate in apical half, tip subacute; base with 

 a broad rounded lobe at central two-fourths, laterally feebly sinuate. 



Sternite transversely parabolic. Each lobe rather short, with the 

 external border evenly arcuate and continuously so with the apical 

 border, which is rather broadly arcuate, angle not evident; internal 

 border short, feebly arcuate or straight; surface feebly convex, 

 sparsely punctate and setose, setae quite long, longer and denser

 apical angles very acute and in the form of small everted teeth ; base 

 very feebly arcuate; basal angles extremely obtuse; sides almost 

 evenly and distinctly arcuate; disc widest just Adsibly before the 

 middle, rather strongly and evenly convex, minutely and very 

 sparsely punctate. Elytra with humeri not prominent; disc with 

 distant unimpressed rows of fine simple moderately approximate
