frons to slightly distad of middle, strongly attenuate, apical third 

 parallel-sided, less than two-thirds as wide as basal portion; in lateral 

 view stoutly parallel in basal half, greatly attenuate, apical third 

 nearly cylindrical; basal two-thirds with moderately dense, fine 

 punctures bearing fine pubescence, apical third smoother, glabrous, 

 more shining. Female beak one-fourth to one-third longer than head 

 and prothorax, moderately, evenly curved, slender; in dorsal view 

 basal fifth stout, nearly parallel-sided, equal to width of frons, abruptly 

 attenuate to basal third where it is about two-thirds as wide as at base, 

 apical two-thirds cylindrical; basal fifth dull, densely alutaceous, with 

 fine, dense punctures, pubescence scant, with deep, short lateral 

 furrow above antennal insertion; apical four-fifths polished, very 

 sparsely, minutely punctured. Antenna of male inserted at distance 

 from eye two-thirds greater than width of frons, slightly behind middle 

 of beak, of female at distance slightly greater than %vidth of frons, 

 at basal fifth of beak; first segment longer than next two, shorter
