thorax combined, two-fifths longer than prothorax, defiexed at basal 

 third, in dorsal view attenuate from laterally expanded antennal in- 

 sertion to near apex; basal two-thirds dull, alutaceous, sparsely punc- 

 tured, apical third smooth, shining. Antennae of male inserted at 

 basal third of beak at distance from eye one-third greater than width 

 of frons; first and second segments each shorter than next two, club 

 0.17 by 0.07 mm. Eyes moderately prominent ; frons wider than dorsal 

 tip of beak. Prothorax at base one-fifth wider than long, middle 

 narrower than base, apex three-fourths as wide as base; sides beyond 

 slight basal lateral expansion nearly parallel to middle, rounded to 

 constricted apex; in profile dorsal surface nearly flat; punctation 

 moderately deep, 0.02 mm. in diameter, interspaces about equal to 

 diameter of punctures; basal fovea shallow, punctiform. Elytra at

humeri one-third wider than prothorax at base; nearly three times as 

 long as prothorax, length to width as 15 : 12.5; intervals about tudce 

 as wide as striae, nearly flat, with one row of fine scales; striae moder- 

 ately deep, fine. Scutellum triangular, 0.07 by 0.06 mm., with a 

 shallow median furrow. Front femora about 3.3 times as long as wide. 

 Claws with acute basal tooth. 



Special male characters: Tibiae 2 and 3 armed with long, slender, 

 simple mucrones that project in line with the long axis of the tibiae; 

 tibia 1 with a smooth area extending two-thirds its length on front 

 inner surface, area iridiscent in certain light because of extremely fine, 

 densely placed striations. 



Female is unknown. 



Material examined: Type (MCZ 25109, in Fall Collection labeled 

 Nebraska) and four specimens.
