tips which are separately, narrowly rounded, and rather coarsely ser- 

 rulate ; sides of abdomen narrowly exposed above ; disk feebly, longi- 

 tudinally depressed along sutural margins at middle, sutural margins 

 rather strongly elevated from basal third to apex, and with broad, 

 shallow basal depressions; surface coarsely, densely imbricate-punc- 

 tate, sparsely clothed with short, inconspicuous hairs posteriorly, 

 and each elytron ornamented with three whitish pubescent spots, one 

 in basal depression, one in front of middle, and the other at apical 

 third. 



Abdomen beneath obsoletely reticulate, finely, sparsely punctate, 

 the punctates connected transversely by more or less distinct sinuate 

 or crenulate lines, which are coarser on the basal segments, and 

 sparsely clothed with short, recumbent, white hairs ; first and second 

 segments broadly, longitudinally concave at middle; last segment 

 broadly rounded or subtruncate at apex, with a few coarse granules 

 near the posterior margin; vertical portions of segments slightly 

 more pubescent than ventral surface; pygidium vaguely punctate, 

 and feebly carinate, but the carina not projecting. Presternum 

 sparsely, coarsely punctate, more or less rugose, and rather densely 

 clothed at middle with long, erect, fine, whitish hairs, which extend 

 along the middle of body to the posterior margin of second abdomi- 

 nal segment; prosternal lobe broad, slightly declivous, and feebly, 

 broadly emarginate in front; prosternal process broad, the sides 

 parallel to behind the coxal cavities, then abruptly narrowed to the 

 apex, which is acute. Tibiae slender, the anterior and middle pairs 

 slightly arcuate, and armed with a distinct tooth on inner margin at 

 apex. Posterior tarsi about as long as the tibiae, and the first joint 

 as long as the following three joints united. Tarsal claws similar on 

 all feet, cleft near the middle, the inner tooth broad, shorter than 

 outer one, and not turned inward. 



Length, 4.75 mm. ; width, 1.2 mm. 



Female. — Differs from the male in having the head slightly more 

 bronzy green, and the surface more strongly rugose; antennae not 

 extending to posterior angles of pronotum ; first and second abdomi- 

 nal segments not depressed or densely pubescent at middle; pres- 

 ternum without long, erect pubescence; posterior tarsi not as long as 

 tibiae, and the tibiae unarmed at the apex. 



Redescribed from the male type in the collection of J. N. Knull. 



Type locality. — " C. Missouri."
