segments, and sparsely clothed with short, inconspicuous hairs; first 

 and second segments convex at middle, and without a median de- 

 pression; last segment broadly rounded or subtruncate at apex, and 

 with a fringe of long hairs; vertical portions of the segments not 

 conspicuously pubescent; pygidium sparsely, coarsely punctate, with 

 a vague longitudinal carina, but the carina not projecting. Prester- 

 num finely granulose, sparsely punctate, and sparsely clothed with 

 short, inconspicuous hairs; prosternal lobe broad, strongly declivous, 

 and broadly rounded or subtruncate in front; prosternal process 

 rather narrow, the sides parallel to behind the coxal cavities, then 

 obliquely narrowed to the apex, which is acute. Posterior coxae with 

 the posterior margin broadly, arcuately emarginate, and the exterior 

 angle rectangular. Tibiae slender, straight, and without a distinct 

 tooth 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 at middle, the outer tooth acute at apex, 

 the inner one slightly broader, turned inward, and the tip sometimes 

 touching that of the opposite side. 



Length, 4.75 mm.; width, 1.125 mm. 



Male. — Differs from the female in having the front of head bronzy 

 green to greenish blue, not so strongly convex, surface more dis- 

 tinctly granulose, and rather densely clothed on lower half with 

 long, white pubescence, which does not conceal the surface; first 

 two abdominal segments feebly flattened at middle, but not pubes- 

 cent; last abdominal segment truncate at apex, and clothed with a 

 dense marginal fringe of long, reddish brown hairs, which are curved 

 and directed downward, and all tibiae with a distinct tooth on inner 

 margin at apex.
