NORTH AMERICAN COLEOPTERA. 287 



This species may be readily knowu by its small size, almost true 

 black color and very coarsely punctate elytra, the entire surface 

 without metallic lustre. 



Occurs in Sumter Co., Fla., on a species of SoUdago (Schwarz). 



22. \j. niti«lelliis Cockerell. — Oblong oval, convex, piceous, surface dis- 

 tinctly bronzed, shining. Antennsp, longer than half the body, slender, rufotes- 

 taceous at base, piceous externally. Head impunctate. Thorax a little wider 

 than long, not narrowed in front, base broadly arcuate, hind angles rounded, 

 sides feebly arcuate, anterior angles obliquely truncate, with distinct post-apical 

 angulation, disc convex, distinctly alutaceous, the punctures moderate, neither 

 deep nor closely placed, finer in front. Elytra not wider at base than the thorax, 

 humeri oblique, umbone wanting, form regularly oval, broadest at middle, 

 apices separately rounded, tip of pygidium exposed, disc convex, the punctuation 

 rather coarse and close at base, gradually finer toward apex and sides. Body 

 beneath piceous, less shining. Abdomen alutaceous, rugose, the punctures coarse 

 and close, but shallow. Legs rufotestaceous, the posterior femora much darker. 

 Length .08 inch. ; 2 mm. 



In the male the last ventral segment is truncate at apex and with 

 a small, smooth tubercle at middle of disc 



As the bronze surface is Dot a common character among our spe- 

 cies there need be no difficulty in distinguishing this by its apterous 

 form, obliterated humeri and rounded tips of elytra. 



This species was rather imperfectly described by Mr. Cockerell in 

 a little sheet which may not fall in the hands of many students. 

 Through his kindness I possess the specimen described, and am able 

 to fix its specific relationships with greater certainty. 



Occurs in Arizona, New Mexico and Colorado. 



23. \j, inaiicu^i Lee. — Oblong oval, convex, piceous, surface distinctly 

 bronzed and shining. Antennae longer than half the body, piceous, the outer 

 six joints distinctly stouter, joints 2-3-4 equal in length. Thorax very little 

 wider than long, not narrowed in front, base broadly arcuate, hind angles very 

 obtuse, sides feebly arcuate, front angles slightly obliquely truncate, disc moder- 

 ately convex, punctuation sparse and indistinct, at apex smoother, base without 

 marginal line. Elytra not wider than the thorax, humeri entirely obliterated 

 no umbone, sides arcuate, gradually wider posteriorly, obliquely truncate at apex 

 leaving the entire pygidium exposed, disc convex, sparsely, finely and indistinctly 

 punctate. Body beneath piceous, shining Abdomen sparsely, indistinctly punc 

 tate. Legs piceous, posterior femora bronzed, the tibije pale brown or testaceous 

 Length .06 inch. ; 1.5 mm. 



This species, which is one of the smallest in our fauna, is readily 

 known by the truncate elytra, bronzed and nearly smooth surface 

 The general apj)earance is that of a minute Meloe. The body is en 

 tirely apterous and the metasteriium (juite short. 



Occurs in California.
