cence moderately loug aud coarse, evenly distributed and rather sparse. Head 

 three-fourths as wide as the prothorax, densely puuctato-rugose, the punctures 

 shallow; anterior impressions ■ moderate, separated at the frontal margin by a 

 shining impunctate space; epistoma narrow, polished, impunctate, pale and 

 subcoriaceous; labrum dark; eyes rather prominent; antenna; distinctly longer 

 than the prothorax, somewhat slender, the fifth joint dilated as iisnal, club 

 feeble, the tenth joint almost as long as wide. Prothorax short, strongly trans- 

 verse, three-fifths wider than long, narrowly rounded and widest near the base, 

 the sides thence strongly convergent and nearly straight to the obtuse apical 

 angles; apex feebly arcuate, the base broadly, almost evenly and more strongly 

 arcuate; disk broadly and evenly convex, dull Jind sculptured like the head. 

 Eli/tra short, oblong, parallel, barely two-thirds longer than wide, not evi- 

 dently wider than the prothorax, obtusely parabolic in apical third, the punc- 

 tures strong, rather coarse and moderately close-set. Abdomen feebly sculp- 

 tured and rather shining, the legs moderate in length. Length 2.4 mm.; 

 width 0.9 mm.

Allied to e/a»Jtcor/u'8, but distinguishable at once by its slightly 

 denser vestiture, much broader prothorax, less clavate antennae 

 with a decidedly less transverse tenth joint, and by the broadly 

 impressed sulcus of the genital segment; the fifth ventral of the 

 male is truncate at apex, with the surface broadly flattened and 

 normalh^ pubescent. A single male.

Rather stout, suboval, convex, black throughout, the head and 

 pronotum with finel}^ reticulate interspaces and feeble jeneous 

 lustre, the elytra with dull but indefinitely sculptured interspaces 

 and a feeble bluish tinge ; pubescence extremely short, remote, 

 evenly distributed and decumbent. Head three-fourths as wide 

 as the prothorax, quite finely and sparsely punctate, the impres- 

 sions feeble; epistoma short, transvei'se, pale and coriaceous; 

 eyes prominent, rather small ; antennje slender, nearly one-half 

 longer than the prothorax, the three-jointed club feeble, tenth 

 joint one-third wider than long. Prothorax about one-third wider 

 than long, the sides subparallel, evenly arcuate; punctures small, 

 deep and sparse, the sculpture rugose near the sides. Elytra 

 oval, one-half longer than wide, nearly one-half wider than the 

 prothorax, obtusel}' ogival at apex, broadly sinuate at base, the 

 humeri anteriorly and obtusely prominent; sides parallel and 

 broadly arcuate; disk rather finely and sparsely, feebly but sub-
