cence moderately long and coarse, evenly distributed and rather sparse. Head 

 three-fonrths as wide as the prothorax, densely punctato-rugose, the punctures 

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

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

 sirbcoriaceous; labrum dark; eyes rather prominent; an tenuai distinctly longer 

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

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

 verse, three-fifths wider than long, narrowly rounded and Avidest 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 and sculptured like the head. 

 Elytra short, oblong, parallel, barely two-thirds longer than wide, not evi- 

 dently wider than the prothorax, oljtusely parabolic in apical third, the imnc- 

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

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

 width 0.9 mm.

Allied to c/rt»JiCor»«.s, but distinguishable at once by its slightly 

 denser vestiture, much broader prothorax, less clavate antennoe 

 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 finely reticulate interspaces and feeble aeneous 

 lustre, the elytra with dull but indefinitely sculptured interspaces 

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

 evenlj^ distributed and decumbent. Head three-fourths as wide 

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

 sions feeble; epistoma short, transverse, pale and coriaceous; 

 eyes prominent, rather small; antennae slender, nearl}^ one-half 

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

 joint one-third wider than long. Prothoraxabout 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, obtusely 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-
