340 A Preliminary Monograph of the 



Head faur-fifths as wide as the prothorax, feebly convex, finely, rather 

 feebly, very densely punctate ; prominences short, strong ; antennae 

 moderate, feebly incrassate ; joints two to four almost uniformly and 

 very rapidly decreasing in length, tenth slightly longer than wide ; eyes 

 large and comparatively finely granulated, slightly prominent ; tempora 

 one-third as long, strongly. rounded, not angulate. Prothorax one-half 

 wider than long, widest at anterior third, where the sides are broadly 

 rounded, thence feebly convergent and feebly arcuate to the apex, and 

 much more strongly convergent and scarcely perceptibly arcuate to the 

 base ; the latter broadly arcuate, three-fourths as wide as the disk, nar- 

 rower than the apex which is transversely truncate ; apical angles 

 obtuse, very narrowly rounded ; basal obtuse and more broadly rounded; 

 disk rather densely punctate, shining in the middle, dull at the sides ; 

 punctures in the middle very fine and separated by twice their own 

 widths, gradually coarser laterally, and, near the sides, very large, 

 shallow, variolate and polygonally crowded ; median impressions mod- 

 erate ; not impressed laterally. Elytra quadrate, very slightly wider 

 and nearly one-half longer than the prothorax, distinctly impressed near 

 the suture, rather coarsely, feebly punctate ; punctures separated by 

 fully their own diameters. Abdomen parallel, slightly narrower than 

 the elytra ; sides feebly arcuate ; border moderate in width and depth ; 

 surface finely subgranulose, shining, minutely and not very densely 

 punctate. Legs slender. Length 3.0 mm. 



California (San Mateo Co. 2). Mr. C. Fuchs. 



This is a very distinct species in pronotal sculpture. 



A specimen from Humboldt Co. agrees very well, differing only 

 in having the prothorax a little shorter, with the sides slightly 

 less strongly convergent toward base, but it also appears to differ 

 sexually.

 Soc, IV., p. 459.— Moderately robust and convex, black; legs piceous; 

 knees and tarsi paler; antennae piceous throughout; pubescence mode- 

 rate, rather coarse, and sparse, erect; integuments shining. Head 

 nearly one-third narrower than the prothorax, rather finely, feebly, 

 and moderately densely punctate, shining; antennal prominences 

 strong, moderate in length; antennae slender, distinctly longer than the 

 head and prothorax; club gradual and very slight; second and third 

 joints equal, elongate, third shorter and shorter than the fourth, tenth 

 distinctly longer than wide; eyes very large and prominent; tempora 

 almost obsolete behind them, reduced to a very short point. Prothorax 

 nearly two-thirds wider than long, widest near apical third, where the 

 sides are rather strongly rounded, thence strongly convergent and 

 straight to the base, also strongly convergent and distinctly arcuate to
