 subequal. Body moderately stout, subparallel, pale brownish-testaceous 

 in color, the elytra still brighter and rather more rufous, the abdomen 

 piceous; prothorax rather small, slightly narrower than the elytra, 

 fully one-half wider than long, flaely, evenly and somewhat sparsely 

 punctured, the pubescence rather long, sparse but distinct; elytra at 

 the sides much longer than the sides of the prothorax, the suture 

 scarcely shorter than the median line, the punctures fine, subasperate 

 and only moflerately dense, the pubescence distinct; abdomen nearly 

 as wide as the elytra, narrowing slightly behind the middle, the punc- 

 tures fine, moderately close-set basally but becoming gradually very 

 sparse on the last four segments, the punctures of the impressions 

 slightly larger and rather less sparse than the others, and, as 

 usual, bearing only infinitesimal hairs; basal joint of the hind tarsi as 

 long as the next two combined. Length 2.9 mm. ; width 0.85 mm. New

8 — Larger and more convex, shining, black, the elytra and legs rather

 sparse and rather inconspicuous, fulvous as usual; head well developed, 

 three-fifths as wide as the prothorax, and, like the latter, finely and 

 sparsely punctulate; antennae scarcely as long as the head and pro- 

 thorax, gradually, strongly incrassate to the tip, compact, the tenth 

 joint three-fifths wider than long, the second and third elongate, the 

 former but slightly the shorter, prothorax large, less transverse, two- 

 flfths wider than long, moderately narrowed from base to apex with the 

 sides strongly arcuate, the base arcuate as usual, the angles very 

 obtuse but evident; elytra only two-fifths wider than long, the sides as 

 long as those of the prothorax, the suture three -fourths as long as the 

 median line, the punctures fine, feebly asperate and well separated; 

 abdomen nearly as wide as the elytra, parallel and straight at the sides, 

 not at all narrowed posteriorly from the base, finely, very sparsely 

 punctate; hind tarsi distinctly shorter than the tibiae, the basal joint 

 not quite as long as the next two combined. Length 3.8-4.4: mm.;

 larger, rounded and moderately sparse in the basal depressions; head 

 moderate, scarcely more than half as wide as the prothorax; antennae 

 less developed than in manner heimi, less incrassate, not quite as long 

 as the head and prothorax, the tenth joint scarcely more than a third 

 wider than long, the second much shorter than the third ; prothorax 

 short and strongly transverse, two-thirds wider than long, moderately 

 narrowed anteriorly and rather strongly rounded at the sides, the base 

 circularly arcuate; elytra strongly transverse, very slightly wider and
