Prothorax about as wide at base as at apex 1 1 



7 Sides of the prothorax very oblique and evidently sinuate posteriorly. 

 Form subparallel, distinctly convex, highly polished, the elytra with- 

 out trace of minute sculpture; color rufo-testaceous, the head and a 

 large central elytral cloud piceous, the latter forming a broad fascia 

 which envelopes the side margins; legs flavate; head well developed, 

 nearly four-fifths as wide as the prothorax, the eyes moderate but 

 prominent; sulci deep, remote, perfectly parallel; antennae slightly 

 longer than the elytra, infuscate, flavate apically and at base, the 

 second joint much longer than the third; prothorax four-fifths wider 

 than long, the sides strongly rounded anteriorly, very oblique bas- 

 ally and slightly sinuate before the obtuse but prominent and greatly 

 reflexed angles; margins well reflexed throughout; subbasal impres- 

 sion deep, angulate; base much narrower than the apex; elytra one- 

 half longer than wide, barely a third wider than the prothorax; 

 sides feebly arcuate; humeri distinct; first and second striae distinct, 

 subequal, all the others obsolete, except the third which is visible 

 basally; anterior fovea near basal third. Length 1.8-2.0 mm.; 

 width 0.72-0.75 mm. Isthmus of Panama -(Colon), Beaumont. 



*beaumonti n. sp. 

 Sides of the prothorax very moderately oblique behind and not evidently 



sinuate before the basal angles 8 



8 Head unusually large, about as wide as an elytron 9 



Head moderate, always distinctly narrower than an elytron 10 



9 Form elongate, barel}' at all ventricose, polished, rather convex, the 

 pronotum without minute sculpture, the elytra with extremely fine, 

 close and feeble strigilation; head blackish, the prothorax pale flavo- 

 testaceous, the elytra uniform pale brown; under surface and legs 

 very pale testaceous; head four-fifths as wide as the prothorax, with 

 moderate, prominent eyes, the sulci not very remote, parallel; an- 

 tennae as long as the elytra, brown, flavate at base and tip; prothorax 

 almost one-half wider than long and barely narrower at base than at 

 apex, widest at two-fifths from apex, the sides broadly, subevenly 

 rounded, less so basally, with the obtuse angles moderately reflexed, 

 their apices only minutely prominent; subbasal impression peculiar, 

 being rather coarse and close to the basal margin; elytra one-half 

 longer than wide, not quite one-half wider than the prothorax, just 

 visibly wider behind the middle than at base, the humeri distinct; 

 pedicel two-fifths the basal width; sutural stria deep and conspicu- 

 ous, the second barely traceable, the others obsolete; anterior fovea 

 near two-fifths. Length 2.4 mm.; width 0.8 mm. North Caro- 

 lina (Southern Pines), -Manee columbiensis Hayw. 



Form rather less parallel, not so convex, not very shining, the elytra pol- 

 ished, the ground sculpture extremely minute on the pronotum and 

 elytra; color blackish-piceous, the prothorax obscure rufous; under 

 surface piceous, the legs pale flavate; head large, only very slightly 

 narrower than the prothorax, the eyes unusually large and prom- 

 inent, separated by between two and three times their width, the 

 sulci moderate, rather distant; surface strongly micro-reticulate; 

 antennae slender, fully as long as the elytra, blackish, the basal
