380 PROCEEDIK'GS OF THE NATIONAL MUSEUM vol.94 



Elytra equal in width to pronotiiin, and 1.26 times as long, 1.08 

 times as long as wide ; bases bisinuate, sides neai-ly straight and sub- 

 parallel on anterior half, then gradually, arcuately narrowed, mod- 

 erately rounded behind ; disk short, comprising only about two-fifths 

 of the total length of elytra, surface brightly shining; strial punctures 

 small, in fairly regular rows, striae not impressed; interspaces flat, 

 with a few very minute punctures, apparently glabrous, the first and 

 second interspaces each ending in a tooth extending caudad over the 

 excavated anterior portion of the declivity, that from the first inter- 

 space being longer and sharper. Declivity originating in the recess 

 formed by the overhanging posterior edge of the discal portion, slop- 

 ing, arcuate ; strial punctures in imperfect rows ; interspaces rugulose, 

 each with a median row of granules, from which arise yellow hairs, 

 long and slender near summit, stouter and spatulate toward apex; 

 posterior lateral border with a rather fine beaded margin. 



Type locality. — Panama Canal Zone. 



Host. — Unknown. 



Type ma^ena/.— Holotype, U. S. N. M. No. 56556. 



The holotype was collected "from felled tree," August 19, 1923, 

 by J. Zetek. 



Genus CERATOLEPIS Chapuis 



CERATOLEPIS NUBILUS, new species 



Male. — Reddish brown, infumated with piceous; 2.14 mm. long, 

 2.34 times as long as wide ; allied to G. errans Blandf ord. 



Frons distinctly concave; surface finely, closely punctured, with 

 numerous short, rather stout, light-cinereous hairs, evenly distributed 

 over concavity; epistomal margin strongly incurvate. Eye slightly 

 wider above, lower end not angulate, inner line entire, facets rather 

 large. Antenna similar to that of errans. 



Pronotum almost exactly as long as wide, posterior outline nearly 

 straight, with distinct, beaded margin, posterior lateral angles 

 rounded; sides arcuate from base to apex, with beaded margin extend- 

 ing four-fifths of distance from base, anterior margin moderately 

 broadly rounded; surface weakly shining, punctures deep, rather 

 close, closer at sides and in front ; subglabrous, median line narrowly 

 impunctate behind, not elevated. 



Elytra very slightly wider than pronotum and 1.43 times as long, 

 1.34 times as long as wide; bases weakly arcuate, sides straight and 

 subparallel on anterior two-thirds, moderately narrowly rounded 

 behind; surface moderately shining, strongly sculptured; striae im- 

 pressed, punctures close and large near base, smaller behind ; inter- 

 spaces much wider than striae, convex, strongly rugose, with uniseri- 

 ate punctures nearly as large as those of striae on anterior half.
