NEW BUPRESTID BEETLES — FISHER 329 



POLYCESTA BRUNNEIPENNIS, new species 



Female. — Broadly elongate, broadly rounded in front and behind, 

 moderately convex above; head, pronotum, scutellum, and underside 

 of body black, elytra reddish brown, usually with the longitudinal 

 costae blackish. 



Head in front flat, without depressions, coarsely, deeply, confluently 

 punctate, sparsely clothed with short, erect, inconspicuous hairs; 

 epistoma broad, truncate in front. 



Pronotum strongly transverse, twice as wide as long, distinctly 

 narrower in front than behind, widest at basal third; sides strongly 

 diverging from apical angles to basal thirds, where they are obtusely 

 angTilated, then obliquely converging to posterior angles, which are 

 rectangular; anterior margin deeply, arcuately emarginate, with a 

 feeble, broadly rounded median lobe, and the margin smooth and 

 narrowly elevated ; base sinuate, with the median lobe feebly, broadly 

 rounded; disk with a broad, shallow, median depression; surface 

 densely, coarsely, deeply punctate, punctures more or less confluent 

 toward sides, each puncture with a short, inconspicuous hair, the 

 intervals smooth. Scutellum small, nearly round, smooth. 



Elytra slightly wider than pronotum at base ; humeral angles broadly 

 rounded ; epipleural lobes not dentate at apices ; sides nearly parallel 

 anteriorly, broadly expanded behind middles, then arcuately converg- 

 ing to the tips, which are acute, the margins slightly serrate near 

 apices. Each elytron with five longitudinal costae, the presutural 

 costa extending from base to basal third; two distinct median ones 

 extending from base to apex ; and two more or less distinct prelateral 

 costae interrupted anteriorly and posteriorly, and with nine rows of 

 coarse punctures aranged in double rows (except lateral row) between 

 the costae, the punctures deep and variable in size; intervals very 

 sparsely, finely, irregularly punctate, with a few very short, incon- 

 spicuous hairs. 



Abdomen beneath rather densely, finely punctate, sparsely clothed 

 with short, recumbent hairs; intervals smooth and shining; first 

 sternite strongly convex at middle; last visible sternite narrowly 

 rounded at apex. Prosternum strongly convex, coarsely punctate, 

 more or less confluently toward sides, sparsely clothed with short, 

 recumbent hairs; anterior margin truncate, feebly elevated; pro- 

 sternal process short, broad, nearly flat, without marginal grooves, 

 sides nearly parallel to behind coxae, broadly rounded at apex. 



Male. — Differs from the female in being usually smaller, slenderer, 

 and in having a denselj'- punctured and pubescent spot on the median 

 part of the first abdominal sternite. 



Length 16-23 mm., width 6-9 mm. 



Type locality. — Barranquilla, Colombia. 



Type^ allotype^ and paratypes. — U.S.N.M. No. 58783.
