ABT. 6 NEW BUPKESTID BEETLES FROM COSTA RICA FISHER H 



coarsely, densely, irregularly rugose, and with numerous fine punc- 

 tures between the rugae; epistoma strongly transverse between the 

 antennae, and broadly, vaguely, arcuately emarginate in front; 

 antennae extending to middle of pronotum, serrate from the fifth 

 joint, and the outer joints slightly wider than long; eyes moderately 

 large, not very broadly oblong, but slightly more acutely rounded 

 beneath than above. 



Pronotum about one-third wider than long, distinctly wider at apex 

 than base, and widest near apex; sides feebly arcuately narrowed 

 from apical angles to behind middle, then more strongly narrowed 

 to the posterior angles, which are rectangular; when viewed from 

 the side the marginal and submarginal carinae are strongly sinuate, 

 widely separated anteriorly, and connected to each other behind 

 the middle; anterior margin strongly sinuate, the median lobe mod- 

 erately produced and broadly rounded ; base broadly arcuately emar- 

 ginate at middle of each elytron, the median lobe slightly pro- 

 duced, and arcuately emarginate in front of scutellum; disk with 

 two broad, shallow median depressions, a rather narrow depression 

 on each side along lateral margin, and with strongly elevated, slightly 

 arcuate prehumeral carinae extending from posterior angles to basal 

 third, but not connected to the marginal carinae; surface coarsely, 

 closely, transversely rugose at middle, more obliquely rugose at the 

 sides, finely, sparsely punctate between the rugae, and clothed with 

 a few short yellow hairs in the lateral depressions near apical angles. 

 Scutellum strongly, transversely carinate, and the surface finely 

 reticulate. 



Elytra slightly wider than pronotum at base, and about equal in 

 width at base and behind middle; sides nearly parallel for a short 

 distance behind base, vaguely arcuately constricted in front of mid- 

 dle, feebly arcuately expanded behind the middle, then obliquely 

 narrowed to the tips, which are separately narrowly rounded, and 

 strongly serrulate; disk vaguely flattened, without longitudinal 

 costae, sutural margins slightly elevated posteriorly, and with broad, 

 shallow basal depressions ; surface densely, finely imbricate-punctate, 

 sparsely clothed with short inconspicuous hairs, and each elytron 

 ornamented with a broad vitta of sparsely placed, short yellowish 

 hairs, the vitta not very conspicuous, and extending from the basal 

 depression to near the apex. 



Abdomen beneath obsoletely granulose, finely, rather densely punc- 

 tate, the punctures more or less connected transversely on basal seg- 

 ment by sinuate lines, and sparsely clothed with very short, recumbent 

 whitish hairs; sides rather broadly exposed above; first segment 

 convex and without long hairs at middle ; last segment rather broadly 

 rounded at apex; suture between first and second segments not vis- 

 ible ; vertical portions of the segments slightly more densely pubescent
