ART. 6 NEW BUPKESTID BEETLES FROM COSTA RICA FISHER 5 



first segment convex and without long pubescence at middle; last 

 segment rather acutely rounded at apex; suture between first and 

 second segments not visible ; vertical portions of the third and fourth 

 segments clothed with a more or less distinct pubescent spot; 

 pygidium rather strongly carinate anteriorly, but the carina not pro- 

 jecting at apex. Prosternum sparsely, coarsely punctate, more finely 

 anteriorly, and sparsely clothed with short, inconspicuous hairs ; pros- 

 ternal lobe broad, moderately declivous, and broadly rounded in 

 front; prosternal process broad, expanded behind the coxal cavities, 

 then abruptly narrowed to the apex, which is bent upward and acute. 

 Tibiae slender, the anterior pair slightly arcuate, and armed with a 

 short tooth on inner margin at apex. Posterior tarsi distinctly shorter 

 than tibiae, and the first joint as long as the following three joints 

 united. Tarsal claws cleft near middle, the teeth slender, and the 

 inner ones slightly shorter than outer ones, and turned inward, but 

 their tips distant (claws missing on posterior tarsi).

 bottom to top, and with a very broad, shallow concave depression 

 extending from occiput to epistoma ; surface finely granulose, rather 

 densely, coarsely punctate, somewhat rugose, and with a few white 

 hairs behind the epistoma; epistoma not transverse between the 

 antennae, broadly, arcuately emarginate in front, and the surface 

 coarsely rugose; antennae extending about to middle of pronotum, 

 serrate from the fourth joint, and the outer joints as wide as long; 

 eyes large, broadly oblong, and equally rounded above and beneath. 



Pronotum slightly wider than long, slightly wider at apex than
