ART. 6 NEW BUPRESTID BEETLES FROM COSTA RICA — FISHER 17 



suture between first and second segments not visible; vertical por- 

 tions of all segments except the second clothed with distinct spots 

 of white pubescence ; pygidium broadly sinuate at apex, but without 

 a projecting carina. Prosternum sparsely, coarsely punctate, more 

 finely anteriorly, and clothed with short, recumbent white hairs; 

 prosternal lobe broad, moderately declivous, and broadly, vaguely 

 emarginate in front; prosternal process broad, feebly expanded be- 

 hind 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 very 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 nearly sim- 

 ilar on all feet, cleft near middle, the teeth slender, and the inner 

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

 tips distant. 



Length, 11.75 mm. ; width, 2.75 mm. 



Type locality. — San Jose, Costa Rica. 



Type.— C2.t. No. 41611 U.S.N.M. 



Described from a single female collected on "guava leaves {Inga 

 sp.)" at the type locality, September 1, 1926, by Ferd. Nevermann. 

 This is not the guava found in the southern part of the United 

 States, which belongs to the genus Psidium and known under the 

 name of guava by the English-speaking peoples, but is the Spanish 

 name for various species belonging to the genus hiffa found in Cen- 

 tral America, where it is considered the best tree for shading the 

 coffee plants. 



TAPHROCERUS BREVICARINATUS, new species 



Elongate, more strongly attenuate posteriorly, moderately convex, 

 feebly flattened above, and nearly glabrous; above uniformly aeneous; 

 beneath piceous, with a strong aeneous tinge. 



Head much narrower than pronotum at base, strongly convex from 

 top to bottom, nearly flat transversely, the lateral margins vaguely 

 wider at top than bottom, and with a broad, longitudinal, very shal- 

 low concave depression extending from epistoma to middle of front ; 

 temple about one-third as wide as the transverse diameter of the eye ; 

 surface obsoletely reticulate, and glabrous. 



Pronotum moderately convex, nearly twice as wide as long, dis- 

 tinctly wider at base than apex, and widest at base; sides when 

 viewed from above obliquely expanded from apical angles to pos- 

 terior angles, which are nearly rectangular; anterior margin trans- 

 versely truncate ; base transversely truncate to middle of each elytron, 

 with the median lobe feebly produced and vaguely emarginate in 

 front of scutellum; disk with a narrow transverse depression behind 

 the anterior margin, broadly depressed along lateral margins, and
