ART. 31 BUPRESTID BEETLES FROM BOLIVIA FISHER 41 



and the surface nearly smooth. Elytra moderately convex, wider 

 than pronotum at base, and widest just behind the middle ; humeral 

 angles broadly rounded; sides feebly expanded from base to just 

 behind the middle, then strongly arcuately attenuate to the tips, 

 which are conjointly, rather narrowly rounded, with the lateral 

 margins finely serrate to humeral angles; humeri strongly devel- 

 oped; each elytron with a broad, deep depression ut base, and a 

 narrow deeper one between the humerus and lateral margin, ex- 

 tending along the margin from the humeral angle to middle, and 

 broadly expanded behind the humerus; surface glabrous, rather 

 densely, coarsely and irregularly punctate, the intervals obsoletely 

 rugose toward the sides. Abdomen beneath finely and densely reticu- 

 late-striolate, with a few obsolete punctures intermixed, and without 

 distinct pubescence. Prosternum smooth and transversely sulcate 

 along anterior margin; prosternal process finely and sparsely punc- 

 tate, and sparsely clothed with moderately long recumbent brownish 

 hairs. Metasternum very coarsely and densely punctate, the punc- 

 tures shallow, oblong, and more or less confluent; anterior margin 

 deeply arcuately emarginate. 



Female. — Differs from the male in having the front of head fus- 

 cous, and the prosternal process smooth and not pubescent. 



Length, 3.25 mm. ; width, 2 mm. 



Type locality. — Canamina, Bolivia. 



Type, allotype and paratypes. — Cat. No. 26992, U.S.N.M. 



This species is described from a fairly large series of specimens 

 collected at the type locality during July, 1921. 



CALLIMICRA ACUMINATA, new species 



Male. — Oblong, moderately convex, broadly rounded in front, 

 strongly attenuate posteriorly, distinctly narrower behind than in 

 front, and moderately shining; head brilliant green, and feebly 

 cuperous on occiput; pronotum green, becoming more or less 

 cupreous and fuscous on disk; scutellum brownish-cupreous; elytra 

 black; beneath piceous. 



Head moderately convex, with a broad, shallow longitudinal 

 groove, extending from the occiput to middle of front, where it 

 terminates in a round shallow depression; surface densely, coarsely 

 granulose, with numerous large obsolete punctures intermixed; 

 antennae slightly aeneo-viridis. Pronotum moderately convex, two 

 times as wide as long, distinctly narrower in front than behind, and 

 widest along basal third; sides feebly arcuate from base to near 

 middle, then more arcuately attenuate to the anterior angles; pos- 

 terior angles rather acute ; anterior margin feebly arcuately emargi- 

 nate; base transversely sinuate to middle of elytron, then turning
