Dircema discoidale. 



D. elongatum, convexum, dorso subdeplanatum, flavum, nitidurn, 

 vertice, fronte, mandibulis antennisque nigris, his apice sordide 

 albidis ; thorace longitudine plus duplo latiore, lateribus ante me- 

 dium modice ampliatis, transversim sulcato, utrinque foveolato, 

 dorso fere glabro, remote punctato, nitido, nigro, marginibus basali 

 et laterali flavis ; elytris thorace multo latioribus, fere parallelis, 

 convexis, dorso subdepressis, granulosis, metallico-cyaneis, sub- 

 nitidis, pube brevissima vestitis, sutura anguste margineque flavis; 

 feraoribus quatuor anticis dorso fusco-lineatis. 

 Mas. (Edeagus basi incrassatus, curvatus, lateribus parallelis, apice 



ovato-lauceolatus, apice ipso producto, recto, truncate 

 Long. 5 lin. 



Hab. Nauta, Peru. 



Forehead impressed with a large obovate depression, coarsely 

 punctured, sparingly clothed with coarse hairs; eyes ovate- 

 rotundatc ; four upper joints of antennae pale fulvous. Apical 

 border of thorax concave, entire, side-margin moderately dilated 

 in front, nearly straight and parallel behind, hinder angles 

 acute; disk shining, sparingly clothed with suberect hairs; 

 transverse excavation broad, less deeply impressed than in most 

 of the other species; it is, however, rendered deeper on either 

 side by a large roundish fovea, which is placed about halfway 

 between the middle and the lateral border. Elytra shorter than 

 in the other species, much broader than the thorax, depressed 

 above. 



My collection contains two male specimens of this species. 



Dircema laticolle. 



I), elongatum, parallelum, convexum, fulvo-flavum, nitidum, capite 

 (facie inferiore excepta) nigro, antennarum articulis tribus ultimis 

 sordide flavis ; thorace brevi, longitudine triplo latiore, lateribus 

 ante medium late explanatis, disco minus crebre, medio subremote 

 punctato, pube depressa nigra sparsius vestito, profunde trans- 

 versim excavato, pone sulcum distincte elevato ; elytris nigris, 

 opacis, rude granulosis, pube adpressa fusca aut nigra vestitis, 

 sutura margineque flavis ; pedibus nigris, femoribus basi et infra

Hab. Amazons. 



Forehead depressed, rugulose, vertex nitidous; epistome im- 

 pressed with a deep longitudinal groove, which extends from the 

 apical border to the encarpse, its upper half very strongly marked; 

 three upper joints of antennae obscure fusco-fulvous. Thorax 

 short, quite thrice as broad as long; apical margin concave,
