406 Mr. J. S. Baly on new Genera and Species of Gallerucidae. 



Dircema discoidale, 



D. elongatum, couvexum, dorso subdeplanatum, flavum, nitidum, 

 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 paralleUs, 

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

 nitidis, pube brevissima vestitis, sutura anguste margineque flavis ; 

 feraoribus quatuor anticis dorso fusco-lineatis. 

 Mas. CEdeagus basi incrassatus, curvatus, lateribus parallelis, apice 



ovato-lanceolatus, apice ipso producto, recto, truncato. 

 Long. 5 lin. 



Hab. Nauta, Peru. 



Forehead impressed with a large obovate depression, coarsely 

 punctured, sparingly clothed with coarse hairs; eyes ovate- 

 rotundate ; four upper joints of antennse 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. 

 D. 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 

 fulvis. 

 Foem. Abdominis segmentum anale apice obtuse angulatum, medio 



vix emarginatum. 

 Long. 3^4f lin. 

 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 antennse obscure fusco-fulvous. Thorax 

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