formibus, ad apicem leniter compressis et incrassatis, articulo 

 primo incrassato, secundo brevi, tertio elongato, cseteria inter se 

 aequalibus, perparum leniter incrassatis ; palpis maxillaribus leni- 

 ter compressis, clavatis, articulo penultimo obconico, ultimo vix 

 latiore, hoc brevi, transverso, apice truncato. Thorax transversus, 

 apice late emarginatus. Elytra breviter ovata aut obovata, con- 

 vexa, thorace latiora, postice ssepe paullo angustata. Pedes sim- 

 plices. Mesosternum transversum, obliquum. Corpus ovatum, 

 convexum. 

 Type, Stilodes guttata, Baly. 



Nearly allied in form to Chrysomela, but easily separated from 

 that genus by the different form of the maxillary palpi together 

 with the shorter antennae. 



Stilodes guttata. 



S. ovata, convexa, rufo-fulva, nitida, oculis mandibularumque apice 

 nigris ; thorace longitudine fere triplo latiore, evidenter remote 

 punctato, punctis ad latera majoribus, valde impressis ; elytris 

 breviter ovatis, postice vix angustatis, convexis, utrisque lineis 1 1 

 e punctis impressis, harum prima abbreviata ; maculis 8 fulvis 

 instructis, duabus basalibus, duabus ante medium oblique, duabus 

 pone medium transversim, duabusque apicem versus longitudina- 

 liter, positis. — Long. 4 lin. 



Hab. Upper Amazons. 



Stilodes obsoleta. 



S. ovata, convexa, postice paullo angustata, nitido-rufo-fulva, anten- 

 nis extrorsum nigris ; thorace longitudine plus duplo latiore, remote 

 tenuiter, lateribus magis distincte punctato ; elytris seriatim punc- 

 tatis, utrisque maculis septem obsolete fulvis, duabus baseos, 

 duabus ante, duabus pone medium et una ante apicem, positis. — 

 Long. 4 lin. 



Hab. Ega, Upper Amazons. 



Narrower than the preceding species. 



Stilodes fenestrata. 



S. ovata, convexa, fulva, nitida ; thorace subremote punctato, nigro, 

 lateribus fulvis ; elytris breviter ovatis, postice paullo angustatis, 

 convexis, utrisque lineis 11 e punctis leniter impressis, harum 

 prima abbreviata, punctis in striis confuse dispositis ; plagis magnis 

 tribus superficiem fere amplectentibus, nigris, prima transversa 

 basi, secunda late transversa supra medium, tertiaque trigona api- 

 cem versus, positis, pleuris remote punctatis, nigris. — Long. 4 lin. 



Hab. San Paulo, Upper Amazons.
