[5. Stilpnochlora ovalifolia, sp. n. 



$ . Crassa, prasina. Staturae S. toltecce. Pronotum obscure viride (saltern postice) ; ejus discus latus, in lobo 

 antico ad occiput coarctatus ; sulcus anterior profundus, canthi ab illo distinctissime incisi ; canthi 

 prozonee inter sulcos per sulculos numerosos incisi, rotundato-multicrenulati. Sulcus posterior late 

 impressus, canthos insecans. Metazona brevis nigro-marginata, margine postico parum arcuato, marginibus 

 lateralibus superne verrucoso-crenatis. Elytra lata, quam in reliquis speciebus breviora, campo laterali 

 elliptico, margine infero sat fortiter arcuato, margine supero sicut in S. azteca arcuato ; quam in S. tolteca 

 apice minus truncate. Eamus venae principalis ante medium oriens. Campus analis (seu dorsalis) 

 elongatus crasse confertim punctatus. Tibiae antieae latere interno infra tympanum impressione profunda 

 notatae. Tibiae posticae graciles, sicut in S. tolteca, rectae vel subrectae. Ovipositor incurvus.

Hab. Brazil (Mus. Genavense). 



This species is remarkable on account of its wide form. The pronotum is broad 

 above, rather short. The elytra, also, are shorter and more rounded than in the other 

 species of the genus ; they are two and a half times the length of the dorsal field, 

 while in S. tolteca they are more than three times as long as the dorsal field ; the 

 dorsal field is elongate. In the form of the pronotum this species makes a sort of 

 transition to S. incisa ; but in the latter the margins of the anterior lobe are very 

 strongly trilobed, while in 8. ovalifolia they are only feebly cut by numerous small 

 sulci, and much less strongly crenulated than the margins of the posterior lobe.]
