2 . Profunde prasina. Caput triangulare, oculis valdo tumidis. Scutellum faciale quam altior sesquilatior, late 

 pentagonalis, margine supero valde obtusangulo, angulo rotundato, angulis lateralibus rotundatis, marginibus 

 lateralibus parallelis. Ocelli minuti in trigonum latissimum brevissimum exserti. Pronotum robustum, 

 latissime dilatatum; latius quam longius, rotundato-pentagonale, antice supra caput valde excisum ; 

 emarginaturae margo bisinuatus, angulis utrinque acute obtusis. Scuti margo anterior utrinque sub- 

 arcuatus, subtilissime crenulatus ; margo posterior transversus, rectus. Anguli laterales et posteriores 

 valde rotundati. Superficies utrinque lineis 3-5 arcuatis, subprominulis, marginibus externis plus minus 

 parallelis, obferens. Puncti 2 impressi in tertia parte, sulcus in quarta parte anteriore pronoti perspicui. 

 Elytra abdomen superantia, opaca, ovato-lanceolata, recta, foliam symetricam simulantia. Eorum margo 

 costalis et suturalis aequaliter arcuatus ; campus marginalis baud dilatatus, quartam partem latitudinis 

 elytri efficiens ; campus discoidalis maculam callosam albidam ante tertiam partem longitudinis ad venam 

 mediam positam prsebens ; venae discoidales oblique pectinatse. Alae hyalinse, ad marginem costalem basi 

 et apice virescentes ; margo costalis apice sat fortiter arcuatus ; apex 5 obtusus, $ modice acutus. Pedes 

 antici mediocres. Coxae in marginibus omnibus spinulosee. Femora latere interno macula nigra ovali ultra 

 incisuram posita, necnon punctis nigris in basi spinarum majorum intercalatarum ; spinse apice nigrae ; 

 margo externus spinis 4. Tibiae spinis 14 : 14. 



<J . Scutellum faciale paulo magis pentagonale, paulo minus altum quam in $ . Ocelli in trigonum fere 

 eequilaterale exserti, Pronoti folia minus grandis, rbomboidalis ; ejus diagona linea paulo ante medium 

 transcurrens ; ejus margo posterior truncatus, minus latus quam emarginatura antica ; ejus margines 

 latero-postici vix arcuati, usque ad alas convergentes. Elytra quam in $ longiora ac angustiora, stigmate 

 albido ante quartam partem exserto. Pemora anteriora spina apicali in margine externo instructa. 

 Yar. a. Macula nigra femorum anteriorum incisuram unguicularem baud transgrediens. — 6. vel illam trans- 

 grediens. — c. Elytra et pronotum maeulis 2 fulvidis vel f usco-cinctis, illas foliarum arbustorum imitantibus, 

 notata. — d. In individuis decoloratis, vel per liquorem adulteratis elytra nonnunquam nigro-punctulata.
