cJ . Prasina. Vertex subrotundatus ; ejus pars antica inter antennas trapezina, leviter arcuata, leviter sulcata, 

 apice truncata, subbituberculata, quam primus artieulus antennarum duplo latior, cum scutello faciali 

 angulum obtusum formans. Fastigium frontis illo paulo latius, subincisum, angulis rotundatis. Pronotum 

 disco subplano, ruguloso, ad sulcum typicum transverse depresso, utrinque punctis minimis nigris subtilibus 

 consperso, margine antico sinuato. postico rotundato, leviter parabolico ; cantbi rotundato-acuti. Lobi 

 laterales altiores quam latiores, infra parabolice rotundati, margine antico supra sinuato. Elytra ovato- 

 lanceolata, subcoriacea, dense punctata, reticulato-rugosa ; venis et venulis expressis. Vena humeralis 

 venae discoidali contigua, vena mediastina brevissima, crassa, cum basi venae humeralis fusa. Vena 

 discoidalis prope apicem ramum in margine suturali perductum emittens. Vena media ante medium 

 oriens, furcata, ejus ramus primus cum vena ulnari confluens, ramus secundus ante medium curvatus. 

 Vena ulnaris subrecta, ramos 3 ad marginem suturalem emittens. Discus punctis eburneis raris irregu- 

 lariter conspersus. Campus tympanalis elytri dextri areolam vitream piriformem, per venam rectam basin 

 haud attingentem divisam, praebens. Lobi mesosterni ovati, acuti ; lobi metasterni triangulares. Femora 

 postica subtus in utroque margine spinulosa.

2. Ischyra vepretorum, sp. n. 



cf. Prsecedenti simillima. Vertex apice illo speciei laudatae paulo angustior, subfoveolatus, sulcatus. Primus 

 artieulus antennarum quam in specie laudata latior ; vertex proptor hoc quam ille haud duplo latior. 

 Fastigium frontis cum vertice per sulcum transversum conjuncture. Pronotum longius, postice rotundatus 

 subincisus, arcu obtusiore, in medio minus productus. Elytra semicoriacea, punctata, polygonali- 

 reticulata venisque prominulis, punctis eburneis nullis. Laminae infra-genitalis cesticula styligera haud 

 producta.
