head, pronotum, and scutellum seem to be difierently sculptured, 

 and there is no annulation to the femora. 



Levenna, gen. nov.

 sinuatis, tylo et jugis ceque longis, illo postice elevato, his 

 antice valcle approximatis, ocellis majusmdis, in linea inter 

 marginem posticum ocidorum ducta positis, a linea media 

 capitis qitam ah ocidis saltern duplo et dimidio longius 

 distantibas, buccidis hnmilihus, rectis ; rostro coxas jwsticas 

 attingente, articido secundo dicobus a-jncalihus unitis breviore, 

 tertio quarto longiore, tuberculis antenniferis e sujie^^o 

 distinguendis, extus spimda porrecta armatis ; antennis 

 quadri-articulatis, articido primo apicem capitis paullum 

 superante, secundo longissirno. Pronotu')n medio cajnte 

 parum longius, marginibus lateralibus anticis acutis, leviter 

 explanatis et rejiexis, angidis lateralibus hand 2^'>'omimdis, 

 anguste rottondatis, angulis basalibus latissime rotundatis, 

 margine basalt redo. Scutellum pione mediutn leviter sinuatum. 

 Mesostermmi carinatum. Orificia metasternalia in rugam 

 mediocrem continuata. Hevielytra a2ncem abdominis longe 

 sitperantla, corio ajncem abdoininis subattingente ( cJ ) vel hoc 

 paidlo breviore ( $ ), margine apicali levissime sinuato, angido 

 apicali acuto, membrana venis circiter sex instructa, exterioribus 

 tribus furcatis et p)one medium vena transversa conjunctis. 

 A Ice ajncem abdominis siqyerantes, sed hemelytris p)aidlo breviores. 

 Abdomen heinelytris haudvel vix latius, stobtus utrinque jjrope 

 basin vitta stridulatoria curvata usque ad apicein segmenti 

 teidiijjertracta instructicm, segmentis quinque primis ventralibus 

 in mare medio valde retractis, quam lateribus fere triplo 

 brevioribus,segmento sexto hujus sexusj)ermagno,2>rcecedentihus 

 unitis medio longiore, angidis ajyicalibus hujtts segmenti in 

 mare latissime rotundatis, fere deletis, inargine apicali recto,

 longiusculi, femoj-ibus 2^osticis intus spictdis strididatoriis 

 uniseriatis instructis; tibiis omniMis feinoribus sid)cequilongis, 

 superne sulcatis; tar sis triarticulatis, articido prvno tarsorum 

 posticoriim incrassato. 

 This remarkable genus is to be placed near Commius Stai, but 

 is at once distinguished by the four-jointed antennae, the very 

 long hemelytia, and the enormously developed sixth ventral and 

 genital segments in the male. The considerable length of the 

 hemelytra is probably due to the necessity for preserving the 

 inner parts of the very wide and open male genital segment from 

 injmy.
