(Subfam. Stizopides.) 



Genus Eremonomus (nov. gen.). 



Corpus sat parvum, breviter rotundato-ovale, convexura : fronte ad 

 latera leviter elevata et ibidem valde exstante, ad apicem fere integra ; 

 oculis antice profunde emarginatis : prothorace transverse, antice 

 late sed leviter emarginato, postice truncate (vix sinuato), angulis 

 posticis baud productis, ad latera valde rotundato et anguste expla- 

 nato : scuiello sat magno, triangulari : sternis abdomineqne fere ut in 

 Halonomo, sed lobo prosternali paulo minus horizontali (i. e. postice 

 paulo magis deflexo, ibidem nee acute nee suberecto), necnen excava- 

 tione triangulari mesosternali minus argute determinata et ad apicem 

 ipsum truncata (baud acuta) : elytris Uberis : alis sat magnis, tenui- 

 bus. Antennce capitis pretheracisque longitudine, basi graciles, 

 apicem versus leviter incrassatse, articulo 1™° sat rebuste subcurvato, 

 2**" paulo breviere vix graciliore subclavato, 3*'" primi lengitudine, 

 4*° secundi longitudine, 5*" 6*oque brevioribus sequalibus, reliquis 

 quinque latitudine gradatim crescentibus (ultimo subrotundate). 

 Labrum submembranaceum, transverse-sub quadratum, ad latera et 

 prsesertim ad angules anticos rotundatum, apice leviter emarginatum. 

 Mandibulce validae, cernese, triangulares, una valde incurva apice 

 obtuse bifida necnen infra apicem profunde fissa coriacea, altera vix 

 incurva apice integra necnen versus basin fissa coriacea. Maxilla bi- 

 lebse : lobo externo pubescente, setose ; interno ad apicem biuncinato, 

 intus pubescenti-setoso. Palpos baud observavi. Mentum trans- 

 verso-quadratum, ad latera rectum, antice latissime sed baud pro- 

 funde emarginatum. Ligula ad basin tegumento submembranaceo 

 cennexivo cum mento cenjuncta, cornea, rebusta, subcerdata (i. e. 

 basin versus facile attenuata, ad latera et angules anticos rotundata 

 necnen ad apicem vix emarginata), anguhs anticis fertiter setoso- 

 ciliatis. Pedes robusti : femoribus sat crassis, muticis : tibiis fertiter 

 setulosis ; anticis late ddlatatis compressis, per marginem externum 

 irregulariter sed profunde ereso-subdentatis ac breviter setoso-spinu-^ 

 lesis, in dentes duos vel tres obtuses valde irregulares plus minus 

 distinctes erosis: tarsis heteromeris, posterioribus (sed prsesertina 

 posticis) articulo 1""" longiusculo. 



Obs. Genus tibiis anticis dilatatis extus profunde sed irregulariter 

 subdentato-eresis, superficie ubique granulate-asperatis (vix punctu- 

 latis), striis elytrerum obscure nigrescentibus sed baud impressis 

 limboque (ut in Phaleriis) ciliate, necnen structura ligulse rebustis- 

 simse subcornese cordatee sat anemalum distinctum, et cum Styzo- 

 pidibus secundum clariss. Lacordaire recte ponendum.
