convex, transversely excavated below the basilar space, the hu-

 convex. 



Genus Mouhotia, n. gen. 



Corpus breviter ovatum, valde convexum, supra glabrum. Caput in 

 tlioracem penitus iramersum, perpendiculare ; ocwZis anguste ovalibus, 

 intua siiiuatis, vix prominulis \ clypeo a facie distincte separate, antice 

 concavo-eraargiriato ; antennis quam corporis dimidium longioribus, arti- 

 culis basalibus qiiatuor cylindricis^ cseteris compressis, leviter dilatatis. 

 Thorax transversus, lateribus marginatis, a basi ad apieem convergen- 

 tibus. Scutellum semiovatum. Elytra thorace multo latiora, sub- 

 quadrato-ovata, valde convexa, regulariter punctate -striata, humeris 

 prominentibus. Pedes robusti ; femoribus, prtesertim anticis, incras- 

 satis;, anticis et posticis spina brevi subtus armatis, intermediis mu- 

 ticis ; tibiis posticis quatuor extus ante apieem emarginatis ; ungui- 

 culis acute appendiculatis. Prosternum transversura, subquadratum, 

 apice obtuse truncatum ; episterni antico angulo antero-interno libero, 

 margine antico convexo. Mesosternum breve, transversum. 



Type MouJiotia femorata. 



The transverse prosternum, the appendiculated claws, and the 

 emargination of the four hinder tibia?, combined with the general 

 form, will at once distinguish this genus from Ttjpo^liorus and its 

 allies.

 bosa, nitida ; capite, thorace pedibusque nigris ; pectore piceo ; labro, 

 pleuris, abdomine elytrisqvie rufis ; bis infra basin vix transversim de-
