dente medio bifido et nialis rotundatis. Ligula curta, trun- 

 cata, leviter emargiuata^ antice quam postice latior^ carinata. 

 Paraglossse nullfe. Antennae breves nioniliformes, articu- 

 lis apicalibus velutinis compressis et dilatatis, cum spatio 

 sat lato Isevi et nitido singulis relicto et supra et subtus. 

 Prothorax subquadratus, anguste marginatus, capite multo 

 latior, antice quam postice parum angustior, linea tenui 

 longitudinali media ct lineis duabus posticis longitudinaliter 

 impressus, angulis anticis parum acutis, posticis fere rectis. 

 Prosternum sat prominens et paulo projiciens, Scutellum 

 mediocre. Elytra prothoracis fere latitudine, brevia^ sat con- 

 vexa et sat fortiter marginata, striata, apice emarginata baud 

 truncata. Pedes mediocres. Tibiae anticse dilatatse, intus 

 emarginatse, subtus excavatse. Tarsi breves transversi et mo- 

 niliformes^ antici breviores ; in foemina et supra et subtus nitidi 

 et politi, sine setis vel squamis, ciliis ad marginem anteriorem 

 singulorum adstrictis exceptis ; in mari antici squamis setis- 

 que instructi, ceteris ut in foemina. Unguiculi simplices. 

 Corpus baud elongatum, parum convexum. Abdomen seg- 

 mentis quinque, quorum primum et secundum conglutinata 

 sunt. 



Tbis genus is nearly allied to the preceding^ but it differs in 

 its shorter, more compact, and convex shape, somewhat different 

 form of the thorax, and in its raentum having a bifid tooth in 

 the middle instead of a single tooth ; in the last joint of the labial 

 palpi being slender elongate-ovate instead of large, swollen and 

 securiform, and in the underside of the anterior tarsi in the 

 male being furnished with closely applied squamulse instead of 

 long bristles.
