prothorax longditndine fere dimidio latior, antice a medio sub-dia- 

 gonaliter attenuatus, pone medium leviter sinuatus, parum convexus, 

 crebre punctatus, in medio linea media depressa longitudinal! basi 

 apiceque evanescente ; scutellum punctatum ; elytra basi prothorace 

 perparum latiora et triplo longiora, ovato-ampliata, medio prothorace 

 tertio latiora, versus apicem acuminata, a basi ultra medium parum 

 convexa, deinde longe deflexa, margins laterali acuta, apice deplanata, 

 vage prope suturam striis linearibus quatuor prtedita, superficie tota 

 coriacea, ad latera granose rugosa ; epipleura sub-levia ; pedes 

 sub-validi, modice elongati, rugoso-punctati, vix pubescentes ; 

 corpus subtus punctulatum, abdomine strigillato. Long. 16 mm. ; 

 lat. 10 mm. 



It is at once distinguishable from the other species by the more 

 elongate shape of the elytra, and the less abrupt incline of the 

 posterior part.

UMSLATUS, nov. gen. 



Mentum trapeziforme, palpi maxillares sub-validi, articulo ultimo 

 securifornii ; labrum longitudine duplo latior, apice haud emar- 

 ginatum ; oculi elongati, sub-reniformes, antice profunde emarginati ; 

 caput latitudine longius ; antennas graciles, longae, fere medium 

 elytrorum attingentes, articulis elongatis, quatuor ultimis praecedentis 

 vix brevioribus; prothorax rotundatus ; scutellum latum, triangulare; 

 elytra ovata, apice acuminata, margine laterali acuta ; epipleura 

 angustissima ; pedes graciles, longi, femoribus posticis abdomine 

 tertio longioribus, anticis ante apicem subtus dente valido armatis ; 

 prosternum breve, processu triangulari apice emarginato coxas 

 haud excedente, mesosternum haud incisum. 



The antennae are as slender as in some species of the gen. 

 Acanthomera, and the joints are similar, but the prosternal process 

 does not project at all between the coxae, the basal joints of the 

 anterior tarsi are not dilated, and the hind legs, especially the 

 femora, are much longer than the abdomen. 



UMSLATUS AGILIS.

 pedibusque, femoribus apice exceptis, sub-rufescentibus ; caput 

 elongatum, antice paullum attenuatum, ante antennas transversim 

 impressum ; oculi clistincti, superne ampliati ; antennae graciles
