Genus Metalepta. 



Corpus elongatum. Caput exsertum, modice porrectum ; antennis filiformi- 

 bus, modice robustis, articulo basali curvato, a basi ad apicem incras- 

 sato, secundo primo dimidio breviore, tertio paullo elongato ; mandibulis 

 robustis, apice dentatis ; palpis maxillaribus articulo ultimo conico ; 

 mento brevi; ligula trigona; oculis modice prominulis, subrotimdatis, 

 integris. Thorax transversus. Scutellum transversum, semirotundatum 

 vel obsolete trigonatum. Elytra fmmince abbreviata, apice divaricata. 

 Abdomen fcemince ultra elytra valde extensum. Pedes elongati, ungui- 

 cidis ante apicem dentatis. Prosternum gracile, postice abbreviatum. 

 Metasternum (Plate XL fig. 9) brevissimum. 



Type, Metalepta tubermlata, Baly. 



Although unwilling to found a genus on a single sex (and that 

 the female), I consider, in the present instance, the extremely short 

 metasternum quite sufficient to separate Metalepta from all allied 

 generic forms. 



Metalepta tuberculata. (Plate XI. fig. 9.) 



M. elongata, obscure cuprea, subnitida ; antennis pedibusque piceis, cupreo 

 vix micantibus ; capite thoraceque rugosis, hoc quadrituberculato ; elytris 

 abbreviatis, concavis, apice divaricatis, utrisque extrorsum reflexo-mar- 

 ginatis margine exteriori bisinuatis; scutello late transverso, obtuse 

 rotundato. — Long. 5-6 lin. 



Hab. Peru. 



Head rugose; antennae moderately robust, filiform, six basal joints 

 pale, the five others dark piceous ; thorax nearly twice broader than 

 long, sides rounded, armed at each angle with a smooth prominent 

 round tubercle, upper surface transversely excavated across the middle, 

 the surface rugose-punctate, transversely strigose, middle of the disk 

 impressed at the base with a large shallow fovea; elytra granulose, 

 their surface impressed with numerous shallow circular pits, which are 

 more crowded towards the apex ; legs pale piceous, third joint of tarsi 

 and the claws darker. 



Metalepta De Ganclii. 



31. elongata, obscure cuprea, nitida; abdominis inflati dorso, corporeque 

 subtus, piceis, cupreo vix micantibus ; capite thoraceque rugosis, hoc 

 disco irregulariter excavato, lateribus a basin ad paullo ante medium 

 ampliato-rotundatis, leniter reflexis, hinc ad apicem rotundato-emargi- 

 natis, angulis singulis in dentem brevem subacutum productis ; elytris 

 abbreviatis, concavis, reflexo-marginatis, rugosis, apice divaricatis, extus 

 flexuosis; scutello lato, obsolete trigonato, lateribus rotundato, apice 

 obtuso. — Long. 5J lin.
