addition to its much greater size, it may be at once known by 

 the absence of the short perpendicular grooves present at the 

 base of the thorax in Podagrica ; it presents also an abundance of 

 other distinctive characters. 



Simcethea Laportei, 



S. elongata, parallela, subcylindrica, nitida ; ore, pectore femoribusque 

 piceis ; tibiis tarsisque fusco-fulvis ; antennis flavis, apice paullo 

 infuscatis ; thorace profunde sed remote punctato ; scutello rufo- 

 piceo ; elytris sat profunde punctato-striatis, rufis, apice nigris. 



Long. 4 Hn. 



Hab. Tringanee. 



Epistome triangular, the lower part of its surface plain, the 

 apical portion obliquely elevated ; face thickened and elevated 

 between the insertions of the antennae, but without forming the 

 usual facial ridge ; encarpse contiguous, large, subquadrate, the 

 lower and inner angle of each produced downwards ; bounding 

 the encarpse above is a deep transverse groove, the upper edge 

 of which is oblique, and gradually lost on the surface of the 

 front j running upwards from this groove are a number of short, 

 nearly perpendicular grooved lines. Thorax rather broader 

 than long ; sides narrowly margined, moderately rounded ; 

 upper surface convex. Scutellum trigonate, its apex obtuse. 

 Elytra scarcely broader than the thorax, parallel, each elytron 

 faintly impressed on the middle of the disk just below the 

 basilar space ; deeply punctured, the punctures somewhat 

 remotely placed in ten or eleven longitudinal rows ; the black 

 apex varies greatly in extent, in some specimens being nearly 

 lost, in others occupying almost a third of the surface. 



Genus Xuthea. 



Corpus elongato-ovatum, convexum. Caput exsertum ; facie tri- 

 angular!, canwa lata, modice elevata; encaipis novi contiguis; antennis 

 gracilibus, filiformibus, corporis longitudine brevioribus, articulo 

 primo paullo curvato, incrassato, secundo illo fere dimidio breviore, 

 a basi ad apicem modice incrassato, caeteris gracilibus, singulatim 

 primo eequalibus ; oculis orbitu circumdatis, prominulis, integris. 

 Thorax transversus, lateribus anguste marginatis, fere parallelis, 

 angulis anticis tuberculo setifero armatis, dorso ante basin trans- 

 versim sulcatus, sulco utrinque fossa perpendiculari brevi ad basin 

 producta terminato. Elytra regulariter punctato-striata. Pedes 

 modice robusti ; coxis anticis distantibus, prosterno fere sequialtis ; 

 femoribus posticis modice incrassatis, subtus leviter sulcatis ; tibiis 

 omnibus apice spina acuta armatis ; tarsorum articulo basali tS am- 

 pliato, posticorum articulo basali duobus sequentibus conjunctim
