 Hub. Mysol. Collected by Mr. Wallace. 



Ovate, very convex, nitidous. Face furnished between the eyes 

 and just above the insertion of the antenna? with two transversely 

 placed, shining tubercles ; jaws, labrum, and antenna? black, the latter 

 rather more than half the length of the body, several of the basal 

 joints fulvous beneath. Thorax convex, smooth, and indistinctly punc- 

 tured on the disk, slightly and singularly excavated on the side just 

 within the lateral border, side margins angustate-rotundate. Elytra 

 shining black, their basal fourth, together with the inflexed limb, 

 fulvous, each elytron impressed with eleven rows of very fine punc- 

 tures, the first row short ; these stria?, however, are discovered with 

 difficulty, owing to the nearly equally well-marked punctation of the 

 perfectly plane interspaces ; near the outer margin, just below the 

 humeral callus, is a shallow smooth fovea. Tibia? unarmed. 



Podontia vittata. 



P. oblonga, valde convexa, castanea, nitida, abdominis basi pectoreque 

 obscuris, antennis (basi exceptis) nigris ; elytris punctato-striatis, mar- 

 gine exteriore, vitta subsuturali (apice cum margine ipso confluente) 

 vittaque angustiore discoidali, ante apicem abbreviata, flavis, limbo 

 infiexo flavo, nigro tessellato ; capite thoraceque fidvis, hoc convexo, 

 minute punctato, utrinque unifoveolato. — Long. 3| lin. 



Hah. Port Natal. 



Oblong, very convex. Head very minutely punctured, face impressed 

 on either side by a deep bisinuate groove, which, commencing just 

 within the insertion of the antenna?, rims obliquely upwards to the 

 upper margin of the eye. Thorax smooth, convex, impressed on either 

 side near the lateral margin with a small fovea, surface minutely punc- 

 tured ; on either side the disk in front are three longitudinally placed 

 deep punctures. Elytra each impressed with eleven rows of deep 

 punctures, the first row very short, interspaces on the outer disk con- 

 vex, those near the suture nearly plane. 



Genus Xenidea. (Details, Plate XXI. fig. 4.) 



Corpus oblongo-ovatum, valde convexum. Caput exsertum ; facie per- 

 pendiculari, longitudinaliter carinata, utrinque supra antennas profunde 

 canaliculata ; antennis gracilibus, fere filiformibus, corpore brevioribus, 

 articulo primo incrassato, secundo illo breviore, paullo incrassato, obo- 

 vato, tertio secundo fere duplo longiore, ca?teris tertio singulatini fere 

 eequalibus ; epistoma elevatum, antice integTum. Thorax transversus, 

 lateribus anguste marginatis, basi biimpressus. ScuteUum trigonatum, 

 apice rotundato. Elytra thorace latiora, apice rotundata, fortiter puncta- 

 tostriata. Pedes .- tibiis intermediis inermibus ; tibiis posticis dorso canali- 

 culars, lateribus ante apicem obsolete sinuatis, ad apicem pectinatis,
