290 Mr. J. S. Baly's descriptions of new genera 



sinuate, metallic green ; antennae slender, filiform, the 

 two lower joints obscure fulvous, the rest black ; labrum 

 metallic green. Thorax more than three times as bi'oad 

 as long ; anterior margin deeply concave ; sides straight 

 and slightly converging from the base to behind the 

 middle, thence obliquelj- converging to the apex, all the 

 angles acute ; basal margin oblique and slightly bisinuate 

 on either side, the medial lobe broadly and obtusely rounded ; 

 disk very minutely granulose, sparingly impressed with 

 minute punctiu'es. Scutellum subtrigonate, its sides 

 rounded, its apex acute. Elytra scarcely broader than 

 the thorax, very convex, obtusely gibbose before the 

 middle, slightly excavated near the base close to the 

 scutellum, finely but distinctly punctured, the punctures 

 arranged in ill-defined longitudinal rows ; interspaces 

 plane ; inflexed limb horizontal, plane.

Eotundatus, valde convexus, niger, nitidus, antennis 

 piceis, basi obscure fulvis; pedibus piceis, tarsis piceo- 

 fulvis ; thorace subcrebre punctato ; elytris sat fortiter punc- 

 tato-striatis, interstitiis ad latera et ad apicem convexis ; 

 utrisque plaga magna subrotundata, ante medium posita, 

 ornatis.

Head piceo-reneous, coarsely punctured ; clypeus much 

 longer than broad, wedge-shaped, subpentangular, its 

 apical angle obsolete, its anterior margin bidentate ; an- 

 tennse more than two-thirds the length of the body, 

 filiform^ the four lower joints obscure fulvous, the rest 

 piceous ; labrum fulvous, its anterior border deeply emar- 

 ginate ; jaws nigro-piceous. Thorax nearly three times 

 as broad as long ; sides obliquely rounded and converging 

 from base to apex, very oblique before their middle, all 

 the angles acute ; basal margin oblique and obsoletely 

 bisinuate on either side; disk deeply punctured. Scu- 

 tellum semirotundate, its apex acute. Elytra rather 

 broader than the thorax, attenuated towards the apex ; 

 convex, rather strongly punctate-striate, the interspaces 

 plane, convex at the apex and near the lateral margin ; 

 each elytron with a large subrotundate rufous patch, 

 extending from just below the basal margin nearly to the
