marked with six pale fulvous spots. Head angled in front between 

 the eyes, impressed above with a deep fovea ; antennae slender, 

 their apex subincrassate, joints eylindiical, second more than 

 tA\aec as long as the first, half as long again as the third, four 

 apical joints black ; eyes pitchy black. Thorax rather broader at 

 the base than long, naiTowcd from its base to the apex, subconic ; 

 sides straight, antenor angles produced, acute ; apical margin 

 straight ; above subconvex, transversely depressed behind the 

 middle, closely and coarsely punctm-ed, the middle portion of the 

 basal margin and an interrupted longitudinal Hne down the 

 centre of the disc, slightly raised, impimctate ; whole surface 

 (especially the smooth raised portions) ^\ith a very faint metaUic 

 reflexion. Scutellum smooth, shining. Elytra broader than the 

 base of the thorax, subparallel, rather broader behind their 

 middle ; sides narrowly margined, margin sHghtly dilated towards 

 the posterior angle, the latter armed with a flattened acute spine, 

 which runs almost directly backwards ; apical margin (Tab. IX. 

 fig. 23) rounded, scarcely dilated, its edge obsoletely dentate near 

 the posterior angles ; above subdepressed, convex on the sides ; 

 shoulders prominent, laterally produced, theii' apex subacute ; 

 surface deeply and regularly punctate-striate, the suture and 

 each alternate interstice subcostate, those on the inner disc more 

 raised than the others ; rufo-fiiscous, with a metallic green re- 

 flexion ; each elytron "with six pale fulvous spots : three on the 

 sutural margin, common ; and three others attached to the outer 

 border, the last of these transverse, subapical, extending from 

 the posterior angle nearly to the suture. Beneath shining rufo- 

 fulvous ; legs less elongate, moderately robust, anterior pair of 

 tibiae armed just before the apex with a short subacute tooth.
