Long, -ii lin. 



C. broadly elongate, slightly dilated behind, subdepressed, pale rufo- 

 fulvous ; elytra with their posterior angles produced almost directly 

 outwards into a flattened, slightly curved, acute black spine ; their 

 apex obliquely truncate ; bright metallic green, stained with fus- 

 cous behind, each with eight pale yellowish-white spots. Head 

 smooth, produced in front into a short acute tooth ; antennae 

 elongate, moderately robast, filiform, joints cylindrical, second 

 one-half longer than the fii'st, four terminal joints short. Thorax 

 transverse ; sides narrowly margined, notched at the extreme base, 

 rounded and slightly produced behind the middle, narrowed and 

 sinuate in front, anterior angles produced into a stout obtuse 

 tooth, posterior anned with a minute tooth ; above convex, trans- 

 versely depressed near the middle of the base, whole sui-face 

 covered with large round pimctures. Scutellum smooth, impunc- 

 tate. El}i;ra broader than the thorax, slightly dilated towards 

 the posterior angles, the latter produced almost directly outwards 

 into a stout flattened spine, the apex of which is curved slightly 

 backwards ; sides margined, subsinuate below the shoulders ; apex 

 obtusely rounded, apical margin (Tab. IX. fig. 15) obliquely tinin- 

 cate, entire ; above flattened along the suture, convex on the 

 sides ; shoulders prominent, laterally produced, theii' apex sub- 

 acute ; siuface deeply and regularly punctate-striate, all the in- 

 terstices on the sides, and the alternate ones on the inner disc, 

 indistinctly elevated ; bright metallic green, stained with fuscous, 

 less metallic towards their apex, posterior spine black ; each ely- 

 tron with eight yellowish- white spots : viz. one basal ; the second 

 below the scutelliun, common ; the third placed on the outer sur- 

 face of the shoulder, confluent mth the outer border ; three others 

 smaller, and placed obliquely from the middle of the suture to the 

 outer margin, just above the upper edge of the posterior spine;
