Uppersm'face brightly shining purple-brown , the thorax generally 

 greenish on the disc, underneath and legs of a more brilliant 

 coppery color. Each of the elytra ornated with eight irregular 

 yellow spots, viz. a row of five spots close to the suture, gradually 

 diminishing in size towards the apex, the flrst at the base, the 

 second before the middle , the third below the middle , the fourth 

 about midway between the foregoing and the apex, the fifth just 

 before the suturai spine, and a row of three spots at the outer 

 margin, placed opposite to the three intervals between the first 

 four suturai spots, the subhumeral spot emitting a branch to 

 the base. 



Head rugosely punctured, with an elevated longitudinal line in 

 front ; hairy. Prothorax short and convex , sides strongly rounded 

 and narrowed towards the top, indistinctly margined along the 

 front and the sides; very deeply and confluently punctured on the 

 disc, strongly rugose at the sides; hairy. Elytra suddenly narrowed 

 below the middle , apices strongly diverging , the suturai and 

 marginal spines strong and acute , the humeral fold broadly rounded ; 

 subcostate, the costae only distinct near the apex, according to 

 the interstices , which become the more and more convex towards 

 the base, each of the interstices with a row of distant shallow 

 punctures. Beneath very closely punctate, the punctuation finest 

 on the abdomen; clothed with a silvery pubescence. 



Variability. The small apical spots are as often absent as
