spot in front and two punctiform spots on the vertex. Prothorax 

 black, less shining, with two yellow spots at the front-margin, 

 below these two other ones before the base and three small spots 

 along the sides. Elytra black w^ith a dark bluish hue, shining; 

 each elytron ornated with the following yellow markings, viz. 

 three irregular small spots at the base, an other small one below 

 the shoulder, a very large transverse spot before the middle, below 

 the middle an irregular stripe close to the outer mai'gin and not 

 reaching the apex , and two small spots near the suture. Underside 

 dark aeneous green , very shining ; the breast with six yellow spots 

 in the middle and three on each side; all the abdominal segments 

 with a yellow blotch laterally , these blotches becoming gradually 

 smaller towards the apex. Legs red with a bronzy tinge. 



Head large , swollen , closely punctured , more finely on the 

 vertex, between the eyes a short glabrous line. Prothorax strongly 

 and coarsely punctured, towards the sides slightly rugose, the 

 median lobe with a small impression; slightly convex, the sides 

 rounded and somewhat narrowed towards the top. Elytra striated, 

 the striae composed of transversely impressed large shallow oblong 

 punctures, the interstices plain , sparingly punctured , more strongly 

 along the sides; rather parallel-sided, strongly narrowed behind 

 the middle, the apices slightly diverging, each of them ending in 

 a strong tooth. Beneath coarsely but minutely punctured, the 

 median portion of the breast with a few scattered pum tures only; 

 clothed, legs included, with a silvery pubescence, cliiefly along 

 the sides; prosternum somewhat concave. 



Variability. The pattern being already diflerent on both tlie 

 elytra of the single specimen, I have at my disposal, we may 

 conclude a great variability of the yellow markings ; the basal and 

 apical spots have a tendency to flow together.
