94 MONOGBAPHICAL ESSAY ON THE 



Shining, head and thorax bronzy-black, the latter with faint 

 purplish tinges; elytra bluish-black with a violaceous reflection, 

 undersurface and legs dark aeneous , more or less mixed with 

 purplish-brown. Each of the elytra with a yellow spot at the 

 base, a curved yellow band before the middle, touching the outer 

 margin below the shoulder and stopping close to the suture, its 

 concavity turned towards the base, a smaller band, which also 

 touches the outer margin only, below the middle, and a small spot 

 before the apex. 



Head coarsely punctured, hairy. Prothorax short and convex, 

 strongly rounded at the sides and narrowed towards the top, 

 slightly margined along the front and the sides; thickly punctured , 

 coarsest laterally , with a faint indication of an impressed median 

 line, hairy. Elytra strongly narrowed below the middle, apices 

 much diverging, suturai and marginal spines strong and acute, 

 the humeral fold rather large , slightly angularly produced ; costate , 

 the interstices plain , each of them with a row of large deeply 

 impressed punctures , moreover slightly wrinkled in a transverse 

 direction. Underneath very closely punctured, more finely on the 

 abdomen ; clothed with a soft silvery pubescence. 



Variability. The basal band is often interrupted in the 

 middle. In some specimens the apical spots are wanting and in 

 one example the apical band is also reduced and does not reach 

 the outer margin. 



Number of specimens examined: six, in coll. Oberthür and van 

 de Poll. Dedicated to Dr. F. Baden.
