BUPRESTID GENUS ASTRAEUS. 93 



very shining, underneath aeneous-green with the legs violaceous, 

 shining. Each elytron with a curved yellow hand before the middle 

 touching the outer margin below the shoulder but not reaching the 

 suture, its concavity turned towards the base, and an other some- 

 what angular band below the middle, also touching the outer 

 margin only. 



Head regularly punctured, with an elevated line in front. Pro- 

 thorax very short and convex, the sides strongly rounded and 

 narrowed towards the top, the posterior angles much projecting, 

 narrowly margined along the front and the sides; distinctly but 

 sparsely punctured on the disc, somewhat more densely at the 

 sides. Elytra strongly narrowed below the middle , apices strongly 

 diverging, the suturai and lateral spines very long and acute, the 

 humeral fold angularly not acutely produced, provided with sharp 

 ridges, the interstices plain, faintly punctured and transversely 

 wrinkled. Beneath coarsely punctured , more finely on the ab- 

 domen, the prosternum rather rugose; clothed with a delicate 

 silvery pubescence. 



This species is closely allied to the pi'eceding, but besides the 

 great difference in size and color, it may be easily distinguished by 

 the elytral costae , which are distinct over the whole of their length. 



Two specimens in coll. Oberthiir.
