vix ante apicem posita, ad marginem adfixa, maculaque parva discoi-

Hah. Muzo ; Medellin ; Eastern Colombia ( ^JTm^Zer). 



Head rather longer than broad, triangular ; encarpae thickened, 

 contiguous ; carina moderately elevated, linear ; labrum and 

 palpi nigro-piceous. Antennae filiform, the basal joint beneath 

 piceous ; the second joint sliort, the third twice as long, equal 

 in length to the fourth. Thorax more than one half as broad 

 again as long ; sides rather broadly margined, straight and 

 slightly diverging from the base to beyond the middle, thence 

 obliquely converging to the apex ; surface shining, impunctate, 

 middle disk with a broad transverse excavation, which is rather 

 more deej)ly impressed on either side. Elytra narrowly oblong- 

 ovate, very slightly dilated posteriorly, convex, flattened along 

 the suture ; each elytron with a deeply impressed, distinct 

 longitudinal groove, which commences below the humeral callus 

 and runs downwards to some little distance below the middle of 

 the disk ; this groove, which curves slightly inwards, is bounded 

 on its outer edge by a distinctly elevated costa ; the surface of 

 the groove, together with the space between it and the outer 

 margin, strongly jDunctured ; rest of the disk very minutely punc- 

 tured; the subapical flavous fascia is broad and placed immediately 

 before the apex of the elytra ; it is sometimes abbreviated at the 

 extreme sutural margin.

 blue or green, the outer limb, together with a medial fascia, 

 flavous ; each elytron in the male with a slightly curved 

 subapical tubercle placed near the suture.
