Elongate, feebly triangular, broadly rounded in front, more ac- 

 cuminate posteriorly, and feebly flattened above (nearly straight be- 

 neath and moderately arcuate above when viewed in profile) ; pice- 

 ous, with a slight aeneous tinge; pronotum with a lateral yellow 

 longitudinal band, not quite touching the lateral margin, and some- 

 times abbreviated anteriorly; elytra without i^cal markings, but 

 with a yellow marginal band extending from the humeri to a little 

 behind the middle, and becoming slightly wider posteriorly, and 

 with two transverse reddish or yellowish fasciae near the apex, the 

 two fasciae sometimes connected, forming a broad band, and enclos- 

 ing one or more small dark spots ; beneath more shining than above. 



Head nearly flat, with a broad, moderately deep, oval depression 

 on the front, and forming two more or less distinct elevations; 

 occiput with a longitudinal carina extending to the frontal depres- 

 sion; surface densely and coarsely punctate, the punctures rather 

 deep, irregular, and nearly confluent, the sides forming a network of 

 polygonal areas, bottom of punctures smooth and from the center 

 of which arises a long erect inconspicuous hair; epistoma broadly and 

 deeply triangularly emarginate in front, with the lateral angles 

 broadly rounded; antennae serrate from the fifth joint. Pronotum 

 strongly transverse and moderately convex, two and one-half times 

 as wide as long, distinctly narrower in front than behind, widest at 

 basal sixth, with a large, rather deep median depression, which is 

 broader posteriorly, and with a small very deep depression on each 

 side near the base, about midway between the middle and lateral 

 margin ; sides obliquely expanded from apical angles to basal sixth, 

 where they are arcuately rounded, the margins rather broadly flat- 

 tened and visible from above; anterior margin deeply arcuately 

 emarginate, with a broadly rounded lobe at the middle; base trans- 

 versely truncate, the p€>sterior angles obtusely rounded; surface 

 densely, coarsely and regularly punctate, the punctures well sepa- 

 rated on the disk, but becoming denser and more confluent toward
