a little longer in proportion to its basal width, the median dorsal 

 area less widened behind and less deeply impressed near the apex.

 and with indications of an obtuse central ridge. Elytra with the

Colour black, with metallic green scaling above and below ; the 

 prothorax with a broad well-detined dark central stripe, and a 

 narrow abbreviated lateral dark stripe on each side ; the elytra 

 with a sharply defined dark stripe on intervals 2 and 4 from near 

 the base to behind the middle, that on 2 continuing a little 

 further backwards, the suture «ith golden brown scaling through- 

 out, interval 3 with golden green scaling on the disk. 



Head with the eyes quite lateral and rather prominent, the 

 forehead much broader than the space between the scrobes. 

 Rostrum about as long as the head, broader than long, the sides 

 rather narrowed from the base to the middle and slightly dilated 

 at the apex, the apical emargination shallow, the base of the 

 epistome being broadly rounded ; the upper surface shallowly 

 impressed and with a faint central carina, the external carinse 

 fairly distinct. Antennce flavesceut, the scape setose ; the funicle 

 with the" two basal joints equal, and 3 slightly longer than 4. 

 Prothorax about as long as broad, the sides slightly rounded, 

 broadest at the middle, shallowly constricted before and behind, 

 the apex obliquely truncate, not narroA^er than the base, which is 

 bisinuate and with the angles acute ; the upper surface almost 

 plane and bounded laterally by an indistinct undulated costa, 

 with a rounded impression on each side behind the middle, the 

 two being united by a shallow curved transverse impression, the 

 punctation not visible through the scaling, the setae very short 

 but erect. Elytra separately rounded at the base, the shoulders 

 prominent but rather sloping, the sides subparallel, the striae 

 narrow but distinctly punctate, the setae short, iiu-onspicuous and
