(^9. Integument black, clothed with dark grey or blacl-iish 

 scaling (often abraded), the elytra with a broad stripe of silvery 

 green scaling Ijang in the hollow between intervals 3 and 7 in the 

 basal half and between ints. 3 and 6 in the apical, the two portions 

 being broadly interrupted ; the prothorax "vvith a few metallic green 

 scales in the middle of the base, and an irregular narrow lateral 

 strijje of similar scales, which is continued on the elytra between 

 striae 8 and 9 in the ^, but not in the 5; the sides of the stenuim 

 and the two basal ventritos more or less densely clothed with metallic 

 green, which sometimes extends to the lower surface of the head. 



Head fairly closely and shallowly punctate, not constricted behind 

 the eyes, the forehead slightly flattened transverse!}^ and with a 

 small median fovea. Rostrum a little longer than its basal width, 

 gradually widened from base to apex, the sides straight ; the doisum 

 with a broad deep triangular median dejoression and a small oblique 

 impression on each side ; the interantennal area broadly impressed, the 

 epistomal bristles longer and more dense than usual. Anteniiae v/itb the 

 scape gradually widening from base to apex, exceeding the hind margin 

 of the eye, and clothed with dark grey scales and subrccumbent pale 

 setae; the funicle with bluish green hair-like scales, the joints in 

 order of length: (1, 2), 3, 4, (5, 6, 7), the apical joints nearly as 

 broad as long. Prothorax as long as the basal width, the sides gently

 constriction ; the gular margin not or very feebly sinuate ; the 

 dorsum with a deep conical median depression, divided across the 

 middle by a transverse ridge, the latera.1 areas transversely rugose 

 and shalloAvly impressed, the intervening ridges broad, smooth 

 and with fine shallow punctation; no apparent setae. Bcutclhim 

 small, trapezoidal, broadest behind, squamose. Eh/tra elongate, 

 the shoulders sloping and obtuse, the sides subparallel from there to 

 beyond the middle, the apices each produced into a short obtuse 

 process; the dorsal outline convex, the posterior declivity with a 

 slope of 50°; the striae regular, and with quadrate closely set 

 punctures; interval 3 markedly costate throughout, 6 slightly
