Hah. Malay peninsula. 



Vertex smooth, impunctate ; cljpeus transverse- quadrate, 

 subrugose-punctate, plane, the carina nearly obsolete ; antennae 

 longer than the body, the third joint twice the length of the 

 second, two thirds as long as the fourth. Thorax more than 

 three times as broad as long ,* sides straight and obliquely 

 converging from base to apex, the anterior angles obliquely 

 truncate, the hinder ones slightly produced, acute ; disk 

 smooth and shining, impunctate, transversely depressed across 

 the disk, the depression not extending to the lateral border, 

 but impressed at either end by a shallow fovea. Elytra 

 oblong, broadly rounded at the apex, strongly and closely 

 punctured, bright metallic green; each elytron before its middle 

 with a curved fulvous fascia, interrupted on the outer disk, 

 but united at the suture to its fellow of the opposite elytron, 

 and forming an acute angle, its apex directed backwards ; 

 close to the suture near its apex is an oblong concolorous spot.

 joint nearly three times the length of the second, about three 

 fourths as long as the fourth. Thorax three times as broad as 

 long ; sides nearly straight and parallel, rounded at the ex- 

 treme apex, the anterior angles thickened, obtuse; disk nearly 

 impunctate, transversely excavated across the middle, the
