black ; the sides sparsely punctate, glabrous and glossy ; the front 

 minutely, and the vertex more strongly, punctulate, both faintlv 

 pubescent ; mandibles vary in the male 

 according to the size and development of 

 the individual in large males they are 

 rather long and horizontal, furnished 

 each with a strong dorsal ridge and a 

 tooth near the base ; in smaller males 

 obliquely inclined as in the female, with 

 the dorsal tooth small or even entirely 

 absent. Antennae longer than the 

 body by the last five joints in the d 

 and the last four in the ? 5 pale blue, 

 with the first two joints entirely and 

 the rest at the apex black ; third to 

 sixth strongly, and some of the suc- 

 ceeding joints feebly, tufted with black 

 hairs at the apex. Froth orax rounded 

 at the sides, slightly narrowed towards 

 the base ; the disc with a large black 

 spot that extends from the middle to the 

 front margin and spreads out in front, also a small round black 

 spot on each side. Scutellum blue. Elytra marked each with 

 four large transverse spots or bands one at the base, the second 

 at one-fourth from base, the third just behind the middle, and the 

 fourth a little before the apex. Body beneath for the most part 

 pale blue, with the raesothorax almost wholly black. Legs black ; 

 the femora, which are gradually thickened and subfusiform towards 

 the apex, with a pale blue ring or spot on the thickest part ; hind 

 tibiae dilated and fringed with hairs at the apex ; middle and hind
