B. chrysis, Fab.; Oliv., lb., II, 8, VI, 52, 6. Differing from

 without whitish spots. 



B. vittata, Fab.; Oliv., lb. Ill, 17. Nearly an inch and a half 

 long; narroAver and more elongated than the preceding species; 

 depressed; bluish-greenj four elevated lines, and a cupreous and 

 golden band on each elytron, the end of which is bidentate. 

 East Indies. 



B. ocellata. Fab.; Oliv., lb. I, 3. Almost similar to the pre- 

 ceding in form and size; a large, yellow, phosphoric spot be- 

 tween two golden ones, on each elytron, which is tridentate at 

 the extremity. 

 The others are furnished with a scutel. 



B. gigas, L.; Oliv., lb. I, 1. Two inches long; thorax cu- 

 preous, mixed with brilliant green, and two large smooth spots 

 of burnished steel; elytra tridentate at the extremity, cupreous 

 in the middle, bronze-green on the margin, with impressed 

 puncta, and elevated lines and rugae. Cayenne. 



B. affinis^ Fab.; B. chry so stigma^ Oliv.,' lb., VI, 54. Bronze 

 above, brilliant cupreous beneath; elytra serrated at the point, 

 with three elevated longitudinal lines, and two golden impress-

B. viridis, L. ; Oliv., lb., XI, 127. About two lines and a

Fabricius has separated from the true Buprestides those in which 



the body is shorter, wider in proportion, and almost triangular; the 



front concave, thorax transversal and lobate posteriorly; where the 



tarsi are very short and the pellets broad. The five last joints only 



of the antennae here form the teeth of the saw, the preceding ones, 



with the exception of the two first, being small, almost granose, or 



obconical; the two first are much stouter. These species compose 



the genus Trachys(2), one of which is 



B. minuta, L. ; Oliv., lb., II, 14. Black underneath; cupre- 

 ous-brown above; middle of the front indented; posterior margin
