Obs. — The entire insect has a silken sheeny appearance, the 

 colour changing remarkably according to the light the insect is 

 held in. There are some specimens before me in which the elytra 

 are coppery-golden and the tliorax slightly darker, its anterior 

 margin and angles alone golden-green.

 Several examples. 



Chrysobothris succedanea, E. S. Capite viridi-aeneo, cupreo-mi- 

 cante, punctata, fronte transverse carinata. Thorace purpureo-fusco, 

 transverse rugoso et punctato, lateribus cupreis. Elytris purpureo- 

 fuscis ereberrime punctatis, tribus foveis aureis utrinque notatis ; su- 

 tura prope apicem viridi. Subtus aureo-viridis, lateribus tibiisque 

 roseo-cupreis. 



Head bronzy, with green and coppery reflections, transversely rugose, 

 and with a strong transverse keel. Thorax purplish brown, with the 

 sides coppery, slightly wider behind than in front ; sides nearly 

 straight ; posterior angles largely rounded ; base deeply bisinuate ; 

 surface deeply punctured and transversely rugose ; on each side, par- 

 allel to and very near the margin, is a well-marked carina. Elytra 

 brown, with a purplish tinge, deeply and very closely punctured, each 

 with three golden foveae — one at the base (a small one), one just above, 

 and the other just below the middle. Besides these, there is a little 

 green spot just behind each shoulder, and a streak of green on the 

 suture just above the apex; sides denticulate posteriorly. From the 

 apex a carina runs up parallel to the suture till it reaches the middle 

 fovea; another runs parallel to the side as far as the shoulder. 

 Beneath punctured, golden green, with the sides and tibiae rosy copper- 

 colour.

Head rugosely punctured, golden coppery, impressed between the eyes, 

 and golden pubescent. Thorax golden coppery, clouded on the disk, 

 rugosely punctured ; sides covered with yellow hairs ; posterior angles 

 and base depressed, so as to give the disk a raised appearance ; side 

 margins finely crenulate ; base bisinuate. Elytra finely rugose, cop- 

 pery brown in front, purplish black posteriorly and along the suture ; 

 on each is a small round spot below the base, an irregular narrow
