•wholly or partly, and the sides of the hind coxae orange-red, and 

 the tarsi black. 



This is a small species, rather elongate in form, depressed above 

 and strongly, almost rugosely, punctured. The head is rather 

 parallel-sided, excavated and granulated, with the margins not 

 much elevated and the anterior process bifid, with the points not 

 very divergent. The protliorax and eliitra are coriaceous and 

 strongly punctured, and there are rudimentary costse upon the 

 latter. ' The sides of the prothorax are sinuated and completely 

 margined, the hind angles rather prominent and the base strongly 

 excised before the scutellum, which bears a few fine punctures. 

 The sides of the elytra are rather strongly sinuated behind the 

 shoulders. The jujgidiuni is feebly rugose, the metasternum punc- 

 tured and clothed with long yellow hairs, except in the middle, 

 which, with the abdomen, is smooth and shining. The sternal 

 process is extremely slender and curved. 



6 . The posterior cephalic process is slender and acutely 

 pointed, and the prothorax tapers towards the front. The 

 abdomen is not channelled beneath. 



$ . The posterior cephalic process is T-shaped and slender, and 

 the prothorax broad.

In the typical green form the hind femora and the greater part 

 of the front and middle femora are metallic green, but in the blue 

 variety all the femora, as well as the tibiae, are orange-coloured. 



A female of Ileterorrhina tibialis, Westw., was associated by 

 Adam White with a male of this species in the belief that they 

 were the two sexes of the same insect, and it is that insect which 

 is represented in fig. 2 of the Plate quoted above. 



82. Trigonophorus scintillans, sp. n. 



Bright shining green or golden-green above and beneath, with 

 the tibiae and the sides of the hind coxae bright yellow, the femora 

 slightly suffused with metallic green and the tarsi black. 



The body is depressed and rather broad. The ch/peus is 

 strongly granulated in front and the anterior horn entire. The 

 pronotum is coriaceous and strongly punctured at the sides, the 

 scutellum bears a very few punctures, and the elytra are well 

 punctured. The pygidium is shining, but granulose and slightly 

 setose, the metasternum shining and strongly but not closely punc- 

 tured at the sides, and the abdomen almost smooth. The sternal 

 process is long, narrow, and directed a little downwards. 



S . The anterior cephalic process is long and gently dilated and 

 the posterior pi'ocess acute and moderately long. 



2 . The anterior cephalic process is short and rapidly dilated
