184 Mr. Curtis' s Descriptions of 



Very glossy, piceous inclining to castaneous : head and thorax greenish-black, 

 the latter convex, cupreous on the disc, with a deep channel down the 

 middle, the sides with a very narrow margin : elytra cupreous, the sides 

 with green lines, twice as long as the thorax and perfectly convex, with 

 shallow interrupted striae, vanishing on the sides and apex, costa with a 

 narrow margin, a foveolet at the base and 3 towards the apex ; trophi, an- 

 tennce and legs ferruginous ; thighs castaneous. 



This species I have named after Lieut. T. Graves, to whom I am indebted 

 for a pair : several were taken at Port St. Elena.
