Oxacis) acute, but if the expression be taken in a general sense 
as equal to “ pointed,” it would apply well enough.

This species is unmistakable, by the characters cited in the 
preceding table. In colouring it evidently resembles Copidita 
bipartita, Champ., from which its simple mandibles, no doubt, 
readily separate it. In one specimen there is on the elytra a 
short streak of paler colour from the base on the middle of the 
disc in addition to the pale margin; in another example (an 
immature one, I think) the prothorax has several feeble impres- 
sions.

The testaceous lines on the elytra are one sutural, one mar- 
ginal, and one intermediate between the former two, all narrow, 
sharply defined, and apparently constant ; some examples have
