insect. The face is black, except a conical slender fulvous line down 
the centre, broadest next the labrum, which has the front also 
fulvous. The mandibles are large, with a moderate sized deflexed 
acute spine in front at the side of the base. The head above has 
a ferruginous streak behind the eyes. The front margin of the 
prothorax, a broader central fascia, and a slender subapical one 
interrupted in the centre, are of a ferruginous colour, as are also 
the two basal fascim, and about nine spots on each elytra occa¬ 
sionally partially confluent, the apical one acutely angulated. The 
metasternum is fulvous, with two green spots at each side, and the 
abdomen is fulvous, with the sides green and centre black.

Although this insect appears at first sight so entirely distinct 
from the preceding species, I must confess it is with doubt that I 
retain it as distinct, for although the prevailing colour is fulvous, 
yet in various parts we see little touches of silvery gi‘een, indicating 
the more ordinary dispositions of that colour. The elytra also, 
when examined, are found to have the black or green markings of 
the preceding species clearly distinguishable, although so thickly 
irrorated with fulvous as at first sight to appear merely^ as indistinct 
cloudings over the elytra. The body beneath is elegantly varied 
with fulvous and silvery green.

The face is black, and both the labrum and base of the man¬ 
dibles, and a triangular patch on the clypeus (bearing an inter¬ 
rupted, slender, black, median line), fulvous, and with two fine 
short green lines between the eyes. The head above is dirty buff, 
with the hind part black; the prothorax is black and shining in 
front, with a green tinge at the sides, behind the lateral spines,
