BUPRESTIS BICOLOR. 
PLATE VI. Fig. 3 . 
Buprestis bicolor, Fab . — Catoxantha bicolor, Dejean. 
This is the largest and one of the most beautiful spe- 
cies of the splendid tribe to which it belongs. It seems 
to have been very little known to Entomologists of 
the old school, since it is not figured, and seldom 
alluded to, in any of their works. The specific name 
bicolor has no doubt been applied to it on account 
of the striking contrast between the colour of the 
upper and under side. The former is deep brassy 
green, very smooth and glossy ; the latter is light 
brownish yellow. The head has a deep groove 
down the middle, and the greater part of it is oc- 
cupied by the eyes, which are of a deep chestnut 
colour. The thorax is small and depressed, thinly 
covered with minute punctures, and having a cal- 
losity at each of the hinder angles, marked with a 
pretty large triangular spot similar in colour to the 
under side of the body. The elytra are very long, 
and rather convex, punctured anteriorly, each of 
them having four slightly elevated lines running 
along their whole length, and a short oblique one 
near the suture at the base : the colour is brilliant 
brassy green, with faint coppery reflections towards 
the sides, and a large transverse spot of yellowish 
white on each, placed a little behind the middle.
