Habitat in Africa tropicali. Gold coast. In mus.,D. Raddon. 
Considerably larger than any of the other species of Eudicella, the male having the upper 
surface of the body of a splendid opaline green, strongly tinged with coppery orange ; the 
insect when held towards the light appearing entirely green, while when held from it, it appears 
of a rich coppery red. 
The head has less of the coppery hue, it is almost flat above and nearly quadrate; it is 
closely punctured, the punctures being quite visible to the naked eye. From the base of 
each antenna runs a sinuated dark slender impression, almost parallel with the inner margin 
of the eye ; the anterior angles of the head are produced into a short diverging spine, directed 
upwards, of a brown colour, black at the extreme tip, and obliquely truncate within, Be- 
tween each of these spines and the middle of the head is a deep oval impression of a green 
colour. The space between these two impressions is occupied by a triangular brown patch 
running backwards from the middle of the front of the head, which is produced into a long 
luteous-brown horn, the base of which is darker reddish brown, and nearly straight, being 
elevated in a slight curve, at the extremity of which the horn is divided into two branches, 
which follow the curve of the basal part, each terminating in a point, behind which are 
several (three or four) black tubercles; the furcation of these two branches forming a regular 
curve when seen from behind. The entire horn is more than double the length of the head. 
(Fig. la, 1, Jc, the horn seen in different positions.) The eyes and the antenne are 
black, the palpi pitchy, the maxillary being paler than the labial. 
The pronotum is, at the hind part, half as broad again as it is long, and is very finely and 
closely punctured, especially at the sides and fore-angles, the punctures being scarcely visible 
to the naked eye ; it is slightly dilated in the middle of the sides, which have slender 
thickened magins. Near the base of the scutellum are two slight impressions. The scutel- 
lum and elytra are covered with excessively fine punctures not visible to the naked eye; the 
latter has two lines of deeper punctures running along the sides of the suture. This is 
elevated at the extremity of the elytra, where it has a slender black margin and terminates in 
two points. The sides of the elytra are concolorous, the middle of the raised humeral part 
appearing rather darker, but not in the least marked with the black spot observable in the 
other species. The base of the elytra is rather broader than the hind part of the thorax. 
The elytra are one fourth longer than broad. The underside of the body is green tinged with 
coppery orange, especially across the middle of the metasternum ; this has a dark longitudinal 
line in the centre, and the sides are thickly punctured. The underside of the femora 
are marked with minute slender dark oblique strie; the femora on the upper side 
are entirely castaneous red; the anterior with a thick coating of hairs along the edge. 
The tibia are castaneous brown, very slightly tinged with green; the anterior curved and 
irregularly dentate along the inner edge. The tceth, spines, and tarsi are black ; the tibize 
beneath are dark brown. The anterior extremity of the metasternum is green, whilst the 
base of the mesosternum is coppery, (fig. 1 d, 1 e, sternal process). The abdomen beneath 
is green, with the slender margins of the segments dark brown. The centre of the abdomen 
has a deep impression, which is dark along the middle.
