The splendid addition to the family of the Goliath Beetles, 
represented in the annexed Plate, has been recently discovered in 
tropical Western Africa, by Dr. Savage, and at his request I have 
added coloured figures of both sexes of it to my former articles on 
this tribe of insects, although a previous description has appeared 
from the pen of the talented Dr. T. W. Harris, of Harvard Uni- 
versity, Boston, U.S. It is closely allied to the two other species 
of Mecynorhina, but differs from M. torquatus in its striped thorax, 
maculated elytra, and furcate horn of the clypeus, in all which 
respects it is nearer to M. Polyphemus, which is at once known 
from it by the dark green ground colour of the elytra, anterior tibice 
of the males multidentate on the inner edge, and especially by the 
black colour of the posterior tarsi and the emarginate clypeus of 
the female of the Polyphemus. 
The male has the head in front of the eyes armed with two 
porrected black horns, bent outwardly, and the front of the head 
is produced into a horizontally porrected broad horn, furcate at 
the tips; the head and upper surface of the frontal horn are 
entirely clothed with a very fine grayish plush or slight velvety 
knap, the underside of the latter dark chesnut black; the two 
other horns are black. The disc of the head is considerably exca- 
vated. The thorax is dark opaque velvety green above, with five 
broad yellowish stripes, the two intermediate ones rather dilated 
in the middle, and the lateral ones having only a very slender — 
black margin. The scutellum is dark green, with a broad yellow 
stripe along the middle. The elytra are velvet black, each with 
three longitudinal rows of fulvous spots, and an irregular stripe of 
the same colour on each side of the suture, the marginal and sub- 
sutural spots confluent from the base to the middle. Each elytron
