170 ON THE GOLIATHIDEOUS 
Mr. C. Curtis, was published by Mr. Waterhouse, I have seen several 
other specimens in the collection of the Rev. F. W. Hope, one of 
which measures as follows :— 
Length of the head : . 5 : or Ollines: 
3 prothorax . : : Se te ey 
5S elytra . ; : : 5 UG = 
Breadth of hind part of prothorax . Bg) Lear 
3 base of elytra. - . « #18e 33 
The female here figured is also contained in the splendid collection 
of Mr. Hope, having been brought from Sierra Leone by Mr. 
Strachan. Its measurements are as follow :— 
Length of the head. 2 : : . 42 lines. 
a prothorax : 0 etned b Bia ks 
a elytra . : : 5 6 UZeY 
Breadth of the base of the elytra. sheet saligamss 
The male differs from every other Goliathideous insect in not 
having the frontal horn dilated at the tip; this sex possesses no 
tooth on the inner lobe of the maxilla (fig. 1 a), whereas it has a 
very strong one in the female (fig. 2 a); fig. 2 6 represents the 
mentum of the female, and fig. 16 and 1c, the sternal process 
alike in both sexes, the apical mesosternal portion being much more 
developed than in the giant Goliaths. The fore posterior tibize in 
both sexes have their extremities produced into several acute spines 
independently of the calearize, which in the two posterior feet of 
the female are unequal in size, one of them being spatulate in form. 
The reason which induced Schoénherr to change the name of this 
species to C. collaris, (which appears to have perplexed Mr. 
MacLeay, who by the bye cites both the name and reference of 
Schénherr incorrectly) was that there was another C. torquata 
described by Fabricius. As, however, Drury’s name has a long 
priority it ought, even on these grounds, to have been retained. 
As the species is entirely omitted in the ‘‘ Monographie des 
Cétoines,” I have represented both sexes in the accompanying 
plate. 
CERATORHINA, Westwood. 
The following characters at once distinguish a most natural group 
of these insects:— Head of the males with the clypeus (and ocea- 
sionally the hind part of the head) cornuted, simple in the females. 
—Fore-tibiee of the males not dentated on the outside (occasionally 
spinose along the inner edge), those of the females internally simple, 
and externally 3-dentate. Middle tibia of the females with only 
one spine in the middle of the outer margin. Sternal process, with
