164 ON THE GOLIATH!DEOUS 
robust galea of the maxille, and the comparatively shorter fore-feet 
of the males. 
HYPSELOGENIA, Burmeister. 
This genus is composed of two species, whose affinities have, 
until recently, been imperfectly understood; Gory and Perchéron 
placing them with Diplognatha, whilst Mr. MacLeay, who did not 
correctly examine the structure of their maxille, referred them to 
his Czelocephalous section of Ichnostoma; (Ceton. of South Africa, 
p- 43). By Dr. Burmeister their true structure has been observed, 
and their affinity to Goliathus (long ago pointed out by Latreille 
and others), satisfactorily established, in his beautiful work entitled 
‘Genera Insectorum.’ They are of small size, and natives of Southern 
Africa. The clypeus is moderately cornuted, the dise of the head 
being concave, terminated in front by an ob-conical, porrected, and 
erect lobe. The fore-feet of the males are scarcely longer than in 
the females, and the tibiz in both sexes are externally tridentate, 
the teeth, however, being very obtuse in the males. The inner lobe 
of the maxillze is not armed with a tooth.

GOLIATHUS, Lamarck. 
The insects of this genus are indeed well entitled to the generic 
name, which Lamarck gave to them by making use of the specific 
name which had been given to one of the species by Linneus. 
Dr. Harris, the most distinguished of living American entomolo- 
gists, adopting the opinion which has been entertained with much 
justice by many recent writers, of the injustice of such a system of 
nomenclature, has proposed to restore the specific name Goliata, 
and to substitute that of Hegemon instead of the present generic 
name. Perfectly agreeing with Dr. Harris in his opinion of the im- 
propriety of such nomenclature, I yet do not adopt his generic name, 
because I also consider that when such an improper substitution of 
names has been universally adopted for nearly half a century (as in 
this case), it would not be advisable to alter it. 
From Hypselogenia the true Goliath beetles are distinguished by 
the bifid horns of the clypeus of the males, and the entire clypeus of 
the females. The inner lobe of the maxillz is produced into a sharp 
tooth. The fore tibie of the males are externally destitute of teeth,
