CETONIIDA OF AFRICA. ulyyil 
the apical (mesosternal) portion, small, and not wider than the 
extremity of the metasternal portion. 
Nearly every species in the group thus naturally associated is dis- 
tinguished by splendid green or golden colours. This is, in fact, the 
case with all those which are natives of the tropics ; but I have re- 
ceived, within the few last days, two species from Mr. Melly from 
a more southern latitude, both of which exhibit white velvet-like 
patches, and one of them is entirely destitute of metallic tints. 
In the Coleopterist’s Manual of Mr. Hope (vol. i, p. 119) a genus 
was proposed under the name of Dicronorhina, comprising Cetonia 
micans, Daphnis and Grallii, characterised by the internally spinose 
fore tibize of the males. As however several species are now known, 
(D. Nireus, Burkei, 4-maculata and guttata) the males of which 
possess unarmed fore tibize, I have considered it as likely to lead to 
less confusion by uniting them under a different generic name. 
The group now proposed, comprises Mr. MacLeay’s sub-sections 
3, 4, and 5 of the section ‘Goliathi Smithii, and his 4th sub- 
section of Coryphe Naricize, with several other species which must 
have been formed into other sub-sections according to his arrange- 
ment. 
By Dr. Burmeister they are formed into the genus Dicronor- 
rhina, and portion of Ceelorrhina, which are, as it appears to me, 
unnaturally placed in different sections of his family Goliathide. 
They may be formed into several sections as follows :— 
A. Tibi antice ¢ intus denticulate. 
a. Clypeus ¢ in cornu obtriangulare porrectus < - (1. Dieronorhina, Hore.) 
3 ee furcatum porrectus 5 . . (2. Eudicella, Wuirr). 
B. Tibix anticz intus haud dentate. 
a. Clypeus ¢ in cornu obtriangulare medium porrectus. 
a. Corpus haud metallicum, tarsi antici ¢ pee peni- 
cillato . p . (3. Cheirolasia, Westw.). 
8. Corpus metallicum fart antici haud penicillati. 
* Caput & cornu postico armatum clypeus 
© haud recte truncatus. . (4. Taurhina, Burm.). 
** Caput ¢ haud cornu postico armatom 5 
clypeus 9 recte truncatus. - . (5. Ca@lorrhina, Burm.). 
b. Clypeus ¢ in cornua duo lateralia porrectus : . (6. Stephanorr janes Burm.). 
Secrion 1.—DICRONORHINA, Hope. 
The first of these sections, which has for its type the typical 
species of Mr. Hope’s genus Dicronorhina (a name altered by 
Dr. Burmeister to Dicranorrhina), namely the Cetonia micans of 
Drury, is further characterised by having the inner lobe of the 
maxille in both sexes destitute of a tooth, which is found, at least
