182 GOLIATHIDEOUS CETONIIDA 
legs in the male are scarcely longer than in the females, with the 
tibiee bidentate at the tip, those of the females being 3-dentate. 
The elytra are terminated by two sutural spines, the dise being 
more or less marked with white dots.

(Schizorhina c.) pl. 27, fig. 6.

BOTHRORRHINA, Burmeister. 
By an accident, the typical species of this group was illustrated 
by me in a previous Number (p. 126) under the name of Plesior- 
rhina, a name given by Dr. Burmeister to a different (subsequently 
mentioned) group. It comprises two species, natives of Madagascar, 
of great rarity. 
Species 1.—Bothrorrhina refilera, Burmeister. 
Syn.—Celonia (Goliath) reflexa, Gory and Perchéron, op. cit. supr. 
Plesiorrhina reflexa, ante, p. 126, and plate 32, fig. 1 and details. 
Srecres I1.—Bothrorrhina ochreata, Burmeister, Gory and Perchéron (op. cit. sup. 
C. G. ochr.). 
CHORDODERA, Burmeister. 
This group has the front of the head in the males produced into 
a short straight truncated horn, with another flat deflexed truncated 
horn arising between the eyes; the female has the middle of the 
front margin of the clypeus slightly elevated, and an acute trian- 
gular horn arising between the eyes. The maxille have the inner 
lobe acutely pointed. The mentum is rather deeply emarginate. 
The fore tibiz are tridentate inboth sexes. The sternal process is but 
very slightly porrected, and dilated into a short round lobe in front. 
The colours are obscure, the thorax with lines, and the elytra with 
spots of pale pubescence. The species are from tropical Africa. 
Srecrrs I, — Chordodera 5-lineata, Burmeister, Handb. d. Ent. 3, 203, Fabricius, 
Olivier 1, 6, 33, f. 76, (Cetonia 5-/.). 
Species I1.—Chordodera pentachordia, Burmeister, Klug in Erman’s Reise, t. 15, f. 9. 
(Ceton. p.). 
PL/ESIORRHINA, Burmeister (nec. Westw. ante, p. 126). 
This genus is remarkable rather on account of its non-possession 
of striking characters distinctive of the opposite sexes; thus, the 
head is simple, with the clypeus nearly straight in both sexes. 
The maxillz also have both the lobes unarmed. The fore tibize 
are nearly alike in both sexes, and destitute of teeth on the outside*. 
* D. Schaum has erroneously assigned the charaeter of tridentate tibie in both sexes to 
this group. Anal. Ent. p. 42.
