MADAGASCAR CETONIIDyE. 
and the African group* typified by Cet. bimaculata, DeGeer. (flavo- 
maculata, Aucfc.), and especially to the genus Lophorrhina, Burm. 
MSS. .(Cetonia 5-lineata, F. and pentachordia, Klug), also from 
Africa, (but unknown to Mac Leay,) which, like the present genus 
possesses tridentate anterior tibise in both sexes. 
Genus PLJESIORRHINA, Burnt., MSS. 
Plcesiorrhina reflexa , (Plate 32, fig. 1.) 
Syn.— Cetonia ( Goliath) reflexa , Gory and Percheron (Descr. de quelq. nouv. Esp. de 
Cetoines de Madagascar, in Silb. Rev. Ent. 1835, No. 15). 
The large size of the head of the male of this species, with its 
dorsal and lateral horns, render it a very conspicuous insect. It is 
but moderately shining, and but very slightly punctured, being of 
a black colour with a greenish tinge, except the pronotum and 
elytra, which are slightly tinged with blue; the dorsal horn of the 
head has a castaneous central line down the centre, the sides of the 
pronotum are castaneous as well as the two spots on the posterior 
margin; the base of the metacoxae and the exposed part of the 
mesosternum are luteo-castaneous. The general colour of the under¬ 
surface of the body is a dark apple green. The femora and 
reflexed undersides of the pronotum luteo-fulvous, with a slightly 
greenish tinge. Fig. 1 a represents the head of male, seen from the 
side, and 1 b from beneath ; 1 c, the maxilla of the male, the lower 
lobe destitute of any tooth ; 1 the mentum, deeply channeled 
parallel to the tip (as in the typical Goliathi), concealing the base 
of the labial palpi ; 1 c, the mesosternum seen laterally, and 1 f 
seen from beneath ; 1 g , the head of the female, and 1 li , the fore 
tibiae of the same sex. The female has the four posterior tibiae also 
more strongly spurred, beyond the middle, than the males, and the 
mesosternum broader and somewhat more triangular. 
The female of Goliath ochreata, G. and P., has the sides of the 
head straight, the front part forming a short triangle with the 
point in front; the inner lobe of the maxillae is much broader than 
in PL reflexa <£, but without any tooth ; the mentum is very 
similar in shape and structure to that of Tmesorrhina concolor 
(pi. 19, fig. 3 c), being, however rather broader, and the mesoster¬ 
num is considerably more porrected than in PI. reflexa. It is in the 
collection of the Rev. F. W. Hope.
