middle) on the thorax and abdomen, the legs and the hairs of the 
hind tarsi are black, the tips of the hind femora and hind tibie 
are pitchy red and curved. The anterior tibiz are simple in the 
males. Specimens are in the Museum of the Jardin des Plantes, 
and of M. Dupont of Paris. 
Genus CHROMOPTILIA. Westw. 
I have no hesitation in regarding the insect represented in 
figure 3, as the type of a group distinct from Schizorhina. The 
form of the prothorax is altogether unlike that of any of the 
known Cetoniidx ; and it will be remembered that the form of this 
portion of the body is one of the most important characters in the 
group. The species has, indeed, been regarded by more than one 
entomologist to whom I have shown it, as one of the Trichiides ; 
but the sinuated sides of the elytra, as well as the structure of the 
mouth, assert its claim to be considered as a Cetoniideous insect ; 
indeed the structure of the clypeus, porrected maxillary lobes, and 
hairy hind feet, point out its relation to Schizorhina, and espe- 
cially to such species as S. plumigera. Figure 3 a represents the 
mandible, 3 4 the maxilla of both sexes destitute of any tooth on the 
inner lobe, and with the upper lobe entire, horny, acute, and very 
setose ; and 3c the mentum, oval in form and deeply notched in 
front. The head is alike in both sexes, and not cornuted. The 
clava of the antennez of the male is slightly more elongated than 
in the female. The mesosternum is short, gibbose, and not at 
all produced (figs. 3d, 3 e), the elytra are broadest at the base, 
each with a strongly elevated costa running down the centre nearly 
to the tip. The legs are long, the fore legs of the male being rather 
longer than those of the female. The anterior tibize are 3-dentate 
in both sexes, those of the female (fig. 3g) being rather broader 
than those of the male (fig. 3); this is the only distinguishing 
external character which I can find, as the abdomen of the male is 
not longitudinally channeled: the hind tibize are slightly spurred 
beyond the middle in both sexes. The hind tarsi, in both sexes, 
are long, and clothed on each side with bundles of very long hair, 
those on the outside of the last two joints of the tarsi being bright 
fulvous, whilst all the others are black.
