The Goliaths were formerly excessively rare in collections, and of a price inaccessible to ordinary amateurs--one single specimen costing as much as twenty pounds. But for some time the Goliaths of the coast of Guinea and of Cape Palmas have been sold to European amateurs at a modest price, thanks to those travellers who, after the example of Dr. Savage, have collected them by hundreds in the countries which produce them. These enormous Coleoptera are seen on the coast of Guinea fluttering about at the top of trees, the flowers of which they are seeking after. To catch them the trees are felled or else they are shot at with a gun loaded with sand, as is also done for the humming-birds. The species which Dr. Savage made common is the _Goliathus cacicus_, of which we represent the male and female (Figs. 428, 429). It is met with on the coast of Guinea. The _Goliathus Druryi_ (Fig. 430) inhabits Sierra Leone, on the west coast of Guinea. The numerous expeditions which are at the present moment being made into the interior of Africa will not fail to increase the number of species of these splendid insects, which are the ornament of all collections. [Illustration: Fig. 425.--Cetonia argentea.] The group of the _Trichiadæ_, which has in this country and in France a few representatives, is very nearly the same as that of the _Cetoniadæ_. The _Trichiadæ_ have the elytra shorter, the abdomen bigger, and the legs more slender. The _Trichius fasciatus_, which is black, and covered with an ashy down, with the elytra yellow, and with three black bands, is to be met with in quantities on the garden rose-tree, in the months of June and July. The larvæ live in the interior of old beams of wood, respecting their surfaces. In a garden, at a few leagues from Paris, a little wooden bridge had been built. It seemed on the outside to be in a perfect state of preservation. Nothing on the exterior would have led one to think it was possible for the oak timbers which composed it to break down. A good many of them, however, broke suddenly. It was then seen that the wood had been scooped out right up to the surface, which was nothing better than a thin sheet, of an imperceptible thinness. All the interior was full of _Trichii_, in the states of larva, pupa, and perfect insect. [Illustration: Fig. 426.--Goliathus Derbyana.] [Illustration: Fig. 427.--Goliathus Polyphemus.] The _Trichius fasciatus_, sometimes called the Bee Beetle, is very common in the environs of Paris. Geoffroy has described it under the rather quaint name of the "Livrée d'Ancre," because the Marquis of Ancre made his servants wear yellow coats, bordered by braid alternately crossed with green and yellow.
