Among the beetles which have as yet been met with nowhere else, and are therefore considered peculiar to the country, may be named: a Cicindela, between hybrida and maritima; a Carabus of the form of the cancellatus Illig., with black feelers and legs; C. Clerkii N., and another, green, with gold border, of the form of the catenulatus, caught near the line of perpetual snow on the volcano Awatscha: C. Hoffmanni N., Nebria nitidula, which is the same as the Carabus nitidulus Fabr., as appears by that preserved in Banks's Museum, hitherto the only specimen in Europe; great numbers of these are found in the valleys: a second black sort was caught on the volcano.
Among the coleoptera, the Stachylinus is a rarity: the white-winged Cicindela nivea of Kirby is to be found in great abundance on the sand of the beach, which is of the same colour as itself; the Cic. nodicornis and angusticollis Dej. on the other hand, frequent the paths in the forests. Cosnania, which supplies the place of our Elaphrus, is found among the grass by the side of brooks.
On dead trunks overhanging the water and on the banks and foliage, I obtained three very pretty species of Cicindela, quite distinct in size, form, and colour, but having an almost identical pattern of pale spots. I also found a single specimen of a most curious species with very long antennae.
The beautiful Cicindela gloriosa, of a very deep velvety green colour, was only taken upon wet mossy stones in the bed of a mountain stream, where it was with the greatest difficulty detected. Where the sandy beach was coralline and nearly white, I found a very pale Cicindela; wherever it was volcanic and black, a dark species of the same genus was sure to be met with.
Both these insects are abundant, and we may fairly conclude that the protection they derive from this strange concealment is at least one of the causes that enable the race to flourish. Many of the species of Cicindela, or tiger beetle, will illustrate this mode of protection.
About the roads in the forest, I found the large and handsome Cicindela heros, which I had before obtained sparingly at Macassar; but it was in the mountain torrent of the ravine itself that I got my finest things.
But my finest discovery here was the Cicindela gloriosa, which I found on mossy stones just rising above the water. After obtaining my first specimen of this elegant insect, I used to walk up the stream, watching carefully every moss-covered rock and stone.
Of these the most interesting are: a large predacious nocturnal bug, shining black, with red wings; a nocturnal Cicindela, a beautiful insect, with dark green striated wing-cases and pale red legs; also several diminutive wingless wasps. Of the last I have counted six species, most of them marked with strongly contrasted colours, black, red, and white.
Our common Cicindela campestris frequents grassy banks and is of a beautiful green colour, while C. maritima, which is found only on sandy sea-shores, is of a pale bronzy yellow, so as to be almost invisible. A great number of the species found by myself in the Malay islands are similarly protected.
A few glass tumblers inverted above as many of these larger holes during the summer will intercept the winged sprite into which he is shortly to be transfigured a brilliant metallic-hued beetle, perhaps flashing with bronzy gold or glittering like an emerald the beautiful cicindela, or tiger-beetle, known to the entomologist as the most agile winged among the coleopterous tribe; known to the populace, perhaps, simply as a bright glittering fly that revels in the hot summer sands of the sea-shore or dusty country road, making its short spans of glittering flight from the very feet of the observer.
