chap, xii.] THE ORIENTAL REGION. 319genera. Morphidae are well represented by the genera Amathusia,Zeuxidia, Discophora, and Thaumantis, some of thespecies of which almost equal the grand South AmericanMorphos. The Nymphalidse furnish us with a host of characteristicgenera, among the most remarkable of which are,Terinos, Adolias, Cethosia, Cyrestis, Limenitis, and Nymphalis,all abounding in beautiful species. Among the LycsenidsB area number of fine groups, among which we may mention Ilerda,Myrina, Deudoryx, Aphneus, lolaics, and AmUypodia, ascharacteristicexamples. The Pieridse furnish many fine forms, suchas Thyca, Iphias, Thestias, Eronia, Prioneris, and Dercas, the lasttwo being peculiar. The Papilionidae are unsurpassed in theworld, presenting such grand genera as Teinopalpus and Bhutanitis;the yellow-marked Omithoptercc ; the superb "Brookiana;"the elegant Leptocercus; and Papilios of the "Coon," "Philoxenus,"" Menmon," " Protenor," and especially the ' green-andgold-dusted' " Paris " groups.The Moths call for no special observations, except to noticethe existence in Northern India of a number of forms whichresemble in a striking manner some of the most remarkableof the above mentioned groups of the genus Papilio, especiallythe "Protenor" group, which there is reason to believe isprotected by a peculiar smell or taste like the Eeliconias andDanaidse.Coleoptera.—The most characteristic Oriental form of theCicindelidse or tiger beetles, is undoubtedly the elegant genusCollyris, which is found over the whole region and is almostconfined to it. Less abundant, but equally characteristic, is thewingless ant-like Tricondyla. Two small genera Apteroessa andDromicidia are confined to the Indian Peninsula, while Theratesonly occurs in the Malayan sub-region.The Carabidas, or ground carnivorous beetles, are so numerousthat we can only notice a few of the more remarkable andcharacteristic forms. The wonderful Mormolyce of the Indo-Malay sub-region, stands pre-eminent for singularity in theentire family. Thyreopterus, Orthogonius, Gatascopus, and Pericallusare very characteristic forms, as well as Planetes and
