FAMILY 9.-LIBYTHEIDE, (1 Genus, 10 Species.) GENERAL DISTRIBUTION. ORIENTAL AUSTRALIAN NEOTROPICAL NEARCTIC PALEARCTIC ETHIOPIAN The genus Libythea, which constitutes this family, appears to have its head-quarters in the Oriental region, but extends on all sides in an erratic manner, into various remote and disconnected portions of the globe, as indicated above. FAMILY 10.-NEMEOBIIDÆ. (12 Genera, 145 Species.) This group has been separated from the Erycinidæ of the older authors, and contains all the non-American genera and species. Half the genera and nearly four-fifths of the species of this group are, however, Neotropical; one is European; two or three African; and twenty-six Oriental and Australian. The genera are: Nemeobius (1 sp.), Europe; Dodona (6 sp.), North India; Zemeros (2 sp.), North India and Malaya; Abisara (11 sp.), North India, Malayan and Moluccan districts, Madagascar and West Africa; Taxila (8 sp.), North India and Malaya; Dicallaneura (2 sp.), Moluccan district; Alesa (6 sp.), Eunogyra (2 sp.), Cremna (7 sp.), Baotis (3 sp.), are all from the Brazilian sub-region; Eurybia (10 sp.), Mesosemia (80 sp.), inhabit both the Brazilian and Mexican sub-regions. FAMILY 11.-EURYGONIDE. (2 Genera, 78 Species.) GENERAL DISTRIBUTION. NEOTROPICAL NEARCTIC PALEARCTIC ETHIOPIAN ORIENTAL AUSTRALIAN SUB-REGIONS. SUB-REGIONS. SUB-REGIONS. SUB-REGIONS. SUB-REGIONS. SUB-REGIONS. This small family, separated from the true Erycinidæ by Mr. Bates, is confined to the tropical forest-districts of continental America. The genera are: Eurygona (71 sp.); Methonella (1 sp.); the latter found in Equatorial South America. FAMILY 12.-ERYCINIDÆ. (59 Genera, 560 Species.) This extensive family of small, but exquisitely beautiful butterflies, is especially characteristic of the virgin forests of the Neotropical region, only a few species of three genera extending into the Nearctic region. The more important genera, and those which have an exceptional distribution, can alone be here noticed. Charis extends from Brazil to New York; Apodemia from Brazil to California, Utah, and Oregon; Amarynthis inhabits the Brazilian and Antillean sub-regions; Lepricornis and Metapheles are small genera found only in the Mexican sub-region; Lymnas, Necyria, Ancyluris, Diorhina, Esthemopsis, Anteros, Emesis, Symmachia, Cricosoma, Calydna, Lemonias, Nymphidium, Theope, and Aricoris are common to the Brazilian and Mexican sub-regions. All the other genera (40 in number) are only known from the Brazilian sub-region, and of these a considerable proportion are confined to the damp equatorial forests of the Amazon Valley. FAMILY 13.-LYCANIDE. (39 Genera, 1,220 Species.) The Lycanide-of the variety and beauty of which in tropical regions our own "Blues" and "Coppers" give byt a faint idea -are a group of universal distribution. We shall therefore indicate those genera which are restricted to one or more regions, or are nearly cosmopolitan. The large genus Polyommatus (containing 325 species) has the same universal distribution as the entire family. Our common " Blues" well represent this genus. Lycana (comprising the "Coppers ") is more especially characteristic of the Palearctic and Nearctic regions, but straggling species occur also in North India, South Africa, Chili, and New Zealand. Thecla is especially characteristic of the Neotropical region, where there are about 370 species; in the Nearctic region, 36; in the Palearctic 13; and in the Ethiopian 3. Miletus, Lucia, Hypolycana, Myrina, and Deudorix are common to the three tropical regions of the Eastern Hemisphere-the Ethiopian, Oriental, and Australian. Aphneus and Iolaus are common to the Ethiopian and Oriental regions, the latter extending to Celebes. Ialmenus, Pseudodipsas, Curetis, and Amblypodia are common to the Oriental and Australian regions, but the first-named is found also in Madagascar. Zephyrus is found only in the Nearctic and Palearctic, Eumaus in the Nearctic and Neotropical regions. The Nearctic region has one peculiar genus (Feniseca); the Palearctic has two-Thestor and Læosopis; the Ethiopian has nine-Pentila, Liptana, D'Urbania, Axiocerces, Capys, Phytala, Epitola, Hewitsonia, and Deloneura ; the Oriental has five-Allotinus, Ilerda, Poritia, Camena, and Liphyra; the Australian has three-Hypochrysops, Utica, and Ogyris; and the Neotropical also three-Lamprospilus, Theorema, and Trichonis. FAMILY 14.-PIERIDE. (35 Genera, 817 Species.) GENERAL DISTRIBUTION. ORIENTAL AUSTRALIAN NEOTROPICAL NEARCTIC PALEARCTIC ETHIOPIAN The Pieridæ are distributed almost, if not quite, as widely over the globe as the last family, and we shall group the genera in the same manner. Pieris (130 sp.) is cosmopolitan; Terias and Callidryas are found in all the four tropical regions, and as far north as Pennsylvania in the Nearctic region; Pontia, Tachyris, Eronia, and Thestias are common to the Ethiopian, Oriental, and Australian regions, the last-named, however, only extending as far as Timor; Colias is pre-eminently Palearctic and Nearctic, with a few Ethiopian species, one Indian, two in Chili, and one in the Sandwich Islands; Anthocharis is wholly Palearctic and Nearctic; Midea has two species Nearctic, and one in Japan; Gonepteryx is Palæarctic and Neotropical, extending into Texas; Idmais and Callosune are Ethiopian and Oriental; Thyca and Iphias are Oriental and Australian; Meganostoma is Nearctic and Neotropical; Nathalis and Kricogonia are Neotropical, ranging into Florida, Texas, and Colorado. The The peculiar genera are pretty equally distributed. Neotropical region has ten, two being confined to Chili; Euterpe and Leptalis are the most remarkable, the latter containing a number of forms mimicking the Heliconidæ and Danaidæ. The Oriental region has two, Prioneris and Dercas; the Australian one, Elodina; the Ethiopian two, Teracolus and Pseudopontia; the Palearctic two, Leucophasia and Zegris; the Nearctic one, Neophasia. FAMILY 15.-PAPILIONIDE. (13 Genera, 455 Species.) The Papilionidæ, comprising many of the noblest and richestcoloured butterflies, and long placed at the head of the group, are almost as universally distributed as the Pieridæ, but they do not extend to so many remote islands nor so far into the Arctic and Antarctic regions. Nine-tenths of the species belong to the genus Papilio, and these are especially abundant in tropical regions, although species occur in every region and every subregion. Well-marked sub-divisions of this large genus are characteristic of each great region-as the " Æneas" group in the Neotropical, the "Paris" group in the Oriental, the "Egeus" group in the Australian, the “ Zenobius ” group in the Ethiopian, and many others. The few species of the Palæarctic region belong, on the other hand, to a group of universal distribution, and the Nearctic has a good number of species allied to Neotropical forms. The other genera have mostly a very restricted range. Parnassius is an Alpine genus, confined to the Palearctic and Nearctic regions. The Palearctic region further possesses 5 peculiar genera-Mesapia, Hypermnestra, Doritis, Sericinus, and Thais; the Oriental has 4, Calinaga, Teinopalpus, Bhutanitis, and Leptocircus, the latter going as far as Celebes; the Australian has 1, Eurycus; and the Neotropical 1, Euryades, confined to the Chilian sub-region. The Ethiopian and the Nearctic regions have no peculiar genera. |
