Family Id.—LYCJE^IDM. (39 Genera, 1,220 Species.) 



The Lycsenidse — of the variety and beauty of which in tropical 

 regions our own " Blues " and " Coppers " give bi^t a faint idea 

 — are a group of universal distribution. We shall therefore in- 

 dicate those genera which are restricted to one or more regions, 

 or are nearly cosmopolitan. The large genus Polyommatus (con- 

 taining 325 species) has the same universal distribution as the 

 entire family. Our common " Blues " well represent this genus. 

 Lycmna (comprising the " Coppers ") is more especially charac- 

 teristic of the Palsearctic and Nearctic regions, but stragglinsf 

 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 Palsearctic 13 ; and in the Ethiopian 3. 

 Miletus, Lucia, Hypolycccna, Myrina, and Deudorix are common 

 to the three tropical regions of the Eastern Hemisphere — the 

 Ethiopian, Oriental, and Australian. -ApJineus and lolaus are 

 common to the Ethiopian and Oriental regions, the latter 

 extending to Celebes. lalmenus, Pseudodipsas, Ouretis, and 

 AmUypodia 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 Palsearctic, Uumcetis in the 

 Nearctic and Neotropical regions. The Nearctic region has one 

 peculiar genus {Feniseca) ; the Palsearctic has two — Thestor and 

 Lmosopis ; the Ethiopian has nine — Pentila, Liptana, D'Urhania, 

 Axiocerces, Capys, Phytala, Epitola, Heivitsonia, 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 — Zamprospilus, Thearema, 

 and Trichonis.
