Family 13— LYC^ENID^E. (39 Genera, 1,220 Species.) 



General Distribution. 



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

 regions our own " Blues " and " Coppers " give biit 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. 

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

 teristic of the Palasarctic and Nearctic regions, but straggling: 

 species occur also in North India, South Africa, Chili, and New 

 Zealand. Thccla is especially characteristic of the Neotropical 

 region, where there are about 370 species; in the Nearctic 

 region, 36 ; in the Pala?arctic 13 ; and in the Ethiopian 3. 

 Miletus, Lucia, Hypolycama, Myrina, and Dcudorix are common 

 to the three tropical regions of the Eastern Hemisphere — the 

 Ethiopian, Oriental, and Australian. Aphneus and lolaus are 

 common to the Ethiopian and Oriental regions, the latter 

 extending to Celebes. Ialmcnus, Pscudodipsas, Curctis, and 

 Amllypodia 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, Eumccus in the 

 Nearctic and Neotropical regions. The Nearctic region has one 

 peculiar genus (Fcniseca) ; the Pahearctic has two — Thcstor and 

 Lccosopis ; the Ethiopian has nine — Pentila, Liptana, D'Urbania, 

 Axiocerces, Capys, Phytala, Epitola, Hcwitsonia, and Deloneura ; 

 the Oriental has five — Allotinus, Ilerda, Poritia, Camena, and 

 Liphyra ; the Australian has three — Hypoclirysops, Utica, and 

 Ogijvis ; and the Neotropical also three — Lamprospilus, Theorema, 

 and Triclwnis.
