ON NEW AND LITTLE-KNOWN BUTTERFLIES. 237 



Its name occurs but rarely in the literature of butterflies. Dr. h. G. 

 Butler records it correctly from China as a Crastia^ Dr. F. Moore in 

 1883 gives it from China, but places it incorrectly in his genus 

 Tronga, and Herr H. Fruhstorfer incorrectly records it from East. 

 Java. As regards its synonyms, Dr. Felder re-described it as E, 

 lorquinii from Southern China, and Dr. A. G. Butler as E.felderi 

 from Hongkong and Sumatra, the type specimen being apparently 

 from Sumatra. The association of these two habitats is unfortunate, 

 no species of Euplcea occurring both in China and Sumatra as far as 

 I am aware. If the " type " of E. felderi is a Sumatran insect, the 

 synonymy should read '' E. felderi^ part. " Dr. Butler has noted 

 that E. felderi " is the E. lorquinii of Felder ". Mr. James J. 

 Walker in his Preliminary List of the Butterflies of Hongkong 

 records it as Euplvea (Crastia) frauenfeldii, var. a lorquinii^ Felder, 

 and says that the larva feeds on Strophanthus divergens. Lastly, 

 Dr. Moore has described and figured it from " a single male, in 

 the collection of the British Museum, which was taken at Trincomalee 

 on the north-east side of the island. " I am very incredulous that 

 this specimen ever came from Ceylon*; moreover the true E. frau- 

 enfeldii is a Nicobareese species, and a synonym of it is the E, esperi of 

 Felder, as Felder has himself admitted. 



2. EuPL(EA {Chirosa) era, n. sp. Plate FF, fig. 2 ^. 



Habitat : Santa Cruz, one of the Solomon Isles. 



Expanse : ^,2*9 and 3*1 inches. 



Description : Male. Near to Euplcea [^Chirosa] netscheri Snellen, 

 Tijd. voor Ent., vol, xxsii, p. 384, pi. VIII, fig. 3, male (1889), from 

 New Guinea (Snellen), in my collection from Humboldt Bay and 

 Andai, in the north-west of that island, and from Stefansort, in Ger- 

 man New Guinea, from which it differs on the upperside of both loings^ 

 having the ground-colour darker, and the margins paler, much less 

 rufous, and narrower. Forewing has the sexual brand straight instead 

 of curved. Bindioing has the dark-ground colour " very much more 

 extensive, occupying two-thirds of the area instead of about one-third. 

 Underside both wings with the same differences as on the upperside ; 

 the markings the same as in E, netscheri, they consist of a small 

 bluish-white spot in the discoidal cells, the forewing with two small 

 spots beyond the cell divided by the third median nervure, and a
