extremely wide apart. Hmdwivg triangular; tlie costal margin long, apex somewhat 

 angularly convex, exterior margin very oblique and convex anteriorly ; cell extremely 

 long, witli a large oval ochreous up;per-discoidal jMtch extending irom. near the base 

 and above the subcostal to near end of cell, clothed with densely packed broad 

 round-tipt ribbed scales ; antennge rather thick, with imperceptibly increased tip. 



Lakva with three pairs of fleshy filaments. 



Type. — E. Corns, Fabricius. 



Historical Note. — The genus Euploea, as established by Fabricius (Illiger's 

 Mag. 1807, p. 280), consisted of three species — Phxipims, Similis, and Corns — the 

 two first named species belonging to the group Limnaina. Plexippris became the 

 type of Latreille's genus Danaida in 1805, and Similis that of the genus Radena in 

 1880, thus leaving Corns as the remaining species, and consequently the type, as 

 specified in the ' Monograph of the EuploeiuEe ' in Proc. Zool. Soc. Lond. 1883, 

 p. 289. This late period in the determination of the type of Euploea had been caused 

 by an erroneous identification, by Hiibner (Verz. p. 16), Doubleday (Gen. D. Lep. 

 p. 88), Kirby (Syn. Catal. p. 10), Scudder (Historical Sketch of generic names of 

 Butterflies, p. 172), Butler (J. Linn. Soc. 1878, p. 29J), and Moore (Lep. Ceyl. i. 

 p. 11) ; each of these authors, in the works cited, having taken the Corns of Fabricius 

 to be the same species as the Gore of Cramer (Pap. Exot. iii. pi. 266, fig. B, F). Both 

 Mr. Scudder (I.e.) and Mr. Butler (I.e.) citing Cramer's Core as the typical represen- 

 tative of the Fabrician genus Euploea. This erroneous identification I also followed 

 in the "Lep. of Ceylon," p. 11. Subsequently, on going more fully into the study of 

 the entire group of Euploeinge (see Monograph in P. Z. S. 1883), and then finding that 

 Mr. Butler (Catal. Fabrician Lepidoptera, p. 1) had, in 1869, stated the E. Corns of 

 Fabricius to be a " local form of the E. pJicenareta," and " has evidently no connec- 

 tion with the Core of Cramer," and that this important fact had been over- 

 looked in his subsequent revision of the group published in the Linnean Journal in 

 1878. On comparing the descriptions of these two species their distinction was at 

 once seen, — Corns being then identified as the female of the Ceylon form named EHsa, 

 and pertaining to a different section of the group from that in which Core has been 

 placed.
