IDEOPSIS. 15 



Our representative of this group of genera is — ■ 



HESTIA IDEA. 

 (Plate IV, Fig. I.) 

 Papilio idea, Clerck, Icones, pi. 38, fig. 1 (1764) ; Linnaeus, 

 Syst. Nat. (ed. xii.), i., pt. 2, p. 75s, no. 73 (1767); 

 Cramer, Pap. Exot., iii., pi. 193, figs. A., B. (1767). 

 Idea agelia, Godart, Encycl. Meth., ix., p. 195, no. 1 (1S19). 



This species is now regarded by the authors who subdivide 

 ITesfia as the type of the genus Nedaria. It is a native of 

 the islands of Amboina and Ceram. Our figure represents this 

 species of half the natural size. There are so many allied 

 forms that a detailed description cannot be given. 



GENUS IDEOTSIS. 

 Ideopsis, Horsfield & Moore, Cat. Lep. Mus. E. Tnd. Comp., 

 i., p. 333 (1857) ; Schatz, Exot. Schmett., ii., p. 80 (1886). 

 This genus derives its name from the resemblance of I. daos 

 (Boisduval) to Hestia idea (Clerck) ; but the species of Ideopsis 

 are smaller than those of Hestia, and have the club of the 

 antennae more distinctly thickened. Some species of Ideopsis, 

 however, have more pointed brown wings, with the hind-wings 

 and the disc of the fore-wings of a slightly transparent grey 

 or yellow. 



IDEOPSIS DAOS. 

 [Plate IV, Fig. 2.) 

 Idea daos Boisduval, Spec. Gen. Lepid., i., pi. 24, fig. 3 

 (1836). 

 The true Ideopsis daos is a native of Borneo. I abstain from 

 quoting more synonymy, as it is still uncertain whether some 

 of the Butterflies from South China, Malacca, Sumatra, &c, 

 which are usually referred to I. daos may not be distincj; 

 species.
