Not illustrated. 1898 edition. Excerpt: ... which there was no evidence of any such modification. The choice of Pieris rapce as a representative of the Pieridae was unfortunate, for all traces of this splitting back of 7?4+5 have disappeared from both pupal and adult wings, while the adult wings of Eurymus philodice and Anthocharis sara show these traces very well preserved and it is therefore very probable that, had their pupae been examined, the split-back condition of i?4+c would have been found (pl. Lxi1, figs. 31 and 32). On the other hand, Feniseca was probably as good a type as the North American Lycaenidae could furnish, for the vein reduction has proceeded to such an extent in this family that very few of its members retain any traces of this modification. The forms in my possession which do retain such traces come from South America and southern Asia (pll. Lxii1, fig. 33). The wide occurrence of these vestiges, which are clearly remnants of a split-back condition of the vein Ri+5, renders entirely justifiable the interpretation of similar structures in related forms as homologous and signifying the same condition. These vestiges occur in all families and in the following examples they are especially well marked: Epargyreus tityrus of the Hesperidae; Papilio polyxenes of the Papilionidae; Parnassius smitheus of the Parnassidae; Hypatus bachmani of the Libytheidae; Anosia plexippus of the Danaidae; Leucothyris quinatina of the Neotropidae; Apostraphia charithonia of the Heliconidae; Semnopsyche diana and Euphydryas phaeton of the Nymphalidae; Catoblepia sp. of the Brassolidae; Morpho sp. of the Morphidae; Erebia tyndarus of the Satyridae; Anthocharis sara of the Pieridae; Arhopala hercules of the Lycaenidae (pls. Lx-lxii1, figs. 18, 22, 34, 35. I2, 38, 14, 13. 37, 36, 39....
