Show 460 MR. A. G. BUTLER ON THE GENUS EUPTYCHIA. [Nov. 22, clined to consider this form a distinct species, the appearance of the underside being so unlike that of ocirrhoe proper that it would be impossible to place the two insects under one name without such proofs of their apparently specific identity. Even now I am not sure that the two insects might not be separated, as this form differs even from those most closely allied to it in having the front wings more produced, and the submarginal line of the front wings entire to near the apex. 2. EUPTYCHIA LYDIA. (E. ocirrhoe, $ ?) Papilio lydia, Cramer, Pap. Exot. ii. pi. 148. f. C, D (1779) (but not of Fabricius, Ent. Syst. iii. pt. 1. p. 135). Euptychia lydia, Westw. & Hewits. Gen. Diurn. Lepid. p. 373. n. 2 (1851). Satyrus lydius, Godart, Enc. Meth. ix. pp. 464 & 489. n. 40 (1819). Hab. Surinam. The representation of this species may be intended for the female of E. ocirrhoe ; but it is impossible to decide whether it is so or not; and until we know more of the Lepidoptera of Surinam, this and many other Butterflies figured by Cramer must be considered distinct species. 3. EUPTYCHIA OCYPETE. Papilio ocypete, Fabricius, Gen. Ins. Mant. 260(1776); Ent. Syst. iii. pt. 1. p. 96. n. 296 (1793). Euptychia ocypete, Hiibner, Verz. bek. Schmett. p. 54. n. 506 (1816); Westw. & Hewits. Gen. Diurn. Lepid.*p. 373. n. 10 (1851). Satyrus ocypete, Godart, Enc. Meth. ix. pp. 463 & 488. n. 34 (1819). Hab. Surinam. Var. Alar supra paulo glaucar; posticar macula anali nigra fusco pallido cincta. Hab. Venezuela; Para; Tapajos (Coll. Bates). B.M. This species is not perfectly identical with E. helle of Cramer; although Fabricius refers to Cramer's figure of that insect, his description does not in all points agree with it. 4. EUPTYCHIA HELLE. Papilio helle, Cramer, Pap. Exot. iii. pi. 194. f. F, G (1782). Papilio ocypete (synonym), Fabricius, Ent. Syst. iii. pt. 1. p. 96. n. 296 (1793). Euptychia ocypete (synonym), Westw. & Hewits. Gen. Diurn. Lepid. p. 373. n. 10 (1851). Hab. Surinam. Var. Alar posticar supra macula anali distincta bipupillata et ochreo cincta. Hab. Para. B.M. |
