( 113 ) VIII. Heterocerous Lepidoptera collected in Chili by Thomas Edmonds, Esq. By Arthur G. Butler, F.L.S., F.Z.S., &c. [Read AprU 5th, 1882.] Part II.— NOCTUITES. Mr. Edmonds obtained forty-five species of Noctuites, many of them being represented by fairly long series, so that it is possible to judge with some measure of certainty as to how far the species are liable to vary : in a few instances I have been obliged to consider as distinct, forms which Mr. Edmonds evidently only regarded as varieties, but it would be indeed remarkable if the collector should be always correct in his views as to the extent of variability in each species. It is a singular fact that since Walker's time no species of the present tribe have been described from Chili ; the nearest approach to descriptions of Chilian Noctuites being found in Berg's ' Patagonische Lepidopteren beobachtet auf eine Reise im Jahre 1874 ' (Bull. Mosc, 1875), and in a short paper by myself on the Lepidoptera obtained at the Straits of Magellan by Dr. Coppinger, of H.M.S. 'Alert' (Proc. Zool. Soc, 1881); but none of the new species described in these two papers are iden-tical with any of those obtained by Mr. Edmonds. The following is an account of the species : — LEUCANIID^. Leucania, Ochs. 1. Leucania impuncta. Leucania impuncta, Guenee, Noct., i., p. 83, n. 117 (1852). Var. Leucania decolorata, Blanchard, in Gay's ' Chili,' vii., p. 81, n. 1 ; pi. 4, fig. 9 (1854). Evidently a very common species : the figure by Blanchard does not give the faintest idea of the species, trans, ent. soc. 1882. — part ii. (july.) q
