Show 1883.] MR. F. MOORE ON LIMNAINA AND EUPLCEINA. 289 extremely oblique thence to the base ; cell very broad ; discocellulars concave, discoidal spur obsolete : hind wing triangular; the costal margin long, apex somewhat angular, exterior margin regularly convex; with a large oval pale upper discoidal glandular patch. Type E. corus, Fabr. Note.-Hiibner (Verz. p. 16), Doubleday (Genera D. Lep. p. 88), Scudder (Hist. Sketch of Generic Names of Butterflies, p. 172), Kirby (Syn. Catal. p. 10), and Butler (Linn. Journ., Zool. xiv. p. 291) have each taken the P. core of Cramer to be the same species as the P. corus of Fabricius, both Mr. Scudder and Mr. Butler citing core as the typical representative of the Fabrician genus Euplcea. Mr. Butler, however, though having previously (Catal. Fabrician Lep. in British-Museum Collection, p. 1, 1869) noted that the P. corus of Fabricius had no connexion with the P. core of Cramer, and referred the former species to a local form of the female of Euplcea phce-nareta, subsequently overlooked this important fact in his revision of the group published in the ' Linnean Journal,' wherein the P. core of Cramer is cited as typically representing the genus Euplcea. This erroneous identification I myself followed in the recently published part of the 'Lepidoptera of Ceylon,' i. p. 11. Having since gone more fully into the study of the entire group of these interesting Butterflies, the distinction of the two above-cited species (corus and core) became apparent to me, the comparison of the descriptions resulting in the determination that the Fabrician species corus is identical with the female of Macroplcea elisa, a totally different insect and pertaining to a different section of the group, from that of the core of Cramer. 1.
