Show 1871.] MR. A. G. B U T L E R O N N E W L E P I D O P T E R A . 83 wings with a narrow, central, oblique crimson band; apex white-tipped. Body brilliant metallic green; fringe white-flecked at apex and near anal angle; wings below nearly as above ; the hind wings with two red points placed obliquely immediately beyond green area. Body-thorax brownish, legs streaked with white; abdomen with central scarlet band, surrounded with brown, and interrupted by whitish annulations. Expanse of wings 2 inches 5 lines. Hab. Venezuela (Dyson). B.M. _ Allied to E. glauca of Cramer, from Surinam, but perfectly distinct. The nearest approach to the type form in the British Museum is an example from Ega, with red-tinted white band in front wings; but even in this example the band of hind wings is different in form and position. Genus PH_EGORISTA. P H _ E G O R I S T A SIMILIS, Walker. 6*. Wings above crimson; front wings with apical area dark brown, a subapical fasciole, a spot near the anal angle, and the internervular fringes white. Hind wings with moderately broad dark-brown outer margin; fringe white-spotted. Thorax dark brown, white-streaked ; antennae dark brown ; base of the abdomen orange, apex orange-tinted, central portion black, with white annulations. Below nearly as above. Expanse of wings 2 inches 11 lines. Hab. Fantee, Cape Coast (Ussher). Coll. Swanzy. This is doubtless an imitation of Atelis helcita of Linnaeus, which it closely resembles. The female is described by Mr. Walker. Genus DIRPHIA*. D I R P H I A V E N A T A , n. sp. Wings above smoky brown; the internal area of front wings and the whole of the hind wings (excepting the margin) in male whitish brown; nervures blackish, especially in front wings ; a large rounded black spot at end of hind-wing cell. Body above smoky brown; metathorax of male clothed with lighter hairs; antennae ferruginous ; wings below more uniform in colour, the markings scarcely defined. Body below dark smoky brown. Expanse of wings : _T 4 inches, $ 4 inches 4 lines. Hab. Buenos Ayres (Burmeister). B.M. This handsome species is nearly allied to a female insect deseribed by Mr. Walker as that sex of Heliconisa impar; its natural position in the genus is probably near D. ursina. I would propose for the female placed with H. impar the name of Dirphia lancea. * A third allied Dirphia has been characterized and figured by Blake Ent. Soc. Philad. 1864) as a new genus and species under the name of Coloradia pandora. |
