Show 1894.] ON LEPIDOFTERA FROM BRITISH EAST AFRICA. 557 For the present we are content merely to point out the very wide distinctions existing between the genera Chauna and Palamedea. Those who are best acquainted with the anatomy of birds will realize most readily how considerable these distinctions are. W e hope on a subsequent occasion, when we have had the opportunity of examining again and more minutely some points in the structure of Chauna, to deal with the systematic position of the Pala-medeidae. The fact that so great differences obtain between the genera is confirmatory of the generally received opinion that this form is one of great antiquity. 8. On a Collection of Lepidoptera from British East Africa, made by Dr. J. W . Gregory between the Months of March and August 1893. By A R T H U R G. B U T L E R, Ph.D., F.L.S., F.Z.S., & c , Assistaut-Keeper Zoological Department, British Museum (Nat. Hist.). [Received June 8, 1894.] (Plates XXXVI. & XXXVII.) The present collection is rich in species and in number of specimens, though, unfortunately, many of the latter are not in first-rate condition: indeed most of the small moths are unidentifiable. Nevertheless the collection contains several novelties, a fair series of specimens in good preservation, and is particularly interesting as including a considerable number of grades between species which hitherto have been easy to distinguish, but are now clearly shown to be, at most, localized dimorphic developments from one widely-distributed species. Of the species which it has been possible to name, or, at any rate, to assign to their genera, there are no less than 215, of which 10 are described as new to science. Of the remainder several are new to the Museum, whilst others have previously only been represented by single examples. Of Butterflies previously received from Somali-land the collection contains the following :- 1. LIMNAS CHRYSIPPUS (vars. dorippus and klugi). 2. Y P T H I M A ASTEROPE. 3. NEOCCENYRA DUPLEX. 4. JUNONIA (PRECIS) LIMNORIA. 5. JUNONIA CEBRENE. 6. BYBLIA ILITHYIA (Hypanis ilithyia of my Somali paper). 7. HAMANUMIDA DiEDALUS. 8. POLYOMMATUS B^ETICUS. 9. CATOCHRYSOPS OSIRIS. 10. TERIAS ZOE. 11. TERACOLUS HELVOLUS (separated subsequently to the publication of my paper on Somali Lepidoptera). |
