Rhynchophorinae of southeastern Polynesia (Coleóptera : Curculionidae).

Abstract: Ten species of Rhynchophorinae are recorded from southeastern Polynesia, including two new species of Dryophthorus from Rapa. Excepting the latter, all the species have been introduced into the area and most are of economic importance. Keys to adults and larvae, notes on biologies, new distributional data and illustrations are presented. This is a combined Pacific Entomological Survey (1928-1933) and Mangarevan Expedition (1934) report. I had hoped to publish the account soon after my return from the 1934 expedition to southeastern Polynesia, but its preparation has been long delayed because of my pre-occupation with other duties. With the exception of two new endemic species of Dryophthorus, described herein, all of the Rhynchophorinae found in southeastern Polynesia (Polynesia south of Hawaii and east of Samoa; see fig. 1) have been introduced through the agencies of man. The most easterly locality where endemic typical rhynchophorids are known to occur in the midPacific is Samoa where there are endemic species of Diathetes. (I consider the Dryophthorini and certain other groups to be atypical Rhynchophorinae). West of Samoa the subfamily becomes increasingly rich and diversified. There are multitudes of genera and species from Papua to India, and it is in the Indo-Pacific where the subfamily is most abundant. Figure 2 demonstrates the comparative faunistic developments of the typical rhynchophorids. I am indebted to the British Museum (Natural History) for allowing me extensive use of the unsurpassed facilities of the Entomology Department and libraries and to the Museum of Comparative Zoology, Harvard University, for use of the library. Photographs 22 and 26 are from the British Museum (Natural History), and all of the other photographs were generously prepared by my friend Dr David Kissinger. LIST OF THE RHYNCHOPHORINAE OF SOUTHEASTERN POLYNESIA

Forest tree and timber insect pests in the Territory of Papua and New Guinea.

Abstract: This is the first comprehensive paper listing the insect pests of commercial forest trees and timbers in the Territory of Papua and New Guinea. Notes on the spe­ cies distribution, biology and control are given, when possible, together with known re­ cords of collection in the Territory. In all, 52+ species are listed, with the following orders represented : Coleoptera (21), Hemiptera (8), Hymenoptera (3), Isoptera (14+), Lepidoptera (5), and Orthoptera (1). Forests cover more than 70 % (32 to 36 million hectares) of the total area of Papua & New Guinea Territory, and of that area at least 8-12 million hectares have considerable industrial potential. The approximate total of the already investigated resources is 2.6 million hectares carrying some 6,100 million superficial meters of merchantable timber, which represents approximately 25 % of the known merchantable forests of Papua and New Guinea (Anon. 1967). Production in 1965-1966 was more than 41 million superficial meters as compared with 5.5 million superficial meters in 1950-1951. The Department of Forests has undertaken a reforestation program of harvested pro­ ductive forests and of rehabilitatin g low value forests and grasslands since 1948. Major plantations are being established at Brown River, Bulolo, Kerevat and Wau (see map 1). The main species planted are as follows: Hoop pine {Araucaria cunninghamii Ait.), Klinki pine {Araucaria hunsteinii K. Schum.), Teak {Tectona grandis Lin.), Kamarere {Eucalyptus deglupta Blume), and Pinus spp. Except for Teak and Pinus, these species are indigenous to the Territory. The areas planted as of May 1967 are given in Table 1.

Stoneflies (Plecoptera) from the Ryukyu Islands in the Bishop Museum, Honolulu

Abstract: The new plecopterans Neopeltoperla ishigakiensis, Amphinemura okinawaensis, Rhopalopsole longicerca and Gibosia linguambita are described from the Ryukyu Islands Through the kindness of Prof Dr J Illies, I was afforded the opportunity to examine material from the Ryukyu Is in the collections of the Bishop Museum, Hawaii The ma­ terial consists of 13 species in 7 genera belonging to Peltoperlidae , Nemouridae, Leuctridae and Perlidae Some of the species appear to be new The material was collected by C M Yoshimoto and J C Harrell of the Bishop Museum during the Scientific Cooperation Program of the United States and Japan2 Some of the species are widely distributed else­ where in Japan Hitherto, the only reports in the stonefly fauna of the Ryukyu Is are those of Ueno (1938) and Kawai (1964) The species found are listed below Inthe majority of cases this is the first record of occurrence of these species in the Ryukyu Is All type materi­ al is deposited in Bishop Museum, Hawaii I wish to express my sincere thanks to Prof Dr Joachim Illies, of the Limnologische FluBstation des Max-Planck Instituts fiir Limnologie for his kindness in placing this interesting material at my disposal It is a pleasure to acknowledge Dr W D Williams, for his kind help in reading and correcting my manuscript PELTOPERLIDAE

Stoneflies (Plecoptera) from Taiwan in the Bishop Museum, Honolulu

Abstract: A new species, Nemoura bispinosa and some new plecopteran records are presented for Taiwan. This article is based upon the stonefly collection accumulated by members of the Bishop Museum under the Scientific Cooperation Program of the United States and Japan. It consists of 40 specimens, belonging to 9 species, of which one is new. They fall into 5 genera belonging to the families Nemouridae Leuctridae and Perlidae. For some, the specific identifications remain in question. The type specimen is in the Bishop Museum (BISHOP). The stonefly fauna of Taiwan (Formosa) has already been reported by the following authors: Klapalek (1912, 1913, 1923), Okamoto (1912, 1922), Ueno (1928, 1929) and Banks (1937). My grateful thanks are due to Prof. Dr Joachim Illies, of the Limnologische Flu/3station des Max-Planck Instituts fiir Limnologie who kindly placed this material at my disposal. I am also indebted to Mr P. Zwick who gave me useful advice concerning the internal structure of the genus Schistoperla. It is a pleasure to thank Dr W. D. Williams for his kind help in reading and correcting this manuscript.
