John Gould, Esq., F.R.S., V.P., in the Chair. Mr. Edwin Ward sent for exhibition the orieinal leg-bones of Dinornis maxinzus, described and figured by Protessor Owen in the Society's ' 'I'raiiJactioiis ' (vol. vi. p. 497, pls. Ixxxix., xc.), belongiirg to Col. Michael. The following papers were read :- 1. On the Spiders of St. I-Iclcnn. 13y the Rev. 0. P. CA~IIBILIUOE,M.lL, C.M.Z.S. [Receired February 1, 1873.1 (Plate XXIV.) In a former paper (Proc. Zool. SOC. ;8G9, pp. 531-544, 111. alii.) twenty species of Spiders were recorded aid described from a collec!iuu reccived from Mr. Melliss, by whom they were captured in the Island of St. IIelena. Since then I have received from the hame geutlcman two other collections, in which, iu additiou to most of the species before recorded, I have found twenty-three others : amoug these, eleven appear to be undesrribed, while, of the re- mainder, five are indigenous to Great Britain, Segestria senoculata, Teyenuria civilis, Scytodes thoracica, Therirlioia tepidariorum, aud Linyphza leprosa; two have been also received from Ceylon and India, Yholcus distinctus and Artenza convexa ; two are European, hqyrodes epeirm and Xysficus yrainmicus ; and two are Egyptian, Lutrodectus erebus and Tetragnatha pelusia. The European stamp observed upon in regard to the Spiders of the former collection is thus eynally marked in those now recorded and described, three only of those already described belonging to species not hithejto recorded as European. According to the present and former papers, the known Spiders of St. Helena thus number forty species, a number which will, I doubt not, be greatly added to when a closer and more extended search shall have been made. I understand that Mr. Melliss has ceased to reside in St. Helena, so there is no more chance of further discoveries in hrachnida from his exertions ; but for what he has done, and so kindly placed within my reach as materials for the present ancl former papers, I desire now to return him my very heartiest thauks.

Immature female, length 22 lines. The whole of the fore part of this Spider is of a yellow colour. The cephalothorax, which is of the ordinary form of the genus, has the upper part clothed pretty thickly with coarse and rather adpressed dark brown hairs, giving a darkish hue to that portion. The eyes are rather large, but in the usual position, seated upon a strongish tuberculiform transverse oval eminence, a little way behi*ld the fore margin of the clypeus, The Zegs are moderately long and strong; they do not differ greatly in length ; those of the fourth pair seemed to be slightly longer than those of the first, and the third pair rather the shortest ; they are furnished with blackish-brow11 bristly hairs only, and each tarsus ends with three inconspicuous claws. The palpi are strong, moderately long, similar to the legs in their armature, except that the single terminal claw is stronger than those on the tarsi of the legs. Thefakes are short and weak, but rather projecting forwards. The rnaxille, labium, and sternum present no observable variation from the usual generic type. The abdomen is oval, rounded and bluff behind, where it projects considerably over the site of the spinners; it is of a dull whitish drab-yellow colour, clothed sparingly with coarsish brown hairs, and marked on the hinder half of the upperside with a series of four or five strong and well-defined trans1 erse nngnlated bars or chevrons of 14" 212 REV. 0. P. CAMBRIDGE ON [Mar. 4, a dull rusty reddish colour, the apex of each one (except the foremost) running into the one before it. These bars span the whole width of the upperside of the abdomen, being stronger at the angles than at the extremities. The spinners, six in number, are very short and inconspicuous.

Cephalothorax oval, depressed, and almost devoid of any lateral constriction forwards, the normal grooves arid indentations being nearly obsolete ; it is of a deep blackish-brown eolour, thinly clothed with pale adpressed hairs. The eyes, looked at from above and behind, arc in two transverse nearly parallel rows ; the hind centrals are further from each other than each is from the hind lateral on its side, while those of the foremost row appeared to be as nearly as possible equidistant from each other. The height of the clypeiis is equal to half that of the facial space; all the eyes (except those of the fore centrai pair, which are dark-coloured) are of a drill amber-colour. ‘Ylie legs ale rather long. moderately strong ; their relative length seemed to be 4, 1, 2, 3 ; they are more or less ot a dark greenish black-hrown hue, except the tarsi and metatarsi (of the fourth pair 1573.1 SPIDERS FROM ST. HELENA. 213 the tarsi only), which are pale-coloured ; they are furnished with hairs of various lengths, and a few spines, chiefly on the tibiae and metatarsi of the two hinder pairs. The palpi are short and not very strong : the radial and cubital joints are very nearly of equal length ; perhaps the former is slightly the shortest, mid has its outer extremity contintied in a tapering apophysis, whose extreme point is slightly obtuse and of a deep brown colour, the rest being of a greenish-brown hue ; the length of this apophysis is rather less than that of the joint itself. The digital joint is rather large, of an oval form, exceeding in length that of the radial and cubital joints together ; the palpal organs are neither very prominent nor complex, consisting of several corneous processes, of a red-brown and whitish colour. The falces are moderately long and strong, projecting forwards, and a little proniineut near the base in front. The mamille, labium, and sternum are of the normal character, and (with the fakes) are of a dark yellowish-brown colour. The abdomen is of a narrow, oblong-oval form ; it is of a black colour, with a somewhat silky bottle-greenish reflection in some positions. It is well rlothed with hairs ; and there are four indistinct pale dots, forming nearly a sqnare, near the middle of the upper- side. The spinners are rather long and prominent, those of the inferior pair being the longest and strongest ; they are of a blackish colour, tipped with whitish. The spiracular plates are large and of a dull yellowish-brown colour. A single adult male was comprised in Mr. Mellias’s collection from St. Helena. Genus CLUBIONA. CLUBIONADUBIA.

In the former collections received from Mr. Melliss the female only of this Spider was found; in the last collection there were several males and several females also. In size, colours, and general characters the sexes are similar; but the fakes of the male are Ionger, and each has a strong conically formed sharp teoth on the under edge of its inner side, near the extremity. The palpi are moderately long and not very strong. The humeral joint has three distinct and nearly erect black spines near its fore extremity on the upperside, two near together in a transverse line, the third, which is the longest, is a little way behirid them. The radial and cubital joints are of equal leirgth ; the former has a small, pointed, tapering, dark red-brown, somewhat tooth-like, corneous- looking apophysis in continuatioii ot its outer extremity, and four or five longish, bristly, prominent hairs on its inner side ; the digital joint is small and of an oval form, iiot much, if at all, exceeding in length that of the radial joint.

Yunnan Province, China, is described and illustrated in this paper. Introduction: Two species of the genus Ragadia WESTWOOD, [1851] have been known from the eastern Himalayan regi- on (Bhutan, N.E. India, N. Myanmar, S.E. Tibet, northwesternmost of Yunnan), viz. R. crisilda HEWITSON, 1862 and R. crito DE NICÉVIllE, 1890 (TAlbOT, [1949]; D’ABRERA 1985; HUANG 2000, 2003; SHIZUYA et al. 2005). In this paper, a new species from Dulong-jiang (upper water of Nmai Hka River) Valley, northwesternmost of Yunnan, is described. Therefore, it is the third species of Ragadia WESTWOOD from this region. All specimens, excluding the holotype, in this study, are deposited in SONG-YUN LANG’s collection, Chengdu, Sichuan, China.

  • The Radiation of Satyrini Butterflies (Nymphalidae: Satyrinae): A
    Zoological Journal of the Linnean Society, 2011, 161, 64–87. With 8 figures The radiation of Satyrini butterflies (Nymphalidae: Satyrinae): a challenge for phylogenetic methods CARLOS PEÑA1,2*, SÖREN NYLIN1 and NIKLAS WAHLBERG1,3 1Department of Zoology, Stockholm University, 106 91 Stockholm, Sweden 2Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Av. Arenales 1256, Apartado 14-0434, Lima-14, Peru 3Laboratory of Genetics, Department of Biology, University of Turku, 20014 Turku, Finland Received 24 February 2009; accepted for publication 1 September 2009 We have inferred the most comprehensive phylogenetic hypothesis to date of butterflies in the tribe Satyrini. In order to obtain a hypothesis of relationships, we used maximum parsimony and model-based methods with 4435 bp of DNA sequences from mitochondrial and nuclear genes for 179 taxa (130 genera and eight out-groups). We estimated dates of origin and diversification for major clades, and performed a biogeographic analysis using a dispersal–vicariance framework, in order to infer a scenario of the biogeographical history of the group. We found long-branch taxa that affected the accuracy of all three methods. Moreover, different methods produced incongruent phylogenies. We found that Satyrini appeared around 42 Mya in either the Neotropical or the Eastern Palaearctic, Oriental, and/or Indo-Australian regions, and underwent a quick radiation between 32 and 24 Mya, during which time most of its component subtribes originated. Several factors might have been important for the diversification of Satyrini: the ability to feed on grasses; early habitat shift into open, non-forest habitats; and geographic bridges, which permitted dispersal over marine barriers, enabling the geographic expansions of ancestors to new environ- ments that provided opportunities for geographic differentiation, and diversification.

Revision accepted: 20 August 2015. Abstract. Widhiono I. 2015. Diversity of butterflies in four different forest types in Mount Slamet, Central Java, Indonesia. Biodiversitas 16: 196-204. The study was carried out in four different habitat types (secondary forest, plantation forest, agroforest, and tourist area) on the southern slope of Mount Slamet, Baturaden Forest, Central Java, Indonesia from July 2009 to August 2010. A total of 99 species belonging to eight families showed a dominance of Nymphalidae (30 species) followed by Pieridae (17 species), Lycaenidae (15 species), Papilionidae (13 species), Satyridae (11 species), Danaidae (6 species), Amathusidae (4 species), and Riodinidae (3 species). From the 99 butterflies species found on the southern slope of Mount Slamet, 32 species (30%) were specific to the forest, whereas 63 species (60.6%) were common to all habitats sampled, and the last 10 species (9.4%) were endemics species with one protected species (Troides helena). The present results was showed that butterflies diversity, abundance, and endemism is still relatively high, representing 18% of all butterfly species found in Java and supporting 71.4% endemic species found in Central Java. The plantation forest were contributed the highest diversity and abundance of butterfly species, whereas the agroforest showed the lowest diversity, abundance, and endemism.

  • Supplementary Material
    ELECTRONIC SUPPLEMENTARY MATERIAL Prehistorical Climate Change Increased Diversification of a Group of Butterflies Carlos Peña, Niklas Wahlberg 2. SUPPLEMENTARY METHODS 1. Taxon Sampling. We included 77 representative genera from the satyrine clade sensu( Wahlberg et al., 2003) as represented in Ackery et al. s (1999) classification for Charaxinae and Amathusiini, Lamas (2004) s for Morphini and Brassolini, including all major lineages in Satyrinae found in our previous paper (Peña et al., 2006), and two outgroup genera (Libythea and Danaus). All sequences have been deposited in GenBank. Appendix S1 shows the sampled species in their current taxonomic classification and GenBank accession numbers. 2. DNA isolation. We extracted DNA from two butterfly legs, dried or freshly conserved in 96% alcohol and kept at -80C until DNA extraction. Total DNA was isolated using QIAGEN s DNeasy extraction kit (Hilden, Germany) following the manufacturer s instructions. 3. PCR amplification. For each species, we amplified five nuclear genes and one mitochondrial gene by PCR using published primers (Table S1). Amplification was performed in 20 µL volume PCR reactions: 12.5 µL distilled water, 2.0 µL 10x buffer, 2.0 µL MgCl, 1.0 µL of each primer, 0.4 µL dNTP, 0.1 µL of AmpliTaq Gold polymerase and 1.0 µL of DNA extract. The reaction cycle profile consisted in a denaturation phase at 95C for 5 min, followed by 35 cycles of denaturation at 94C for 30s, annealing at 47 55C (depending on primers) for 30s, 72C for 1 min 30s, and a final extension period of 72C for 10 min. 4.

It is based on a concatenated alignment of the mitochondrial gene COI and up to 11 nuclear gene fragments, using Bayesian inference of phylogeny. To avoid analytical biases that could result from our region-focus sampling, our European tree was grafted upon a global genus- level backbone butterfly phylogeny for analyses. In addition to a consensus tree, we provide the posterior distribution of trees and the fully-concatenated alignment for future analyses.

The present paper describes the immature stages of the Neotropical satyrine butterfly Euptychia mollina (Hübner, [1813]) from the Brazilian Amazon Forest. Eggs were laid singly on the under surface of the fronds of its host plant, Selaginella sp. (Bryophyta: Selaginellaceae). Larvae are solitary in all instars, presenting a color pattern and shape that make them cryptic on its host plant. The pupa is short, smooth and varies from rusty brown to green. Despite the lack of a close phylogenetic relationship, larvae of Euptychia are very similar to those of the paleotropical satyrines Ragadia and Acrophtalmia, suggesting that camouflage is likely to be one of the factors explaining the similarities among them. KEY WORDS. Camouflage, caterpillar, Euptychiina, Lepidoptera. INTRODUCTION prevalence in some habitats, very little is known about their ecology, behavior and natural history.

VANE-WRIGHT 1) & Michael BOPPRÉ 2) 1) Department of Entomology, The Natural History Museum, London, UK 2) Forstzoologisches Institut, Albert-Ludwigs-Universität, Freiburg i. Br., Germany Abstract. The South American nymphalid Bia Hübner, 1819, treated for over 150 years by most lepidopterists as a member of the Satyrinae, has been shown by recent work on early stages and DNA to share characters with the Morph- inae: Brassolini. Examination of the wing patterns and androconial organs of Bia, described in detail for the first time, reveals unusual features otherwise only known from brassolines. In particular, the tufted posterior androconial organ of the hindwing forming palisades is a synapomorphy for Bia and several genera of Brassolini, including Caligo. The ge- nus Bia is formally transferred from the Satyrinae to the Morphinae: Brassolini as the sole member of the subtribe Biina Herrich-Schäffer, 1864, stat. nov., co-ordinate with Brassolina Boisduval, 1836, and Naropina Stichel, 1925.
