ON FALKLAND LSLANB SPIDERS. 37 2. Some Falkland Island Spiders. By H. R. Hogg, M.A., F.Z.S. [Ueceived October 8, 1912 : Read November 12, 1912.] (Plates I. & II.*) Index. Page Sj'steinatic : — • Araneus vallentini, sp. n 37 Araneus glohiger, sp. u 39 Tetragnatha insulata, sp. n 41 Philisca colulata, sp. n 42 Emmenommafalklatidica, sp. ii 45 FetiHciis signatiis, sp. n 46 Sadocus vallentini, sp. n 48 The small collection of spiders from the Falkland Islands described below was brought to this country by Mr. Rupert Yallentin, who has been good enough to afford me the oppor-tunity of examining them. Connected generically with Patagonia and the Magellanic Region, they are all apparently new species. Gathered as they have been over a period of two years, they comprise only six species of spiders and one Opilio, of Sorensen's genus Sadocus, with a fair number of specimens of some of the species. Three of these are Argiopidse which are easily conveyed by the wind, and supply no argument for a former land connection between these islands and the mainland of America. Family Argiopid.e. Group Argiope.e. Genus Araneus Olerck. Araneus vallentini, sp. n. (PL I. figs. 3-3 e.) The colour as seen in specimens taken from spirit is as follows : — Oephalothorax pale yellow-brown with longitudinal streaks of long white hair, rather bare on the sides but a pale marginal streak all round. Mandibles pale yellow-brown at the base, dark brown at the apex. The fangs are dark brown at the base, dingy yellow-brown at the points. * For explanation of the Plates see p. 50.
