A HISTORY OF STAFFORDSHIRE ARACHNIDA Spiders, etc. Very few species of spiders, eighty-two in all, have been collected in the county of Staffordshire, and the greater number of these were taken in the neighbourhood of Handsworth by Mr. F. P. Smith, while the rest were taken by myself near Cannock. ARANE^ ARACHNOMOR PHM DYSDERIDjE Spiders with six eyes and two pairs of stigmatic openings, situated close together on the genital rima ; the anterior pair communicating with lung books, the posterior with tracheal tubes. Tarsal claws, two in Dysdera, three in Harpactes and Segestria. 1. Dysdera cambridgii, Thorell. Cannock. Not uncommon under stones and bark of trees, where it lurks within a tubular retreat. The spider is easily recognizable by its elon- gate form, orange legs, dark mahogany cara- pace and pale clay-yellow abdomen. The palpal bulb of the male has no cross-piece at the apex. The spider is also known as D. erytbryna, Blackwall. T-, , ,-, T V 2. Dysdera crocota, C. L. Koch. Handsworth (F.P.S.). Larger than the last species, with a deep orange-pink carapace, orange legs, and abdo- men with a delicate rosy-pink flush. The palpal bulb of the male has a cross-piece at the apex. This spider is also known as D. rubtcunda, Blackwall. 3. Segestria senocu/ata (Linnaeus). Handsworth (F.P.S.). Not common . under bark of trees> in the crev ices of loose stone walls and amongst d etac h e d rocks. Recognizable by its linear f orm and the black diamond-shaped blotches on the dorsal surface of the abdomen. 4. Oonops pulcher, Templeton. Handsworth (F.P.S.). Rare ; a very small linear brick-red spider. DRASSIDjE Spiders with eight eyes, situated in two transverse rows. The tracheal openings lie just in front of the spinners. The tarsal claws are two in number, the anterior pair of spinners are set wide apart at the base, and the maxillae are more or less impressed across the middle. 5. Drassodes lapidosus (Walckenaer). Cannock. Very common under stones. as Drassus lapidicolens. Also known CLUBIONID^E Spiders with eight eyes, situated in two transverse rows. The tracheal openings lie immediately in front of the spinners. The tarsal claws are two in number, but the anterior pair of spinners are set close together at the base ; the maxillae are convex and not impressed across the middle. 9. Clubiona corticalis, Walckenaer. Handsworth (F.P.S.). 10 . Clubiona trivia/is, L. Koch. Cannock. 6. Clubiona pallidula (Clerck). Handsworth (F.P.S.). 7. Clubiona terrestris, Westring. Handsworth (F.P.S.). 8. Clubiona compta, C. L. Koch. Handsworth (F.P.S.). The spiders of this family resemble those of the Clubionidte in most respects, except that the tracheal stigmatic openings beneath the abdomen are situated about midway between the 120
