SPIDERS ARACHNIDA Spiders, etc. Scarcely any records of either spiders, harvestmen or false scorpions have been made for the county of Warwickshire. The following list is drawn up from a collection made by the Rev. J. Harvey Bloom at Whitchurch near Stratford-on-Avon. ARANE^E ARACHNOMORPHM DYSDERID^: 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. 2. Dysdera crocota, C. L. Koch. Stratford-on-Avon (J.H.B.) 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. rubicunda, Blackwall. I. Dysdera cambridgii, Thorell. Stratford-on-Avon (J.H.B.) Not uncommon under stones and bark ot 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. erythryna, Blackwall. DRASSID^ 3. Prosthesima nigrita (Fabricius) Whitchurch (J.H.B.) 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. 4. Clubitna stagnatilis, Kulczynski. Stratford-on-Avon (J.H.B.) 5. Clubiona terrestris, Westring. Stratford-on-Avon (J.H.B.) 6. Clubiona pallidula (Clerck) Stratford-on-Avon, Warwick (J.H.B.) 7. Clubiona phragmitis, C. L. Koch. Stratford-on-Avon, Warwick (J.H.B.) 8. Clubiona diversa, O.P.-Cambridge. Whitchurch (J.H.B.) The spiders of this family resemble those of the Clubionidte in most respects, except that the trachael stigmatic openings beneath the abdomen are situated about midway between the genital rima and the spinners, and not, as in the last family, immediately in front of the spinners. One species only is indigenous to Great Britain, and is very common amongst the foliage of trees in May and June. 9. Anypbeena accentuata (Walckenaer) Stratford-on-Avon (J.H.B.) Spiders with eight eyes, situated in two transverse rows, two tarsal claws and anterior spinners close together at their base. Maxillae not impressed. The crab-like shape and side- 167
