In " Spiders of Palestine and Syria," I. c. supra, doubts are expressed as to its generic place. It still appears to m e that it can hardly be included in any hitherto characterized genus, though at present I hesitate to form a new genus for its reception. It is probably nearer to Steatoda than to any other; yet the very different form of the cephalothorax, in both sexes, appears to preclude it from that genus, to which, however, in deference to M . Eugene Simon's opinion, I now provisionally relegate it, in preference to Pachygnatha. Gen. EURYOPIS, Menge. EURYOPIS ACUMINATA. Theridion acuminatum, Luc. Explor. en Alger, p. 268, pl. 17. fig. 10. An adult female was found under a stone near Alexandria. EURYOPIS SCRIPTA. Theridion scriptum, Cambr. P. Z. S. 1872, p. 283. Adult females were found under stones near Alexandria in April 1864. EURYOPIS QUADRIMACULATA, sp. n. This Spider resembles the two foregoing in respect of size, general form, and characters, but may be easily distinguished by a different distribution of colours on the abdomen. This part in the present Spider is of a deep brown-black colour marked with four elongate brownish yellow spots on the upperside, one at the fore and another at the hinder extremity, and another on each side, a little nearer to the fore than to the hinder spot; these lateral spots are the longest, and are placed obliquely, their inner extremities nearly meeting; the underside has a pale dull yellow transverse bar just behind the genital aperture, and another close in front of the spinners, the two being connected, or nearly so, by a longitudinal line of the same hue. The palpi are short, the radial and cubital joints very short, but nearly equal in length ; the digital joint is very large, and the palpal bulb well developed, a strong sinuous red-brown line (indicating, no doubt, the passage of an internal channel) may be seen on the outer side ; and from the fore extremity there projects a strong, pointed dark red-brown corneous process, slightly curved and pointing backwards and a little outwards. An adult male and female were found near Alexandria under stones. Gen. THERIDION, Walck. THERIDION RUFOLINEATUM. Theridion rufolineatum, Luc. Explor. en Alger, p. 260, pl. 16. fig. 10.
