Show 736 MR. R. I. POCOCK ON ETHIOPIAN SPIDERS. [June 15, of 3rd and 4th divided by a complete band of setae : protarsi of these legs wdth only faint traces of scopulae at their distal ends; tlblce of 1st and 2nd with 1, 1, 2 setiform spines below, tibia of 3rd wdth 2, 2, 2 setiform spines below and in addition 2 strong spines behind, 2 above and 3 in front; patella of 1st and 2nd leg unarmed, of 3rd with 2 spines in front and 2 behind; patella of 4th with 1 spine behind ; protarsus of 1st and 2nd with 2 spines (3 on 2nd protarsus) beneath amongst the scopular hairs and 1 at apex ; protarsus of 3rd armed with 15 spines arranged in rows of 3 each ; protarsus of 4th with a large number of irregularly arranged spines. Each claw with two rows of strong teeth. Palp : femur armed internally at apex with one spine, bristly, patella unspined; tibia armed below with about 7 spines, of which two pairs are at the apex; tarsus scopulate throughout below scantily posteriorly, with one external basal spine. Posterior spinners more than half the length of the carapace, the apical segment the longest. Measurements In millimetres. Total length 16 ; length of carapace 7-5, width 5-5 ; length of 1st leg 18, of 2nd 16-5, of 3rd 14'5, of 4th 20, of posterior spinner 4-3. Loc. Durban (H. A. Spencer). A single female example. The only other known S. African species of this genus is B. capensis from the Cape of Good Hope, described by Ausserer (Verh. z.-b. Wien, 1871, p. 175). The new species from Durban appears to differ from capensis, according to Ausserer's description, in having the 4th tarsus scopulate, in the colouring of its legs, the recurved thoracic fovea, &c. Genus HETEROTHELE, Karsch, SB. Nat. Fr. Berlin, 1879, p. 64. This genus was omitted by Simon from his classification of the Dlplurlnce as " invlsum et incertce sedls." The genus, however, is highly important, inasmuch as it partakes of the characters of Simon's Dlplurece and Macrothelece, and yet differs from both as well as from all the other genera of the family in possessing ungual tufts. The tarsi of all the legs are weakly scopulate, the scopulae being divided by a line of setae ; scopular hairs are also visible at the apices of the protarsi. The 3rd claw is distinct except on 1st leg, where it seems to be absent, but there is a very distinct ungual tuft on each side of it as Karsch states. The superior claws are furnished with a single row of teeth; the tibiae and protarsi of the legs are strongly spined; the tarsi are straight, shorter than the protarsi and not flexible. The tibia of the 1st leg in the male is not spurred, and the spine of the palpal organ is long and slender. The thoracic fovea is subcircular; the ocular tubercle wide, the anterior line of eyes almost straight. The anterior spinners are adjacent, the distance between them |
