Show 1897.] MR. R. I. POCOCK ON ETHIOPIAN SPIDERS. 761 genus was primarily based. And since the type of Harpaxotherla, namely antilope, is admitted by Mons. Simon (see Hist. Nat. Araignees, i. p. 154, 1892) to be congeneric with helandana, it is clear that Harpaxotherla is a synonym of Phoneyusa. PHONEYUSA GREGORII, sp. n. (Plate XLIII. figs. 6-6 a.) 3.-Colour deep brown; the carapace and legs clothed above with bright reddish-brown hairs ; hairs on the lower side of the tibia of the palp long and numerous ; a long scopula of feathery hairs on the outer side of the femur of the palp ; upperside of abdomen furnished with long bristles. Carapace distinctly shorter than the patella and tibia of the 1st and 4th legs, only a little longer than the 4th protarsus; ocular tubercle moderately convex, about one-third wider than long; eyes of anterior line slightly procurved, the median a little larger than the lateral, separated by a space a little less than their diameter; posterior lateral smaller than the anterior lateral; the posterior median still smaller, closer to the posterior lateral than to the anterior median. Legs long, 4, 1, 2, 3; patella and tibia of 4th and 1st almost equal; protarsus of 4th just equal to patella and tibia of 2nd ; femur of the 3rd incrassate, nearly as thick as high* much thicker and higher than its patella; scopulae all complete; protarsi of 1st and 2nd scopulate to base, of 3rd wdth more than its distal half covered, of 4th with quite its distal third covered; protarsi with at least one spine at the apex ; tibiae of 3rd and 4th with a pair of spines, of 2nd with 3 spines, two being external, of 1st with two external spines and a cluster of three on the inner side. Palp long; patella, tibia, and tarsus as long as the carapace; unspined; spine of palpal organ distally attenuate, curved forwards, then outwards, wdth a strong basal keel on its outer side. Measurements In millimetres. Total length 41 ; length of carapace 21-5, width 18 ; length of palpus 34-5, of 1st leg 63, of 2nd leg 58'5, of 3rd leg 56, of 4th leg 73 ; patella and tibia of 1st 23*8, of 4th 24 ; of 4th protarsus 20. Loc. Kilungu, Iveti Mountains (Masailand). A single male example obtained by Dr. J. AV. Gregory. The type of this species is much larger than those of graclllpes and ectypa mentioned below, which are also males, the carapace in these measuring il and 12 m m . respectively. In the former, moreover, the 4th leg is more than four times as long as the carapace, and there are 8-10 spines on the lower side of the 1st tibia. P. ectypa, on the contrary, would seem to resemble this new form in most particulars, so far as can be judged from the description; but apart from its much smaller size there is no mention of the band of scopular hairs on the outer side of the femur of the palpl. 1 This character m a y be of generic importance, since it is found in all the species of Hysterocrates known to me, as well as in Acentrocnemis. |
