Show 746 MR. R. I, POCOCK ON ETHIOPIAN SPIDERS. [June 15, b5. Posterior sternal sigilla remote from the margin; ocular cluster compact; a pair of apical spines on the lower side of the tibiae of all the legs; scopulae narrower ; body and limbs normally hairy ; claws not toothed. a6. Tibia of 1st leg in male with a single spur tipped with two bunches of spines (patella and tibia of 4th leg not longer than those of 1st) Monocentropus, nov. 48. Tibia of 1st leg in male unarmed (patella and tibia of 4th leg longer than those of 1st) Anoploscelus, nov. b3. Thoracic fovea small, linear, crescentically pro-curved. a1. Tibiae and protarsi of legs, especially those of the 3rd and 4th pairs, strongly spined; scopula of 4th tarsus divided by a distinct band of setae; claws toothed; posterior sternal sigilla submarginal; male with a pair of tibial spurs Selenogyrus, nov. b1. Tibiae and protarsi of legs, with the exception of a few spines at the apices below, unspined; tarsal scopula of 4th leg (except in Eumenophorus) undivided ; claws not toothed; posterior sternal sigilla remote from the margin ; male without tibial spur (? in Eumenophorus). a8. Protarsal scopula on 4th leg almost absent; tarsal scopula of 4th divided by a broad band of setae Eumenophorus, nov. bs. Protarsal scopula of 4th leg distinct and entire ; tarsal scopula of 4th thick and undivided. a3. Protarsal scopula of 4th covering only tbe distal third of the segment; (palp of male extending nearly as far as the apex of the tibia of the 1 st leg) Phoney usa, Karsch. 69. Protarsal scopula of 4th extending almost to the base of the segment; (palp of male extending only just past the end of the patella of the 1st leg) Hysterocrates, Simon. The following genera are unknown to me :- Pelinobius, Karsch (Jahrb. Hamb. Wissen. Anst. ii. p. 135,1885), was based upon a male specimen named muticus, from Masailand, which, according to Karsch, differs from helanclana ( 2 ), the type of Phoneyusa, in wanting the apical spines upon the inferior surface of the tibia of the 4th leg. Simon, however, when comparing Pelinobius with Harpaxotheria (= Phoneyusa), states as differential characters of the former, firstly, that the posterior median eye is nearer the anterior median eye than it is to the posterior lateral, and secondly, that the protarsal scopula of the 4th leg is narrower than the segment. But it is not stated that these observations are based upon the type-species. Anyhow, the genus, if distinct from Phoneyusa, will fall under the section a9 of the above table.
