PICKARD CAMBRIDGE ON [June 16 Coxa of pedipcdp three times its breadth, not produced at anterior angle ; bearing on the inner basal angle three sharp black cusps set in a curving row. Legs 4, 1, 2, 3, clothed with fine rufous hairs, black curving bristles, and black spines. Tarsi i. and ii. with two claws and a claw-tuft; claw armed with a minute denticle rather before the middle, beneath ; scopulate. Tarsi iii. and iv. with two claws and a claw-tuft, the claws bearing no denticle; very slightly clothed beneath with scattered scopuliform hairs. Protarsi i. and ii. with slight scopula at apex and two stout spines, one apical, the other basal, beneath ; iii. and iv. with numerous spines. Tibia i. bearing at its apex on the inner side, beneath, a pair of stout curved spines set in juxtaposition to each other, with five ordinary spines, 2 - 1 - 3 beneath, and one on the inner side. Tibia iii. and iv. with numerous spines. Femora of all four pairs with five or six spines above. Pedipalp. Femur with a few spines at apex above. Tibia fringed on either side beneath with long hair, and six spines on the inner side, two on the outer. Tarsus short, half the length of tibia. Bulb short, pyril'orm, transverse, its stylum very short, curved, directed outwards and backwards. Comparative measurements In millimetres.- o* . Carap. 6-5 long., 5-5 lat. Abd. 5-5 long., 3-5 lat. Ceph. area 4 long. Stern. 3-25 long., 2-5 lat. Coxa of pedipalp 2-5 long., 1-25 lat. Pedes, long. i. 25-ii. 23-iii. 20-iv. 30. Artl. i. long. 3-25-1-25-6-5-3- 5-5_4_3. Artl. iv. long. 3-1-7-5-2-6-8-5-2-5. Postr. mam. long. 3*5 ; artl. 1*5-1--5. Antr. mam. -75. M y attention was called to a fine specimen, an adult male, of this species by Mr. E. E. Austen when collecting in the neighbourhood of Manaos, Amazonas, in February 1896, and I have great pleasure in connecting his name with the species. The generic characters which distinguish Homceoplacis from Barychelus are well marked. Cephalic fovea procurved; rastellum at apex of mandible consisting of five separate teeth ; coxa of pedipalp armed near the base with only a few (3-4) small cusps ; ocular tumulus narrower in front. M . Simon apparently does not know the male of the species he has made the type of his genus, so that no mention is made of the spines at the apex of the tibiae of the first pair of legs. Species described.-H. pentodon, Sim. op. cit. p. 275. It is possible that the Spider described above may be the male of the one described by Simon : but it is not easy to identify a specimen of this sex from a description of the female. He says of it-" Parte cephalica vittis duabus;" of H. austeni one would rather say-"Parte cephalica lineis tribus;" and again he says: " parte thoracica lineis radiantibus, lineaque marginali obscuriori-bus notatis " ; whereas in m y specimen there are no radiating lines and no marginal dark line. |
