Show 1901.] TRAP-DOOR SPIDERS. 213 setae below; protarsus with many strong spines, tarsus with a few apical spines ; 4th leg with tibia scarcely spined, protarsus with a few setiform spines ; tarsus also only armed beneath with setiform spines. Measurements in millimetres.-Total length 15 ; carapace 6 ; 1st leg 12, 4th leg 16. Hab. China; D a Lan San, 60 miles uphill from Ningpo (P. W. Bassett-Smith, Surgeon R.N.). This species apparently falls into section D of the species of the genus as divided by Simon. It is remarkable for its low head, strongly procurved anterior line of eyes, and strongly spined legs. The genus Nemesia has hitherto not been obtained outside the limits of the Mediterranean Eegion. Its occurrence in China, therefore, is peculiarly interesting. Family DIPIUBIDI. Genus MACROTHELE Ausserer. MACROTHELE PALPATOR, sp. n. (Plate XXI. fig. 4.) 5. Uniformly coloured like M. fuliginea. Eyes not very different from those of M. fuliginea. Carapace a little longer than patella and tibia of 1st leg, equal to those of 4th and to protarsus and half the tarsus of the 4th. Palp with tarsus about as long as the patella and tibia, lightly expanded at the base, armed with 3 external, 1 inferior distal, and 3 or more internal and distal spines. Legs 4, 1, 2 and 3 in length : 1st with 3 inferior apical tibial spines, 4 - 4 - 3 inferior protarsal and about 7 - 7 lateral tarsal spines ; 2nd leg spined much like the 1st; 3rd and 4th with tibiae, protarsi, and tarsi more numerously and less regularly spined, and also with few spines on the patellae. o*. Smaller than $ . Carapace jet-black, as long as patella and tibia of 1st leg. Tibia of 1st leg armed beneath with 3 long spines in addition to an apical pair; tibia of 2nd leg armed with 5 long spines below ; protarsus of 2nd lightly bowed at base and only armed with about 4 inferior spines, protarsus of 1st armed with three rows of long strong spines. Palp with tibia armed above with a band of about 12 short spines, this segment long, lightly convex above, swollen below at the base ; tarsus short, truncate, about one-fourth as long as the tibia; palpal organ enormously long, about as long as the patella and tibia of the palp and as the width of the carapace, the spine broad at the base, gradually narrowing and very fine and filiform at the apex, with a lightly sinuous curvature. Measurements in millimetres.- $ . Total length 18 ; carapace 8 ; 1st leg 21, 2nd leg 20, 3rd leg 20, 4th leg 25. 3 (type). Total length 12; carapace 6 ; 1st leg 16, 2nd leg 16, 3rd leg 15, 4th leg 20. Loc. China : Hong Kong (J. C. Boivring) ; D a Lan San, 60 miles PROC. ZOOL. Soc-1901, VOL. I. No. XV. 15 |
