214 ON NEW TRAP-DOOR SPIDERS. [Mar. 5, 



uphill from Ningpo (P. W. Bassetf-SmitJi, Esq., Surgeon B.N. ; 

 d (type), 5 ). , , . . 



Distinguishable from the Javan M. fuhginea Simon (Ann. 

 Soc. Ent. Prance, 1891, p. 306), which it resembles in colour, 

 in having 3 rows of spines instead of 2 rows on the under- 

 side of the protarsi of 1st and 2nd legs, as well as in the greater 

 length of the tarsus of the palp. The British Museum has 

 specimens of M.fuliginea from Ijigouibong in Java {E. W. Anclrexvs) 

 and from Singapore {H. N. Ridley). 



Mackothele holsxi, sp. n. (Plate XXI. fig. 5.) 



S . Coloured like the Burmese and Javan M. maculata Thorell 

 (Ann. Mus. Genova, xxviii. p. 409, 1890) and the Penang 31. scg- 

 mentata Simon (Ann. Soc. Ent. Er. Ixi. p. 284) ; that is to say, with 

 the abdomen ornamented above with about 5 pairs of oblique 

 transverse pale bands and some pale spots on a darker ground. 

 Eyes practically as in M. fuliginea and M. palpator. Carapace as 

 long as patella and tibia of 1st leg, the fovea having the form 

 rather of a median transverse pit than of a transverse sulcus. 

 Legs : femur of ] st spined internally, patella with about 4 spines ; 

 tibia armed internally and below with about 28 strong spines 

 arranged in irregular series, protarsus with 10 spines in two rows, 

 tarsus with 5 small spines in two rows ; tibia of 2nd leg with 2 

 internal and 5 inferior, of which 3 are apical, protarsus with 4 — 2 

 spines ; tibia of 3rd and 4th with 2 apical spines below. Palp 

 shorter than in M. palpator, the tibia about three times as long as 

 the tarsus, armed above with two bands of spines and 1 long 

 inferior external spine ; palpal organ about as long as the tibia 

 and half the width of the carapace, the spine with its basal third 

 thick, its apical two-thirds filiform, lightly sinuous. 



In two sub-adult females the tarsus of the palp is only as long 

 as the tibia, and the tibiae and protarsi of the anterior legs are 

 spined as in M. fuliginea. 



Measurements in millimetres. — c? • Total length 14 ; carapace 7 ; 

 1st leg 19, 4th leg 22. 



Hah. Laki-ku-li, Central Formosa (P. A. Hoist). 



The males of the two species of MacrotJiele here described may 

 be compared as follows : — 



a. Palpal organ at least as long as tibia and patella of palp and as 



width of carapace ; tibia of palp about four times as long as the 

 tarsus, armed above with a single band of close-set spines ; tibia 

 of ] st leg armed with about 7 spines below and internally, 

 patella and tibia scarcely spined ; tibia of 2nd leg with 5 long 

 and strong close-set spines, protarsus slightly curved at base ; 

 tibia of 3rd and 4th armed with many strong spines below ... M.palpaior. 



b. Palpal organ only as long as tibia of palp and as half the width 



of the carapace ; tibia of palp with two bands of spines above, 

 only about three times as long as the tarsus ; tibia of 1st 

 leg armed with about 28 spines, patella and femur spined 

 internally ; tibia of 2nd armed with scattered spines below ; 

 protarsus unmodified ; tibia of 3rd and 4th with a pair of 

 apical spines below M. holsti.
