516 MR. H. R. HOGG ON SPIDERS 



This species would seem to be rather close to Z. julia Thor. 

 (1. c. p. 650), which it resembles apparently in the pattern of 

 brilliant scales on a black ground and the form of the epigyne, 

 but differs from it in the much more even lengths of the legs, 

 the third pair in Z. julia exceeding the first and fourth by 2^ and 

 3 1 millimetres respectively, and being also dai'ker in colouring. 



It is much paler in colour, larger, and the legs i. and iii. 

 are nearer the same length, than in Mr. Pocock's Z. variatus 

 (Willey, New Britain, etc., vol. i. 1899, p. 117). It differs also 

 from Z. cVurvillei (Walck.) in the much brighter colouring and 

 absence of rings on the legs, while the pattern of the epigyne 

 differs from that drawn by Yon Keyserling (Die Arach. Aust. 

 pi. cxx. fig. 4 d). 



Males. In most respects these agree so closely Avith the 

 females described above and are represented by so nearly the 

 same number of specimens in the present collection, that it is 

 difiicult to avoid the conclusion that they are males of the same 

 species. The chief difference is that the front pair of legs are 

 much longer than the others, a fact which does away with one of 

 the characteristics of the genus, in which the third pair of legs 

 are said to be much longer than the others. Were it not, how- 

 ever, for the special enlargement of the first pair, the third would 

 be the longest. 



The clypeus is not quite so broad as the diameter of the fi'ont 

 median eyes, the rear row is as broad as the front row. The 

 eye-space slopes forward, and from the hinder row the thoracic 

 part slopes steeply to the rear mai'gin. 



The mandibles are flatter than in the female, both the outer 

 and inner sides being strongly corrugated transversely. The 

 tooth on the upper margin is of moderate size ; the inner margin 

 of the falx-sheath is cut away to about one-third of the length of 

 the outer margin and exists only for a short distance near the 

 base. The lip is as broad as long, rounded in front, hollowed 

 out on either side of the base, and transversely corrugated. 

 The sternum is three-fourths as wide as it is long, truncated in 

 front, and the coxas are as far apart as the greatest width of 

 the lip. The male palp has a flagellum in about three spirals at 

 the anterior end of a plain oval bulb. 



The front pair of legs is strongly fimbriated on the under side 

 of the patellar, tibial, and metatarsal joints. The cephalothorax 

 and abdomen are black-brown, with a pattern of opalescent pearly 

 scales. 



Under metatarsus i. are two pairs of stout spines, but none at 

 the side. Three pairs under tibia i. One spine each on patellae 

 iii. and iv., and a bunch at the anterior end of metatarsi iii. 

 and iv.
