B. Eyes of front row differing slightly or not at all 

 in relative distance. The side-eyes generally not 

 smaller than the median. 

 Ji. Median eye-space clearly longer than broad ... Pediana E. Sim. (2) 

 h'. Median eye-space not longer than broad. 



h'^. Cephalothorax clearly convex, generally set 

 on to the abdomen at an angle so that the 

 anterior portion is higher than the rear. 

 Clypeus at least as broad as the front middle 



eyes N'eosparassns, nov. gen. (1) 



h*. Cephalothorax flat on the top or only slightly 

 convex, set on to the abdomen so that the 

 front and rear portions are about level. 

 Clypeus generally not so wide as front 

 middle eyes. 



b^. Cephalothorax longer than broad Zachria. (3) 



b^. Cephalothorax not longer than broad. 

 b'^. Inner side of mandibles and outer side 

 of maxillee covered with thick mat of 



hairs, many of which are bifid Typostola E. Sim. (5) 



b^. Having no special mat, but long hairs 

 thinly covering the whole surface of the 

 mandiblesand maxillae (except J. ■u«s^(z). Isopeda Jj. 'Koch. (4) 



Genus Neosparassus, nov. 



Heteropoda L. Koch, Ar. Austr. 1875 (non Latr,). 



Heteropoda F. Karsch, Zeitschr. f. ges. ISTaturwiss. 1878, p. 809, 

 ad partem H. patellata. 



Sparassus T. Thorell, Ragni Austro-Malesi, 1881, notes pp. 255, 

 274 (at least in part). 



Sparassus E. Simon, Rev. Spar. (Actes Linn. Soc. Bordeaux, 

 1880) ; id. Hist. Nat. des Ar. vol. ii. p. 46 (1897) (in part). 



Of the genera included in the group Belenece the members of 

 this genus come nearest to Heteropoda Latr., with which they 

 were included by L. Koch. Neither the cephalothorax nor 

 abdomen show any signs of compression ; the coloi'ation and 

 patterns are often vividly bright and varied, and the patterns of 

 the female vulva are of rather diversified form, though roughly a 

 sunken area, more or less divided longitudinally by a wedge-shaped 

 ridge, enclosed in a chitinous frame. The male palps, however, in 

 all the species of which I have been able to obtain specimens, are 

 of the spiral conductor and flagellum type, more or less elaborated 

 and varying from two or three spirals in N. calligaster Thor. and 

 N. diana L. K., to nine or ten in iV. salacius L. K. 



The cepihalothorax is generally high, the highest point of the 

 curve being between the eye-space and middle of cephalothorax, 

 thence sloping posteriorly, and in this differs from Heteropoda 

 Latr., where Ii. Koch placed the species. Owing, however, to the 

 angle at which the cephalothorax is often set on to the abdomen, 

 the front part appears more prominent than it really is with 

 respect to the plane of its legs. 



Besides the palpal difference from the type species of Sparassus, 

 they differ in having legs in order 2 14 3, instead of 4th longer
