Measurements in millimetres. Total length 19, length of carapace 10, of 1st leg 22, 

 2nd leg 21, 3rd leg 28, 4th leg 28. 

 Loc. New Britain. 



With the eyes of the anterior row a little narrower than those of the median, 

 the abdomen uniformly yellow below, two spines on the upper side of the tibia of 

 the 3rd and 4th legs, the patellae of the 1st and 2nd pairs without spines, the 

 anterior median eyes larger than the anterior lateral, the protarsus of the 4th leg 

 shorter than the patella and tibia of this limb and the carapace ornamented with 

 median and lateral bands, Lycosa willeyi falls alongside of L. pulvere-sparsa of L. Koch 

 (Die Arachniden Austral. II., pp. 895 and 941, PI. LXXXL, Fig. 6, 1877 and 1878) 

 from Rockhampton, but certainly differs from it, at least in the form of the vulva, 

 the excavation of the epigynal plate being much broader, the cross-bar of the median 

 piece much longer, etc.

 cephalothorax and legs (in alcohol) blackish, with a broad reddish line in the dorsal 

 middle line; sternum and coxae bright yellowish red. 



Carapace higher behind than in front, a nearly even slope from the posterior to 

 the anterior edge of the upper surface ; a little shorter than patella and tibia of 

 1st leg and a little longer than those of 2nd, a little longer than 4th protarsus. 

 Eyes : ocular quadrangle wider than long, narrower in front than behind ; anterior 

 median eyes smaller than posterior median and closer together, space between them 

 about equal to their radius ; eyes of second row a little procurved, the lower edge of 

 the laterals slightly below the level of the lower margin of the medians ; the anterior 

 laterals oval, separated from posterior medians by a space about equalling their long 

 diameter; clypeus short, less than radius of anterior centrals. 



Legs: femur of 1st armed with 11 spines, arranged in rows approximately 4,3, 4; 

 patella, spines 1, 1; tibia armed with 5 pairs below, 2 in front, 3 above, and 2 behind : 

 protarsus armed with 12 spines 3, 3, 3, 3 ; with or without an additional median spine 

 above; 2nd leg armed apparently as the 1st; 3rd leg, femur with about 11 spines; 

 tibia with 3 pairs below, 2 spines in front, 3 above, and 2 behind ; protarsus with 

 3 pairs below, 3 spines in front, 3 behind, with 1 extra above and 1 at the apex ;
