114 SCORPIONS, PEDIPALPI AND SPIDERS COLLECTED BY DR WILLEY 



According to L. Koch's tables of Australian species of Sparassits this new form 

 falls under the heading and alongside of S. nitelinus from Peak Downs, a species which 

 it also somewhat resembles in the form of the vulva. S. actaeon certainly differs, how- 

 ever, in being much larger, differently coloured and in possessing much longer legs. 



Genus. Palystes, L. Koch. 



Palystes ignicomus, L. Koch. 



Palystes ignicomus, L. Koch, Die Arachniden II., p. 701, pi. lx., figs. 2 — 20, 1875. 

 Sarotes vulpinus, O. P. Cambridge, Proc. Zool. Soc. 1877, p. 286. 



Loc. New Britain. 



The specimen of the species described by Dr Koch was collected in New Ireland. 

 The type of vulpinus, which Mr Cambridge has kindly sent to me for examination, 

 was obtained by the Rev. George Brown either in the Duke of York Island or on the 

 adjacent coasts of New Ireland or New Britain. Although this specimen is a not quite 

 adult female, I have no hesitation in regarding it as specifically identical with 

 P. ignicomus, of which Mr Willey obtained some beautifully coloured examples (J", $). 



Genus. Thelcticopis, Karsch. 



Thelcticopis ochracea, sp. n. 



PI. X. Kg. 11. 



Colour : carapace, sternum, and legs a nearly uniform pale castaneous tint, legs 

 paler than carapace, both scantily clothed with greyish white hairs ; abdomen a pale 

 mouse grey with a series of indistinct median spots above and short oblique stripes 

 of the same tint on each side ; mandibles deep brown. 



Carapace about as long as patella and tibia of 4th leg, a little shorter than 

 those of 2nd leg. Mandibles moderately strongly geniculate. Palpi with tarsus apically 

 scopulate, its femur armed apically with 5 spines, patella with 1 anterior and 1 pos- 

 terior spine, tibia with 3 anterior, 1 superior and 2 posterior spines, tarsus with 3 

 anterior (inner) and 3 posterior (outer). 



Legs: 1st, 2nd and 4th nearly equal; femur of 1st armed with 1 or 2 anterior, 

 1 superior and 3 posterior spines, patella unarmed, tibia with 6 pairs of inferior spines, 

 protarsus with 1 pair of inferior spines; 2nd leg, femur with 3, 2, 3 spines, tibia 

 with 5 pairs of inferior spines; 3rd leg, femur with 3, 2, 1 superior spines; tibia, 3 

 pairs of inferior spines, and 1 anterior spine ; 4th leg as in 3rd, but the tibia armed 

 in addition with 2 interior and 2 posterior spines, and the protarsus with 2 pairs 

 of inferior spines, 3 anterior and 3 posterior; tibiae of 1st and 2nd leg very slightly 

 scopulate anteriorly. 



Vulva consisting of a large plate deeply hollowed out, the margin of the exca- 

 vation semicircularly concave in front, produced posteriorly and laterally into a rounded 

 prominence on each side, and ending behind in a pair of narrowed apically rounded 

 processes projecting beyond the hinder border of the median sclerite, which consists 

 of a pah - of smooth shining bosses united posteriorly and ending in a small sub- 

 quadrate prominence.
