distinctly shorter than patella and tibia of fourth ; width of 

 carapace less than first tibia. Eyes of anterior line slightly 

 procurved; posterior medians about a diameter apart, ante- 

 rior medians about two diameters ; distance between median 

 and lateral of anterior line more than twice as great as that 

 between the medians. 



Mandibles basally prominent ; fang-groove armed below 

 with 4 teeth in front, 3 behind. 



Legs longish and slender, spiny. 



Abdomen at least as wide as long, voluminous, without 

 shoulder-points, widely rounded in front, shortly ovate behind. 



Vulva differing from that of A. Spenceri and A. Marskalli 

 in that, viewed from the side, the scape is seen to rise from 

 the anterior end of the basal pillar, the posterior part of which 

 is separated from the scape by a deep notch, smaller, but of 

 the same nature as that which obtains in rujipalpis. 



Measurements in millimetres. — Total length l4 - 5; length of 

 carapace 4 - 5 ; length and width of abdomen 9*5 ; length of 

 first leg 15, of fourth 14. 



Loc. Estcourt, 4000 feet (G. A. K. Marshall). 



The females of the species of Araneus here mentioned may 

 be distinguished as follows : — 



Female. 



a. Basal portion of vulva expanded at the sides and 

 projecting laterally beyond the lateral margins of 

 the scape ; Bcape broad at the base, narrower ] o— 

 terioriy, Its basal half horny and hairy, its distal 

 half soft and membranous, bent upon itself and 

 folded within the vestibule of the vulva in such a 

 way that the somewhat heart-shaped expanded 

 terminal portion is in contact with the hairy por- 

 tion of the vulva. (Eyes of anterior line slightly 

 recurved; carapace much longer than tibia of Drat 



leg.) ct/rtost apus, sp. a. 



//. Ba>al (vestibular j portion of vulva not expanded 

 laterally beyond the side-margins of the scape, 

 forming a horny pillar ; scape entirely horny and 

 not folded or bent upon it-elf. 

 a When viewed from tin- side the scape is seen to 

 be much narrower than the distal end of the 

 basal portion, and to rise from its anterior 

 ed<, r e, being separated by a deep notch or nar- 

 row space from the posterior edge of the distal 

 end of the basal portion. 

 a*. Eyes of anterior line recurved ; legs of ante- 

 rior pair reddish, those of posterior two pairs 

 reddish, with deep black stripe on distal end 

 of patella, tibia, protarsus, and tarsus ; cara- 

 pace much lon^r than tibia 1 and longer 

 than tarsus and piotarsus 4 rujipalpis, Luc.
