pale, dark- centred fovea, most pronounced on lateral margins ; 

 ventral aspect fulvous, speckled, approximating to olive- 

 brown about sides, which display several vertical pale olive- 

 green lines. Corpus vulvce represent a large triangular, 

 longitudinally depressed scape, lying close to abdomen, 

 apex directed towards sturnum ; exhibits seven dis- 

 tinct yellowish stone-coloured wrinkles — the extremity, 

 which was somewhat damaged, apparently terminates 

 with three black, and several less pronounced reddish wrinkles ; 

 base of scapus roundly emarginate, project a brownish, gradu- 

 ally dilated septum, which curves round the incised margin, 

 of corpus ; latter represent two olive-brown lobes — bordering 

 the rima genitalis, surpassing in length, but otherwise not 

 differing essentially from wrinkles of scapus. 

 Single specimen.
