fulvous, approximating to stone-colour; hairs olive -green, 

 short, very scant ; patchy on dorsal aspect ; arranged on 

 lateral margins in somewhat horizontal lines. Corpus vulva 

 represents a pale straw-coloured, cordate elevation, occupied 

 by a large, yellow-ochreous, triangular-cordate, rugose, de- 

 pressed area, bounded by a longitudinally-wrinkled, involute 

 costa, studded with small papillae ; latter more thickly grouped 

 on a dark-brown arch which crowns the apex of the above- 

 mentioned area ; immediately below the arch, contiguous to 

 costa, are two pale, plano-convex, semi-oval lobes ; posterior 

 third of area exhibits a wide depressed septum, whose pro- 

 longed lake-browai margins are revolute at anterior end, in- 

 volute above the rima genitalis ; former project beyond latter.

Mas. — Ceph.-th., long, 1-8; broad, 1-1. Abd., long, 1-5; 

 broad, 1-6. Legs, 1, 2, 4, 3 = 15, 8-5, 6-7, 5 mm. 



Ccphalotliorax creamy - ochreous, speckled and stained 

 with a light yellow-brown ; cephalic band yellowish, mar- 

 gins brown ; broad ; basal fourth oval, bhiish centre spot ; 

 bifurcates to hind-row of eyes ; outer margin concave sinuate ; 

 few strong black hairs ; oval, lateral constriction at caput 

 moderate ; pars cephalica convex, eye-eminence broad, promi- 

 nent ; clypeus inclined forwards, projects over falces, height 

 equal to more than one-third depth of facial space ; thoracic 

 fovea blue-black, oval, longitudinal, fairly deep ;. radial striae 

 tolerably well marked ; caput grooves faint ; contour of profile 

 represents a prominent arch, posterior incline somewhat 

 steeper than anterior. 



Hind-row of eyes slightly procurved, median pair placed 

 on lake oval spots, separated by an interval equal to three- 

 fourths of an eye's diameter, about twice that space from 

 laterals ; anterior row strongly recurved, centrals smallest of 

 eight by one-third, encircled by dark rings, posited somewhat 

 obliquely, form with posterior pair a trapezoid much wider in 

 front than behind, more than their breadth from side-eyes ; 

 laterals have the pearl-grey lustre of hind-centrals, do not 

 differ essentially from them in size, seated obliquely on w^ell- 

 developed lake-coloured tubercular prominences, contiguous. 



Falces fulvous, second half suffused with olive-green ; nearly 

 one-fourth shorter than the pars humeralis of palpus, slender, 

 of somewhat even breadth, vertical. 



MaxlllcB ochraceous, green tinge ; long, slender, sensibly 

 enlarged forwards, round-pointed.
