brown ; cup-shape, shallow ; pars digitalis well developed, 

 ovate ; laminae bulbi yellow-ochreous, base clouded ; ovate ; 

 rugose ; moderately haired, directed towards each other ; 

 genital bulb moderately complicated, the pointed apophyses 

 will most attract attention. A long, wide, tapering, fuscous 

 apophysis springs from near fore-half, follows superior- 

 posterior margin of bulbus, free end curves forwards and 

 upwards, margins involute; second apophysis fuscous, broad, 

 tapers rapidly, projects forwards from extremity of bulb ; 

 immediately below the latter organ is a reddish process, basal 

 half depressedly conical, fore-part sharply compressed and 

 pointed. 



The abdomen resembles that of the female both in form 

 and markings ; coloration of type specimen of a somewhat 

 lighter and duller tone.

Fern. — Ceph.-th., long, 1-5 ; broad, 1-4. Abd., long, 2-5 ; 

 wide, 1-4. Legs, 4, 1, 2, 3 = 9-2, 9, 6, 4-4 mm. 



Cephalothorax ochraceous-yellow, cephalic region suffused 

 with lake ; border-hem and strias mottled with olive-green ; 

 sparsely furnished with yellowish hairs. Cephalic parts and 

 eyes do not differ essentially from the male's. 



Legs pale-brown, patellary rings dark ; yellowish-brown 

 central and distal annuli on femoral, tibial, and metatarsal 

 joints ; hairs sparse ; bristle-like spines on patellae and tibiae. 



Palpi pale-brown ; moderately long and slender. 



Abdomen from the acutely-emarginate base is gradually 

 enlarged to posterior third, from thence pointed to anus ; a 

 low tubercular elevation occurs at each lateral angle ; tw T o 

 fore-thirds of profile somewhat level, posterior third inclined 

 moderately to spinners ; ground-colour yellowish olive-green, 

 clouded with a deeper tone ; folium lanceolate, occupies dorsal 

 area from base to tubercles, clouded with fuscous-lake, few 

 whitish spots ; border cream-colour, spotted with lake dots ; 

 lateral margins and hind- slope clouded with fuscous-green ; 

 rather sparingly clothed with yellowish hairs. Vulva repre- 

 sents a large, shallow, somewhat reniform area, of an orange- 

 colour, red-lake reflections, rising to a slight central ridge, 

 whose up-turned, superior extremity exhibits two moderate- 

 sized, oval foveae, divided by a septum perceptibly narrower 

 than their transverse or greater breadth ; superior and lateral 

 borders of area bounded by w T ell-developed, incurved costae.
