ANT-LIKE SPIDERS FROM MALAYA. 299 



J . The chief differences from § are : — 



Prosoma. — Caput very much higher and back wall nearly- 

 vertical, so that caput is about three times as high as groove and 

 twice as high as thorax, standing up like a square tower (text- 

 fig. 6, a). 



Eyes. — 4-rim = 4 . 4 or very nearly. 



Falces. — Longer than prosoma, after an initial sharp con- 

 striction at top they curve outwards to ^ and then in ; end cut 

 square but somewhat pointed forward at inner corner in con- 

 tinuation of straight inner edge. On side view upper edge is 

 convex, widest at centre, lower straight. Width = ^ length. 

 Nearly horizontal. Unguis, length slightly < paturon, S curve 

 with branches much flattened but sharp curve at tip, considerably 

 thicker and darker at base than tip. Groove not defined. Upper 

 margin contains 7 teeth, of which the first 2 are close to base of 

 margin, the 4 at least are strong and subevenly spaced, the last a 

 little weaker. Lower mai-gin 6 or 7 teeth, very small, and much 

 further apart at apical than basal end, but teeth a little variable. 



Palpi. — Tibia only a little lai'ger than patella, with moderately 

 strong pointed black-tipped jDrocess on upper outer apex. Tarsus 

 has fovea large and extending nearly to the end, with a fine spine 

 encircling rather more than once. 



Legs. — The contrasts of colouring are not nearly so distinct 

 as in $ . 



Opisthosoma. — White belt missing. Upper and centre of 

 iower sides coriaceous. 



Short Description. 



Prosoma = opisthosoma. Caput = thorax. Caput very high 

 with nearly vertical walls, tower-like in (S , not so marked in $ . 

 Occasionally faint white-haired cephalic wedge. 



2 falx. Upper teeth 5 to angle with 1 or 2 dots beyond ; 

 lower teeth 6, as strong as upper, close. 



S falx. Longer than prosoma, width ^ length, outer edge 

 •convexly curved on upper and side aspect. Upper teeth 6 or 7, of 

 which first two comparatively close to root of unguis. Lower 6 

 dots wider spaced at root of unguis. Unguis slightly < paturon, 

 flat S curve with rather shai-p curve at point. 



$ palp. Tarsus = 2 tibia. 



S palp. Tibia has moderate, black-pointed, slightly curved 

 process at outer upper apex. Organs surrounded by circle and a 

 bit of thin black spine. 



Legs 4.1.3.2, with marked difference between each 2 ; anterior 

 .pairs lighter than posterior, but not always in S , dark side-lines 

 in some joints, p^ 1 spine pair ; ti^ 5 spine pairs, evenly spaced, 

 not very strong ; m^ 2 spine pairs ; ti„ 3 spine pairs neai-ly as 

 vstrong as on ti^ ; m., 2 spine pairs nearly as strong as on ti.,. 



Pedicel nearly as long as caput, 2nd joint very short as 

 •compared with 1st.
