306 MR. H. D. BADCOCK ON 



On the whole the legs strike one as dark, none of the coxee or 

 trochanters being really light. 



Sternum. — Blunt-pointed between ci.i, which are about \ width 

 apart, blunt- pointed between C1.2, which are not in contact, 

 swells out with straight edges between C2.3, which are wide, and 

 tapers to moderately long point in front of 4.4, which are in 

 contact. Widest =c.,. Dark mahogany as coxse. 



Pedicel nearly equals caput, j^ brown, longer than j^, below 

 = 2]^. 3^ light with black fore end. 



Opisthosoma — prosoma. Thin and round with broad con- 

 striction at ^. Brown above and below in front of epigastric fold, 

 which is slightly recurved. General colour very dark. 



Sphmers. — 1st light, stoutish, barrel-shaped. 2nd lighter^ 

 slenderer, cylindrical. 3rd longest, darker, slender, cylindrical. 



Anal tubercle. — Prominent, 2-jointed, 



Short Description. 



Prosoma = or slightly < opisthosoma. Cephalic groove rather 

 narrow, with thorax alDout half height of caput and wedge of 

 white hairs not very strong. 



S falx longer than caput < prosoma, flattened above. Unguis 

 as long as paturon, flat S curved, with very short knob-like 

 branch. Upper teeth 9, lower 10, but lines liable to be confused. 



S palp = or nearly = falx. Tibia has short blunt process at 

 outer lower apex. Organs have a spine twisted spirally twice 

 and terminating pointing straight forward at inner apex. 



Legs 4.1.3.2 with difference 3 . 2 slight, no very marked 

 colour contrasts. Tr^ 4 spine pairs, m^ 2 pairs, ti^ 3 pairs, m^ 

 2 pairs. 



Pedicel nearly = caput, with 1st joint markedly greater than 

 2nd, especially below. 



Opisthosoma widely constricted at |, with longitudinal brown 

 coriaceous mai'ks above and below and in front of epigastric fold. 



Note. — Description is based on 4 c? from Bukit Besar and 

 Biserat, two of the specimens from the latter associated with 

 ants nos. 9 and 16 respectively. There is not much diflference 

 between specimens except some variation in intensity of leg 

 colouring.
