This species is nocturnal, spinning large orb-webs at sun- 

 down among grasses and other foliage, usually beside a stream or 

 tank, and resting by day with its legs stretched out before and 

 behind on a blade of grass or a twig. It is readily distinguishable 

 from others by the forwardly directed first ventral tooth of the 

 female and by the large triangular first dorsal tooth of the male. 

 The armature of the fang is never very strong and may be 

 rudimentary or absent ; apart from this it bears a close general 

 resemblance to that of T. geniculata. 



Two very distinct forms occur, the typical one and a 

 variety which is described below under the name bidentata. For 

 t he most part these varieties seem to occur in different localities ; 

 but both are recorded from the Darjihng District and Southeni 

 Shan States. 



T. mandibulata, s. str. — The first three ventral teeth of the 

 female are very large and are followed without anj' long interval 

 by a number of smaller ones. The subapical spine of the male is 

 acuminate and simply pointed. 



Var. bidentata, nov.---The first ventral tooth of the female 

 is much the largest ; it is closely followed by the second, after 

 which there is a long interval without any teeth. The subapical 

 spine of the male is obliquely truncate.
