228 FOBAIICIDJE. 



placed in the lower third of the sides of the head. Thorax narrow 

 in comparison with the head, pronotum convex anteriorly, meso- 

 notum widely and deeply transversely sulcate and with a transverse 

 carina ; metanotum short, longitudinally sulcate, the metanotal 

 spines stout and acute. Anterior node of the pedicel without 

 appendix beneath, acutely transverse above ; posterior node 

 rounded above, much broader than long, slightly angularly pro- 

 duced at the sides ; abdomen broadly oval. 



. Similar in colour to the If.. Head oval, convex, very little 

 longer than broad ; scape of the antennae passing the top of the 

 head by about one-third of its length from insertion ; thorax 

 elongate, the metanotum proportionately longer than in the If. ; 

 pedicel as in the If., but the posterior node oval, longer than 

 broad ; abdomen broadly oval. Head, thorax and abdomen 

 smooth, polished and shining, the metanotum only delicately, 

 longitudinally striate on the sides ; pilosity as in the 1}.. 



$ . Closely resembles the 11 , darker in colour ; the head pro- 

 portionately somewhat smaller, but larger than the thorax ; 

 wetanotal spines broad at base. 



" <5 . Dull yellow. Wings long, pale brown, with the nervures 

 and stigma rather pale. Mandibles quadridentate. Scape of the 

 antennae as long as the first three joints of the flagellum. Head 

 arched transversely from one eye to the other. Thorax broad. 

 Sometimes the 2nd node very large, with a lateral tooth." (Forel.) 



Length, 11 6-8-5 ; 3-5-4-5 : $ 13 ; rf 5-5-6 mtn. 



Hab. Assam (Smythies). 



Remarkable for its having more than one form of as in 

 Phidologiton. It is one of the two Indian species with the apical 

 four instead of three joints of the flagellum of the antennae 

 subequal. 



Yar. bengalensis, Forel, has been described from Bengal. 

 Differs by its more elongate head and longer metanotal spines. 



256. Phidole bhavanae, sp. nov. 



If. . Dark castaneous brown, shining ; antennas and legs lighter, 

 somewhat reddish brown ; pilosity reddish yellow, abundant and 

 long on the front of the head and on the abdomen, somewhat 

 sparse on the thorax, on the antennae and legs it is oblique. Head 

 a little longer than broad, and broader posteriorly than in front, 

 longitudinally striate, reticulate in the intervals and on the posterior 

 lateral lobes, these latter somewhat pointed and cone-shaped, the 

 occipital emargination wide and deep, with a medial broad longi- 

 tudinally impressed line, but no transverse depression ; mandibles 

 shining, with sparsely scattered punctures ; clypeus with its anterior 

 margin transverse, not emarginate, a smooth space with a slight 

 vertical carina in the middle ; no antennal groove ; antennal 

 carinae short, scarcely divergent ; scape of antennae stout, 

 reaching about two-thirds of the distance between their insertion
