and the top of the head ; flagellum with the club formed of 4 

 subequal joints. Thorax anteriorly rounded, without lateral 

 tubercles ; transverse mesonotal groove and ridge well-marked ; 

 meso-metanotal suture wide and deep ; metanotum with its basal 

 portion laterally margined and strong erect lateral spines ; the 

 thorax somewhat irregularly but transversely striate, obliquely on 

 the sides. Pedicel rather thick : the 1st node, seen from the side, 

 cuneiform, without an appendix beneath ; 2nd node globose, 

 laterally slightly tuberculate, smooth above and shining; abdomen 

 smooth and shining. 



. Similar in colour, but lighter than in the If. , smooth, highly 

 polished and shining ; pilosity similar but more sparse. Head 

 broadly oval, with a distinct posterior margin ; antennae very long 

 and massive, the scape extending beyond the top of the head by 

 more than one-third of its length ; club of the flagellum of 4 sub- 

 equal joints as in the "ty. Thorax, nodes of the pedicel and 

 abdomen as in the I/, but proportionately smaller.

This species resembles Phidole (Ceratophidole) smyth-iesi, Forel, 

 in the form of the antennae. It differs in size and colour, in 

 having the head ( 11 ) proportionately smaller and longer, and 

 also in the shape of the head and thorax.

}/. Very light chestnut-red, smooth, polished and shining, 

 antenna?, legs and abdomen a shade paler; the head anteriorly 

 finely longitudinally striate, the thorax on the sides very sparsely 

 punctate ; pilosity entirely wanting, pubescence very short and 

 sparse. Head posteriorly broader than in front, deeply, widely 

 emarginate, without the mandibles a little longer than broad ; 

 mandibles sparsely punctate, the masticatory margin with two 

 indistinct blunt teeth at apex ; clypeus with the anterior margin 

 medially incised, a convex smooth spot in the middle with a tine 

 groove on each side ; antennal carinae very short, widely divergent 

 posteriorly, with no antennal groove ; antennae short, the scape 

 not reaching the top of the head by more than one-half of its 

 length from insertion ; eyes lateral, round, not very convex, placed 

 in anterior half of the head ; a distinct depression on the vertex ; 

 the posterior lateral angles of the head rounded but prominent. 

 Thorax : the pronotum a little longer than broad, convex above, 

 laterally tuberculate ; mesonotum transverse; the pro-mesonotal 

 suture deep and narrow, the meso-metauotal suture deep and broad ; 

 the metanotum with a curved slope to apex, the metanotal spines 

 very short and erect, Anterior node of the pedicel with a trans- 

 lucent appendix beneath, seen from above square, obliquely sloped
