I/ . Resembles the I/ of P. indica ; differs in the head, thorax 

 and abdomen being almost uniform chestnut-red, with the an- 

 tennas and legs yellowish red. Pilosity and pubescence as in 

 P. indica. The striaa on the head are wider apart and lighter, 

 and less curved transversely outwards on the posterior lateral 

 angles ; the head itself is rectangular, as broad posteriorly as in 

 front ; the eyes larger and more prominent ; the scape of the 

 antenna} shorter, barely reaching half the distance from its 

 insertion to the top of the head. Thorax proportionately slightly 

 broader than in P. indica, the pronotum somewhat laterally 

 tuberculate, the metanotal spines shorter. The rest as in 

 P. indica. 



$ . Differs from the $ of P. indica in being rather more 

 slenderly built, with proportionately shorter antennae and longer 

 legs ; the head is broader posteriorly ; the scape of the antennae 

 extending beyond the top of the head by less than one-fourth of 

 its length from insertion ; the metanotal spines are distinctly 

 shorter, and in colour the head and abdomen are darker. 



Length, I/ 3*5-4-5 ; g 2-2-5 mm.

303. Phidole allani, sp. nov. 



I/. Eather bright reddish or yellowish brown, antennaj and 

 legs reddish yellow ; head somewhat coarsely longitudinally striate 

 up to a little beyond the vertex ; the occiput and lateral lobes 

 above smooth ; the pronotum of the thorax in front and the meta- 

 notum transversely striate, the sides of the thorax somewhat 

 irregularly closely rugulose, granulate : legs, pedicel and abdomen 

 smooth; the whole insect bright and shining; pilositv pale yellow, 

 long and abundant, especially on the abdomen. Head remarkably 

 thick, short and broad, as broad as long, the occipital ernar- 

 gination moderate and wide, the medial frontal sulcation broad 

 and distinct ; mandibles smooth and shining, not punctate ; 

 clypeus in the middle smooth and polished, its anterior margin 

 transverse ; antennal carinaB short, wide apart, divergent, con- 

 tinued back as stria? about the length of the scape ; the antennal 

 hollow for the latter not well-marked ; antennae of moderate 

 length, the scape falling short of the top of the head by one-third 

 of its own length ; eyes lateral, placed low down in the lower 

 third of the side of the head. Thorax : the pronotum somewhat 

 flat in front, the lateral tubercles fairly well-marked, the trans- 

 verse mesonotal furrow shallow, the ridge or carina behind it 

 thick ; the basal portion of the metanotum short, rather flat, 

 slightly raised ; metanotal spines short, erect and stout. Pedicel 

 stout, the 1st node in profile subtriangular, anteriorly curved 

 inwards, transverse and emarginate above, without any appendix
