PHIDOLE. 259 



erect red hairs. Head longitudinally striate, the striae running 

 into reticulations on the vertex and posterior lateral lobes ; no 

 transverse depression on the vertex, but a medial deeply impressed 

 line from the bottom of the occipital emargination ; mandibles 

 smooth, shining, sparsely punctured ; clypeus with the anterior 

 margiu medially bidentate ; autennal carinae divergent, antennal 

 grooves distinct, broadening at the top and delicately sculptured 

 within ; scape about half the length of the distance between its 

 insertion and the top of the head. Thorax transversely striate ; 

 the pronotum convex anteriorly, the lateral tubercles distinct, 

 obtuse ; transverse mesonotal groove and ridge not so distinctly 

 marked as in some other species (e. g. P. spathifera, striati- 

 ventris, &c.) ; metanotum short, the lateral spines long and acute. 

 Pedicel : the 1st node cuneiform, its upper margin transverse, 

 entire, without an appendix beneath ; the 2nd node transversely 

 striate, about twice as broad as long, laterally obtusely cone- 

 shaped ; abdomen broadly oval, shining, covered with piligerous 

 tubercles.

I/ . Bright light red ; the antennae, legs and abdomen brownish 

 or reddish yellow ; pilosity rather sparse and scattered, of a 

 bright yellowish red ; head longitudinally, rather finely, and not 

 deeply striate, the striae breaking into reticulations posteriorly ; 

 thorax finely transversely striate, finely punctured on the sides ; 

 pedicel slightly sculptured ; abdomen smooth and shining. Head 

 longer than broad, very slightly constricted towards the occiput, 

 the sides convex ; mandibles smooth, polished and very shining ; 

 clypeus advanced slightly in the middle and emarginate ; antennae 

 short, the scape falling short of the top of the head by two-thirds 

 of its length. Thorax anteriorly gibbous ; the prouotura without 

 lateral tubercles ; mesonotum slightly constricted, the transverse 

 groove and ridge well-marked; metanotum narrow, the meta- 

 notal spines very long and acute. Pedicel somewhat elongate, 

 the 1st node squamiform, the 2nd node from above transversely 

 oval, slightly fusiform ; abdomen oval. 



" . Head ovato-rectangular, with only a slightly distinct 

 posterior margin. The scape extends beyond the occiput by 

 two-thirds of its length. The pronotum forms a strong regular 

 convexity. Mesonotal furrow deep, behind which the meaonot urn 

 is raised and convex, without forming a transverse ridge. 

 Metanotum with two small teeth. Second node rounded. Smooth 

 and shining; sides of the thorax reticulate and subopaque. 

 Pilosity of the tibiaa short and a little oblique. Of a yellowish 

 red. Abdomen yellowish."
