I am not quite certain if the specimens collected by Mr. Whymper are 

 identical with Ponera carbonaria, Sm., from Quito. Smith describes his species 

 as "jet-black," while the present species is bluish black, the bluish tinge 

 being very conspicuous, and is present even in the legs, although not so 

 strongly as on the body. The mandibles are deep black, very finely striated ; 

 along the inner edge is a row of large punctures, and it bears also some long, 

 reddish hairs, the outer edge having somewhat shorter pale hairs. In car- 

 bonaria, Smith, the mandibles are said to be " obscurely ferruginous." The 

 antennae are black, the apical joints obscurely punctured. The eyes are 

 situated opposite the base of the frontal laminse, which aie finely punctured. 

 The frontal suture is deep ; it originates about the centre of the frontal 

 laminse, and anteriorly curves round the triangular frontal area, which is not 

 defined from the clypeus. The frontal laminte are curved, narrower at base 

 than at apex, and from behind the antennas project into a tubercle-like 

 dilatation. The antennal and clypeal foveas are united. Clypeus incised 

 at the apex. The front of the head is finely longitudinally striated. Smith 

 describes the pubescence on his carbonaria as " yellowish " ; in the present 

 species it is whitish, ferruginous on the metathoi\ax behind, and on the tibin- 

 and tarsi.
