Whole body covered with long, suberect, golden yellow hairs, which on 

 the head, thorax and abdomen, arise from the umbilicate centers of the 

 foveolte. Hairs on the terminal antennal joint very short and dense, con- 

 trasting with the longer hairs on the scape and short joints of the funicle. 

 Color red, edges of mandibles, clypeus, anterior border and posterior 

 angles of head, the funicle with the exception of the terminal joint, the 

 articulations of the thorax, legs and abdomen and the tip of the latter black- 



ish. Legs and terminal antennal joint slightly 

 more yellowish than the remainder of the 

 body. 



Female (Fig. 2). Length 3.75 mm. 

 Eyes moderately large, convex, situated 

 in the middle of the lateral surface of the 

 head, which is shaped like that of the 

 worker. Ocelli well developed, not lying 

 at the corners of an equilateral, but of an 

 isosceles triangle with a long base. Pro- 

 thorax large, scutum of mesonotum well 

 developed, dorsally flattened, without para- 

 psidal sutures ; tegulse large, elliptical ; no 

 paraptera between the scutum and the well- 

 developed, flattened scutellum, metanotum 

 narrow but distinct ; epinotum large, shaped 

 like that of the worker. On the pleural sur- 

 face the mesothoracic epimerite and epi- 

 sternum are distinct but these elements in 

 the metapleurae are more obscurely separ- 

 ated. There is nothing to show that the 

 thorax has ever borne wings. Petiole longer 

 than broad, postpetiole almost twice as broad 

 the petiole> its posterior border nearly

aupnt* n. sp. Apterous female. cogxtensive wkh the edge of the first gastric 



segment, which is both broader and longer than this segment in the worker. 

 Terminal gastric segments and sting in all respects like those of the worker. 

 The sutures of the thoracic dorsum are blackened ; otherwise the female 

 is like the worker in coloration, sculpture and pilosity. 



As Cerapachys aitgusta has II -jointed antennae it must be 

 placed in Emery's subgenus Parasysda. Emery ('oi a and 'oi 1 ') 

 has recently published a revision of the ants of the subgenus 

 Cerapachys and the allied genera which he groups together as 

 Cerapachyinae, a supertribal division comprising the following 

 tribes, genera and subgenera. 



Tribe i. Acanthostichii with the single South American genus 

 Acanthostichus Mayr.
