thorax, legs and petiole being dark reddish brown, the pronotum more 

 reddish than the rest of the thorax, the anterior three-fifths of the head 

 ferruginous or sometimes ochreous red. It differs from the £ minor of 

 vestitus in having the head much shorter or only a quarter longer 

 than wide, widest just behind the eyes, which are much larger and more 

 convex than in vestitus, placed at the posterior third. The head is 

 also less narrowed in front, the anterior margin being at least three- 

 fourths as wide as the greatest width (two-thirds or less in vestitus). 

 Epinotum like that of the 2j.. Otherwise like the 2|. 



"$. Two $, ex. coll. Saussure, from Mozambique, probably 

 belong to this species, but they have lost the abdomen. Probable 

 length 11 mm. Colour, pubescence, sculpture and pilosity as in the 

 $. Head elongate, almost rectangular, slightly widened behind. 

 Clypeus as in the £. Epinotum rounded. Scale rounded, thinner 

 than in the $, slightly emarginate above in one of the specimens. 

 Wings very slightly yellowish, the nervures distinct."

The nest is placed in bare patches of ground like that of P. custodiens, 

 and, as is the case with that species, the excavated material is sprinkled 

 in a thin layer over a large radius. This ant has the same jerky 

 movements as custodiens, and, in addition to the similarity in the 

 arrangement of the abdominal pubescence, the $ minor, like that of 

 custodiens, is much more darkly coloured than its 2J.. Altogether it is 

 deceptively like custodiens in life, and without doubt is a mimic of that 

 powerful species.
